[libmicrohttpd] GNU libmicrohttpd 0.9.73 released

[Evgeny Grin]

Dear all,

I'm glad to announce the release of GNU libmicrohttpd 0.9.73.
This release brings new features, improvements, and a few fixes.
The most important addition is the new function for vector-backed
responses, based on the patch contributed by NASA engineers.
Other changes include compatibility with autoconf 2.70+, improved
testsuite compatibility with CI systems, fixed and improved MSVC
builds, and implemention of ALPN support.

More detailed list of notable changes since version 0.9.72:

API changes:
+ Added new function MHD_create_response_from_iovec(), based on the
  patch provided by Lawrence Sebald and Damon N. Earp from NASA.
+ Added MHD_OPTION_SIGPIPE_HANDLED_BY_APP daemon option.
+ Added new function MHD_run_wait().
+ Added MHD_OPTION_TLS_NO_ALPN to disable usage of ALPN even if
  it is supported by TLS library.

New features:
+ Added '--enable-heavy-tests' configure parameter (disabled by
  default).
+ Implemented support for ALPN.

Improvements and enhancements:
* Return timeout of zero also for connections awaiting cleanup.
* Compatibility with autoconf >=2.70, used new autoconf features.
* Warn user when custom logger option is not the first option.
* Added information to the header about minimal MHD version when
  particular symbols were introduced.
* Updated test certificates to be compatible with modern browsers.
* Added on-fly detection of UNIX domain sockets and pipes, MHD does
  not try to use TCP/IP-specific socket options on them.
* Report more detailed error description in the MHD log for send
  and receive errors.
* Enabled bind port autodetection for MSVC builds.

Fixes:
# Fixed PostProcessor to always properly stop iteration when
  application callback tells it to do so.
# Fixed MD5 digest authorization broken when compiled without
  variable length arrays support (notably with MSVC).
# Fixed detection of type of send errors on W32.

It's worth noting the FreeBSD 13 implementation of EventFD has
been tested and works out-of-box, without any modifications or
patches.
