Update to 0.7.22:

telepathy-glib 0.7.22 (2009-01-13)
==================================

The "TP_STRUCT_TYPE_BROWN_PAPER_BAG" release.

Fixes:

* Accept message=NULL in tp_group_mixin_change_members, as documented and true
  in the past, rather than crashing.

telepathy-glib 0.7.21 (2009-01-12)
==================================

The "TP_HASH_TYPE_PINT_HOBGOBLIN_MOUTH_MAP" release.

Enhancements:

* Updated to spec version 0.17.17
  - Added TP_HASH_TYPE_HANDLE_IDENTIFIER_MAP and
    TP_HASH_TYPE_MESSAGE_PART_CONTENT_MAP

* (Finally) merged TpMessageMixin, which can be used in place of TpTextMixin to
  implement the Messages interface on Text channels.

* The examples have been made more exemplary, using TpChannelManager in place
  of TpChannelFactoryIface, implementing Destroyable and respawning 1-1 text
  channels which are closed with pending messages.

* Added a TP_COMPILER_WARNINGS macro to simplify choosing compiler warnings in
  configure.ac, and forked a version of AS_COMPILER_FLAG that supports C++ so
  that TP_COMPILER_WARNINGS can be used for C++ projects (such as
  telepathy-qt4).  Other projects using telepathy-glib's warnings might want to
  copy m4/tp-compiler-*.m4 and use TP_COMPILER_WARNINGS.

* Added support to TpGroupMixin for emitting the MembersChangedDetailed signal
  (fd.o #19050 and #19052), and to TpChannel for listening to it when possible
  (fd.o #19051).

* Added tp_channel_get_identifier

* Added support for parsing the dbus-property CM parameter flag (introduced in
  spec 0.17.16) from .manager files (fd.o #19053).

Fixes:

* Various Win32 portability fixes (from Sunil Mohan Adapa on fd.o #19461).

* fd.o #19101: tp_connection_get_contacts_by_id() crashes
