* dbus/dbus-threads.c:
* dbus/dbus-threads.h:
Add condvars. Remove static mutext from API.
Implement static mutexes by initializing them from threads_init.
* glib/dbus-gthread.c:
* qt/dbus-qthread.cpp:
Update with the thread api changes.
* dbus/dbus-list.c:
* dbus/dbus-list.h:
Turn StaticMutex into normal mutex + init function.
Export new functions _dbus_list_alloc_link, _dbus_list_free_link,
_dbus_list_append_link, _dbus_list_prepend_link
* dbus/dbus-sysdeps.c:
* dbus/dbus-sysdeps.h:
New type dbus_atomic_t, and new functions _dbus_atomic_inc,
_dbus_atomic_dec. Only slow fallback implementation at the moment.
* dbus/dbus-protocol.h:
Add DBUS_MESSAGE_LOCAL_DISCONNECT define
* dbus/dbus-message.c:
Make ref/unref atomic.
Fix some docs.
* dbus/dbus-connection-internal.h:
* dbus/dbus-connection.c:
* dbus/dbus-connection.h:
Make threadsafe.
Change _peek to _borrow,_return & _steal_borrowed.
Change disconnect callback to event.
Make dbus_connection_dispatch_messages reentrant.
* dbus/dbus-transport.c:
Don't ref the connection on calls to the transport
implementation.
* dbus/dbus-message-handler.c:
Make threadsafe.
* glib/dbus-gmain.c:
Don't use peek_message anymore
* test/Makefile.am:
* test/debug-thread.c:
* test/debug-thread.h:
Simple thread implementation that asserts() on deadlocks in
single-threaded code.
* test/bus-test.c:
(main) Call debug_threads_init.
* test/watch.c:
Use disconnect message instead of disconnect callback.
* bus/connection.c:
* bus/connection.h:
Don't call dbus_connection_set_disconnect_function. Instead export
bus_connection_disconnect.
* bus/dispatch.c:
Call bus_connection_disconnect when we get a disconnected message.
