- schannel_verify: Fix concurrent openings of CA file
  
  - Open the CA file using FILE_SHARE_READ mode so that others can read
    from it as well.
  
  Prior to this change our schannel code opened the CA file without
  sharing which meant concurrent openings (eg an attempt from another
  thread or process) would fail during the time it was open without
  sharing, which in curl's case would cause error:
  "schannel: failed to open CA file".

  HTTP3: fix invalid use of sendto for connected UDP socket
  
  On macOS/BSD, trying to call sendto on a connected UDP socket fails
  with a EISCONN error. Because the singleipconnect has already called
  connect on the socket when we're trying to use it for QUIC transfers
  we need to use plain send instead.

  HTTP3: fix Windows build
  
  The ngtcp2 QUIC backend was using the MSG_DONTWAIT flag for send/recv
  in order to perform nonblocking operations. On Windows this flag does
  not exist. Instead, the socket must be set to nonblocking mode via
  ioctlsocket.
  
  This change sets the nonblocking flag on UDP sockets used for QUIC on
  all platforms so the use of MSG_DONTWAIT is not needed.

  appveyor: Use two parallel compilation on appveyor with CMake
  
  Appveyor provides 2 CPUs for each builder[1], make sure to use parallel
  compilation, when running with CMake. CMake learned this new option in
  version 3.12[2] and the version provided by appveyor is fresh enough.
  
  Curl doesn't really take that long to build and it is using the slowest
  builder available, msbuild, so expect only a moderate improvement in
  build times.

- tests: use %FILE_PWD for file:// URLs
  
  This way, we always have exactly one slash after the host name, making
  the tests pass when curl is compiled with the MSYS GCC.
  
  Closes https://github.com/curl/curl/pull/4512

- tests: add `connect to non-listen` keywords
  
  These tests try to connect to ports nothing is listening on.
  
  Closes https://github.com/curl/curl/pull/4511

- runtests: get textaware info from curl instead of perl
  
  The MSYS system on Windows can run the test suite for curl built with
  any toolset. When built with the MSYS GCC, curl uses Unix line endings,
  while it uses Windows line endings when built with the MinGW GCC, and
  `^O` reports 'msys' in both cases. Use the curl executable itself to
  determine the line endings instead, which reports 'x86_64-pc-msys' when
  built with the MSYS GCC.

- examples/sslbackend: fix -Wchar-subscripts warning
  
  With the `isdigit` implementation that comes with MSYS2, the argument
  is used as an array subscript, resulting in a -Wchar-subscripts
  warning. `isdigit`'s behavior is undefined if the argument is negative
  and not EOF [0]. As done in lib/curl_ctype.h, cast the `char` variable
  to `unsigned char` to avoid that.

          curl_global_init(CURL_GLOBAL_DEFAULT);
          CURL*  handle=curl_easy_init();
          CookieInfo* info=Curl_cookie_init(handle,NULL,NULL,false);

          Curl_cookie_cleanup(info);

Jay Satiro (21 Sep 2019)
- socks: Fix destination host shown on SOCKS5 error
  
  Prior to this change when a server returned a socks5 connect error then
  curl would parse the destination address:port from that data and show it
  to the user as the destination:
  
  curld -v --socks5 10.0.3.1:1080 http://google.com:99
  * SOCKS5 communication to google.com:99
  * SOCKS5 connect to IPv4 172.217.12.206 (locally resolved)
  * Can't complete SOCKS5 connection to 253.127.0.0:26673. (1)
  curl: (7) Can't complete SOCKS5 connection to 253.127.0.0:26673. (1)
  
  That's incorrect because the address:port included in the connect error
  is actually a bind address:port (typically unused) and not the
  destination address:port. This fix changes curl to show the destination
  information that curl sent to the server instead:
  
  curld -v --socks5 10.0.3.1:1080 http://google.com:99
  * SOCKS5 communication to google.com:99
  * SOCKS5 connect to IPv4 172.217.7.14:99 (locally resolved)
  * Can't complete SOCKS5 connection to 172.217.7.14:99. (1)
  curl: (7) Can't complete SOCKS5 connection to 172.217.7.14:99. (1)
  
  curld -v --socks5-hostname 10.0.3.1:1080 http://google.com:99
  * SOCKS5 communication to google.com:99
  * SOCKS5 connect to google.com:99 (remotely resolved)
  * Can't complete SOCKS5 connection to google.com:99. (1)
  curl: (7) Can't complete SOCKS5 connection to google.com:99. (1)

  urlapi: avoid index underflow for short ipv6 hostnames
  
  If the input hostname is "[", hlen will underflow to max of size_t when
  it is subtracted with 2.
  
  hostname[hlen] will then cause a warning by ubsanitizer:
  
  runtime error: addition of unsigned offset to 0x<snip> overflowed to
  0x<snip>
  
  I think that in practice, the generated code will work, and the output
  of hostname[hlen] will be the first character "[".
  
