Drop in old GstBus code for the release to play it safe, since
regressions that are apparently hard to track down and reproduce
have been reported (on windows/OSX mostly) against the lockfree
version, and more time is needed to fix them.

... which happens in particular flushing a bus, possibly as part
of a state change, e.g. when having a pipeline in a pipeline
and then changing state back to NULL. The interior pipeline
will/might then flush the bus, which is a child bus from the
parent which does not have a poll anymore these days.
https://bugzilla.gnome.org/show_bug.cgi?id=648297
This allows to only create the socketpair when it is really required instead
of always creating it and immediately destroying it again for child buses.
https://bugzilla.gnome.org/show_bug.cgi?id=647005
This is used by GstBin to create a child bus without
a socketpair because child buses will always work
synchronous. Otherwise too many sockets could be
created and the limit of file descriptors for the
process could be reached.
Fixes bug #646624.
Use new GstPoll functionality to wakeup the mainloop.
Use an atomic queue on the writer side to post the messages.
The reader side it protected with the lock still because we don't want multiple
concurrent readers.
Makes gst_bus_add_watch(), gst_bus_add_watch_full(), gst_bus_add_signal_watch(),
and gst_bus_add_signal_watch_full() convenience functions automatically pick up
any non-default main contexts set for the current thread via
g_main_thread_push_thread_default().
This either must never happen (which makes sense in this case) and thus should
use assert() or we should use a traditional if (poll_data->message) return;
to avoid differnet behaviour of intenal api when compiling with
G_DISABLE_CHECKS.
Adds that warning to configure.ac
Includes a tiny change of the GST_BOILERPLATE_FULL() macro:
The get_type() function is no longer declared before being defined.
https://bugzilla.gnome.org/show_bug.cgi?id=611692
This avoids:
* triple-checking for the GType when type-checking is enabled (see #597260)
* Avoids going through an expensive no-argument checking which landed in
glib-2.22
* Avoids going through 2 extrac functions (g_object_new -> g_object_new_valist)
There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.
Original commit message from CVS:
* gst/gstbus.c: (gst_bus_set_main_context), (gst_bus_create_watch):
Fix order of members in GstBusSource structure - the first member
must be the parent structure ie. GSource. Should make bus sources
attached to non-default main contexts work in all cases now (ie.
primarily in cases where the callback has a non-NULL user data
argument). Fixes#562170.
* tests/check/gst/gstbus.c: (test_custom_main_context):
Add unit test for the above, based on code by
Justin Karneges <justin at affinix com>.
Original commit message from CVS:
* gst/gstbus.c: (gst_bus_wakeup_main_context):
The lock order should be maincontext > OBJECT_LOCK so we need to release
the object lock when waking up the mainloop to avoid deadlocks.

Fix deadlock, g_source_get_id() cannot be called in finalize.
Keep track of the watch source by keeping a pointer to the source object
instead.
Use the bus lock to protect access to the pointer to the current
watch source.

Base on Patch by: Olivier Crete <tester at tester dot ca>
* gst/gstbus.c: (gst_bus_source_finalize),
(gst_bus_add_watch_full), (gst_bus_add_signal_watch_full):
Only allow one bus watch to be set at a time. This is necessary
because the dispatcher pops the message from the bus and the second
watcher will then get NULL or the next message (and the first won't
get this next message then, etc). If more than one "watcher" is
required signal watches should be used. Fixes bug #526044.

Patch by: Sjoerd Simons <sjoerd at luon net>
* gst/gstbus.c: (gst_bus_source_dispatch):
Don't print a warning if the queue is empty when we try to pop
here. That could happen if another thread or callback set the
bus to flushing between the source's check/prepare and the
dispatch being called (#531538).

emitted by default); log message structures of messages posted on
the bus as well.

_have_pending() takes a MessageType mask now too.
