Remove a pending async wakeup before we check if the next entry is UNSCHEDULED
because we might leave the control socket busy.

Keep a counter for the amount of outstanding wakeups that we produce and only
perform a write/read to the control socket when 1 or 0 respectively.
don't poll when waiting for the entries to be unblocked and clear their wakeup
counts, just act on the signal when the wakeup count is 0.
unscheduled entries will clear their wakeup count themselves.
Keep track of when we wakeup the async thread because the list of entries has
changed.
don't try to see if the list changed because we can't really know when one entry
is added multiple times.
Only wake up the async thread when we add an async entry to the head of the list
and the old entry was BUSY.

Note the changed behaviour of gst_poll_wait for timer GstPoll's, and
fix a couple of spelling errors.

when an entry being waited on in the async thread is unscheduled, clear the
wakeup queue so we can continue waiting on other entries.
When an entry being waited on in the async thread is unlocked because an earlier
entry was added to the list, set the entry to OK again. This makes sure that
only the entries being waited on have the BUSY flag set and wake up the timer
poll when they are unscheduled.

Saves some cycles/pandas for those of us who run uninstalled setups.

This helps prevent filesystem/data inconsistencies in certain
circumstances on certain filesystems (like ext4, xfs, ubifs).
Also see bug #562976.

Convenience API, mostly for image tags, so people don't have to
figure out the whole GValue/GstValue thing just for this.

Add some cleanups to the system clock tests, to free all the memory and
unschedule/unref all clock IDs we allocate.

Use a mutex in one test to avoid potential threading problems on multicore
machines.

This test randomly hangs if there are problems with the reliability of
unscheduling sync and async clockID's on the system clock.

Yes, 'codec' isn't exactly the best word, but let's be consistent with AUDIO_CODEC
and VIDEO_CODEC (which may be 'raw' formats as well after all). Prerequisite for
bug  #576552.

The command line option is --gst-debug-disable, not --gst-disable-debug.
Fixes #576556. Spotted by Bogdan Harjoc.

Use string deserialisation instead of custom parsing code to allow for all
supported ways of specifying property values.
fixes #576582.

Running configure with e.g. --disable-dst-debug was compiling out the debug
system (ABI break). Now stubs are added and only if one does e.g.
make CFLAGS="-DGST_REMOVE_DISABLED" the symbols are ommitted.

basesink: fix once-per-second 'emergency rendering' for case where all buffers but the very first are late

Due to a typo basesink didn't do any emergency rendering of late buffers
if the only buffer ever rendered was the first one with timestamp 0. This
means that in cases where the decoder is very very slow, we'd never see
any buffers but the very first one rendered. Fixes #576381.

Use 64-bit functions on windows to implement seeking in files bigger
than 4GB.
Fixes #575988

When generating arrays of control changes timestamp variable was used instead
the local ts variable that we increment when stepping through the array.
Pointed out by Martin Pokorny.

because we can, and for consistency.

A new argument allowed_exit_value was added in SVN recently (#574213).

We were converting the GstPadLinkReturn to a gboolean, which is not what we want
to do.

Add some of the bits needed for an uninstalled gst-rtsp-server (so gdb works
on the examples etc.). Python bits are still missing, and we might need an
-uninstalled.pc file as well in the future. Break up very long lines to make
them easier to read and maintain. Also remove gst-plugins paths from the
old days.

Add the new windows cmd.exe coloring method to the .def file.

Fixes #517231.

Refactor the debug line code to use as much code as possible for the win32 and
other color codings.
Update docs with new symbol.

Move the gst_pad_can_link() implementation from gstutils to gstpad and use
gst_pad_link_prepare() to make it work correctly and also check the caps.

Make the broken implementation in gstutils static.

Small cleanups in the _get_fixed_caps() function.

Fixes #575682.

Fixes build with -Werror caused by '_FILE_OFFSET_BITS redefined' warning on
OpenSolaris where _FILE_OFFSET_BITS may be defined both in our config.h
and via stdio.h (#575695).

Bin collects segment-start messages and segent-done messages. it posts a
segment-done message to its parent, once it has received a segment-done for
each segment-start. Imho it should also send a segment-start if it receives the
first segment start and if parent is !=NULL. This is needed for bins in bins,
so that also higher order bins can group segment-starts and segment-dones.
Right now higher order bins will post a segment-done for each segment-done
received.