  This can be demonstrated by the following program (tested in both clang
  and gcc, with -O3)
  
  int main() {
    char* hostname=strdup("[");
    size_t hlen = strlen(hostname);
  
    hlen-=2;
    hostname++;
    printf("character is %d\n",+hostname[hlen]);
    free(hostname-1);
  }
  
  I found this through fuzzing, and even if it seems harmless, the proper
  thing is to return early with an error.

- curl_multi_poll: a sister to curl_multi_wait() that waits more
  
  Repeatedly we see problems where using curl_multi_wait() is difficult or
  just awkward because if it has no file descriptor to wait for
  internally, it returns immediately and leaves it to the caller to wait
  for a small amount of time in order to avoid occasional busy-looping.
  
  This is often missed or misunderstood, leading to underperforming
  applications.
  
  This change introduces curl_multi_poll() as a replacement drop-in
  function that accepts the exact same set of arguments. This function
  works identically to curl_multi_wait() - EXCEPT - for the case when
  there's nothing to wait for internally, as then this function will by
  itself wait for a "suitable" short time before it returns. This
  effectiely avoids all risks of busy-looping and should also make it less
  likely that apps "over-wait".
  
  This also changes the curl tool to use this funtion internally when
  doing parallel transfers and changes curl_easy_perform() to use it
  internally.

- easy: resize receive buffer on easy handle reset
  
  - In curl_easy_reset attempt to resize the receive buffer to its default
    size. If realloc fails then continue using the previous size.
  
  Prior to this change curl_easy_reset did not properly handle resetting
  the receive buffer (data->state.buffer). It reset the variable holding
  its size (data->set.buffer_size) to the default size (READBUFFER_SIZE)
  but then did not actually resize the buffer. If a user resized the
  buffer by using CURLOPT_BUFFERSIZE to set the size smaller than the
  default, later called curl_easy_reset and attempted to reuse the handle
  then a heap overflow would very likely occur during that handle's next
  transfer.

  libcurl: Restrict redirect schemes
  
  All protocols except for CURLPROTO_FILE/CURLPROTO_SMB and their TLS
  counterpart were allowed for redirect. This vastly broadens the
  exploitation surface in case of a vulnerability such as SSRF [1], where
  libcurl-based clients are forced to make requests to arbitrary hosts.
  
  For instance, CURLPROTO_GOPHER can be used to smuggle any TCP-based
  protocol by URL-encoding a payload in the URI. Gopher will open a TCP
  connection and send the payload.
  
  Only HTTP/HTTPS and FTP are allowed. All other protocols have to be
  explicitly enabled for redirects through CURLOPT_REDIR_PROTOCOLS.

  http2: Stop drain from being permanently set on
  
  Various functions called within Curl_http2_done() can have the
  side-effect of setting the Easy connection into drain mode (by calling
  drain_this()).  However, the last time we unset this for a transfer (by
  calling drained_transfer()) is at the beginning of Curl_http2_done().
  If the Curl_easy is reused for another transfer, it is then stuck in
  drain mode permanently, which in practice makes it unable to write any
  data in the new transfer.
  
  This fix moves the last call to drained_transfer() to later in
  Curl_http2_done(), after the functions that could potentially call for a
  drain.

- version: make ssl_version buffer match for multi_ssl
  
  When running a multi TLS backend build the version string needs more
  buffer space. Make the internal ssl_buffer stack buffer match the one
  in Curl_multissl_version() to allow for the longer string. For single
  TLS backend builds there is no use in extended to buffer. This is a
  fallout from #3863 which fixes up the multi_ssl string generation to
  avoid a buffer overflow when the buffer is too small.

- Revert "multi: support verbose conncache closure handle"
  
  This reverts commit b0972bc.
  
