Update to 1.8.8, many security fixes.

D-Bus 1.8.8 (2014-09-16)
==

The "smashy smashy egg man" release.

Security fixes:

* Do not accept an extra fd in the padding of a cmsg message, which
  could lead to a 4-byte heap buffer overrun.
  (CVE-2014-3635, fd.o #83622; Simon McVittie)

* Reduce default for maximum Unix file descriptors passed per message
  from 1024 to 16, preventing a uid with the default maximum number of
  connections from exhausting the system bus' file descriptors under
  Linux's default rlimit. Distributors or system administrators with a
  more restrictive fd limit may wish to reduce these limits further.

  Additionally, on Linux this prevents a second denial of service
  in which the dbus-daemon can be made to exceed the maximum number
  of fds per sendmsg() and disconnect the process that would have
  received them.
  (CVE-2014-3636, fd.o #82820; Alban Crequy)

* Disconnect connections that still have a fd pending unmarshalling after
  a new configurable limit, pending_fd_timeout (defaulting to 150 seconds),
  removing the possibility of creating an abusive connection that cannot be
  disconnected by setting up a circular reference to a connection's
  file descriptor.
  (CVE-2014-3637, fd.o #80559; Alban Crequy)

* Reduce default for maximum pending replies per connection from 8192 to 128,
  mitigating an algorithmic complexity denial-of-service attack
  (CVE-2014-3638, fd.o #81053; Alban Crequy)

* Reduce default for authentication timeout on the system bus from
  30 seconds to 5 seconds, avoiding denial of service by using up
  all unauthenticated connection slots; and when all unauthenticated
  connection slots are used up, make new connection attempts block
  instead of disconnecting them.
  (CVE-2014-3639, fd.o #80919; Alban Crequy)

Other fixes:

* Check for libsystemd from systemd >= 209, falling back to
  the older separate libraries if not found (Umut Tezduyar Lindskog,
  Simon McVittie)

* On Linux, use prctl() to disable core dumps from a test executable
  that deliberately raises SIGSEGV to test dbus-daemon's handling
  of that condition (fd.o #83772, Simon McVittie)

* Fix compilation with --enable-stats (fd.o #81043, Gentoo #507232;
  Alban Crequy)

* Improve documentation for running tests on Windows (fd.o #41252,
  Ralf Habacker)
