dbus: update to 1.12.14.

dbus 1.12.14 (2019-05-17)
=========================

The “reclaimed floorboards” release.

Enhancements:

• Raise soft fd limit to match hard limit, even if unprivileged.
  This makes session buses with many clients, or with clients that make
  heavy use of fd-passing, less likely to suffer from fd exhaustion.
  (dbus!103, Simon McVittie)

Fixes:

• If a privileged dbus-daemon has a hard fd limit greater than 64K, don't
  reduce it to 64K, ensuring that we can put back the original fd limits
  when carrying out traditional (non-systemd) activation. This fixes a
  regression with systemd >= 240 in which system services inherited
  dbus-daemon's hard and soft limit of 64K fds, instead of the intended
  soft limit of 1K and hard limit of 512K or 1M.
  (dbus!103, Debian#928877; Simon McVittie)

• Fix build failures caused by an AX_CODE_COVERAGE API change in newer
  autoconf-archive versions (dbus#249, dbus!88; Simon McVittie)

• Fix build failures with newer autoconf-archive versions that include
  AX_-prefixed shell variable names (dbus#249, dbus!86; Simon McVittie)

• Parse section/group names in .service files according to the syntax
  from the Desktop Entry Specification, rejecting control characters
  and non-ASCII in section/group names (dbus#208, David King)

• Fix various -Wlogical-op issues that cause build failure with newer
  gcc versions (dbus#225, dbus!109; David King)

• Don't assume we can set permissions on a directory, for the benefit of
  MSYS and Cygwin builds (dbus#216, dbus!110; Simon McVittie)

• Don't overwrite PKG_CONFIG_PATH and related environment variables when
  the pkg-config-based version of DBus1Config is used in a CMake project
  (dbus#267, dbus!96; Clemens Lang)