  - No longer show verbose output for the conncache closure handle.
  
  The offending commit was added so that the conncache closure handle
  would inherit verbose mode from the user's easy handle. (Note there is
  no way for the user to set options for the closure handle which is why
  that was necessary.) Other debug settings such as the debug function
  were not also inherited since we determined that could lead to crashes
  if the user's per-handle private data was used on an unexpected handle.
  
  The reporter here says he has a debug function to capture the verbose
  output, and does not expect or want any output to stderr; however
  because the conncache closure handle does not inherit the debug function
  the verbose output for that handle does go to stderr.
  
  There are other plausible scenarios as well such as the user redirects
  stderr on their handle, which is also not inherited since it could lead
  to crashes when used on an unexpected handle.
  
  Short of allowing the user to set options for the conncache closure
  handle I don't think there's much we can safely do except no longer
  inherit the verbose setting.

  OpenSSL: Report -fips in version if OpenSSL is built with FIPS
  
  Older versions of OpenSSL report FIPS availabilty via an OPENSSL_FIPS
  define. It uses this define to determine whether to publish -fips at
  the end of the version displayed. Applications that utilize the version
  reported by OpenSSL will see a mismatch if they compare it to what curl
  reports, as curl is not modifying the version in the same way. This
  change simply adds a check to see if OPENSSL_FIPS is defined, and will
  alter the reported version to match what OpenSSL itself provides. This
  only appears to be applicable in versions of OpenSSL <1.1.1

  With transfers being queued up, we only move one at a a time back to the

  move of another pending transfer. Previously, it would otherwise wait

- tests: Run global cleanup at end of tests
  
  Make sure to run curl_global_cleanup() when shutting down the test
  suite to release any resources allocated in the SSL setup. This is
  clearly visible when running tests with PolarSSL where the thread
  lock calloc() memory which isn't released when not running cleanup.

  Commit 9081014 fixed most of the confusing issues between scope id and

- cmake: avoid linking executable for some tests with cmake 3.6+
  
  With CMAKE_TRY_COMPILE_TARGET_TYPE set to STATIC_LIBRARY, the try_compile()

  instead of executable. This avoids linking additional libraries in and thus
  speeds up those checks a little.

  AmiSSL is an Amiga native library which provides a wrapper over OpenSSL.

  For the Linux builds, GCC 8 and 7 and clang 7 were installed, but the
  new GCC versions were only used for the coverage build and for building
  nghttp2, while the new clang version was not used at all.
  
  BoringSSL needs to use the default GCC as it respects CC, but not CXX,

- doh: inherit some SSL options from user's easy handle
  
  - Inherit SSL options for the doh handle but not SSL client certs,
    SSL ALPN/NPN, SSL engine, SSL version, SSL issuer cert,
    SSL pinned public key, SSL ciphers, SSL id cache setting,
    SSL kerberos or SSL gss-api settings.
  
  - Fix inheritance of verbose setting.
  
  - Inherit NOSIGNAL.
  
  There is no way for the user to set options for the doh (DNS-over-HTTPS)
  handles and instead we inherit some options from the user's easy handle.
  
  My thinking for the SSL options not inherited is they are most likely
  not intended by the user for the DOH transfer. I did inherit insecure
  because I think that should still be in control of the user.
  
  Prior to this change doh did not work for me because CAINFO was not
  inherited. Also verbose was set always which AFAICT was a bug (#3660).

  The closure handle is a special easy handle used for closing cached

- 10-at-a-time.c: fix too long line

- [Arnaud Rebillout brought this change]

  examples: various fixes in ephiperfifo.c
  
  The main change here is the timer value that was wrong, it was given in
  usecs (ms * 1000), while the itimerspec struct wants nsecs (ms * 1000 *
  1000). This resulted in the callback being invoked WAY TOO OFTEN.
  
  As a quick check you can run this command before and after applying this
  commit:
  
      # shell 1
      ./ephiperfifo 2>&1 | tee ephiperfifo.log
      # shell 2

  If the cookieinfo pointer is NULL there really is nothing to save.
  
  Without this fix, we got a problem when a handle was using shared object
  with cookies and is told to "FLUSH" it to file (which worked) and then
  the share object was removed and when the easy handle was closed just
  afterwards it has no cookieinfo and no cookies so it decided to save an
