Announcing dbus 1.13.16

This is a development branch for the adventurous, and comes with a risk
of regressions. OS distributions should stay with the 1.12.x branch,
unless they can commit to following the 1.13.x branch until it reaches
a 1.14.0 stable release at an unspecified point in the future.

git tag: dbus-1.13.16

The “ominous mushroom hat” release.

Denial of service fixes:

• CVE-2020-12049: If a message contains more file descriptors than can
  be sent, close those that did get through before reporting error.
  Previously, a local attacker could cause the system dbus-daemon (or
  another system service with its own DBusServer) to run out of file
  descriptors, by repeatedly connecting to the server and sending fds that
  would get leaked.
  Thanks to Kevin Backhouse of GitHub Security Lab.
  (dbus#294, GHSL-2020-057; Simon McVittie)

Enhancements:

• The API reference manual can be built as a Qt compiled help file if
  qhelpgenerator(-qt5) is available. This is controlled by
  --enable-qt-help and --with-qchdir in the Autotools build, or
  -DENABLE_QT_HELP and -DINSTALL_QCH_DIR in CMake.
  (dbus!150, Ralf Habacker)

Fixes:

• When built for Windows, return all autolaunch error information in
  the DBusError rather than printing some of it to stderr
  (dbus#191, dbus!131; Ralf Habacker)

• When built for Windows, don't truncate long log messages
  (dbus!134, Ralf Habacker)

• When built using CMake for a Unix platform, dbus-cleanup-sockets and
  dbus-uuidgen are now included (dbus!154, Ralf Habacker)

• When built for Windows with verbose mode enabled, don't print debugging
  messages related to poll() emulation into a fixed-size buffer that
  could overflow (dbus!125, Ralf Habacker)

• Adjust .desktop file parser to avoid a Coverity false positive
  (dbus!146, Coverity CID 354884; Ralf Habacker)

• Print shell-test diagnostics to stderr, avoiding warnings or errors
  from strict TAP parsers (dbus!157, Félix Piédallu)

Tests and CI enhancements:

• When the CI cross-builds Windows binaries on Linux, run unit tests
  using Wine (dbus#296, dbus!158; Ralf Habacker)

• Really build x86_64 Windows binaries in Gitlab-CI, instead of building
  i686 binaries a second time (Ralf Habacker)

• When tests will be run using Wine, use STABS debug symbol format so
  that Wine can display backtraces (dbus#133, dbus!104; Ralf Habacker)
