Ensure that when multiple threads try to block a pad, only one of the threads
calls the callback. We do this by checking if the callback was already called.
The previous version unconditionally called the callback and then checked if it
was already called...
Also only call the unblock callback once from the first thread that unblocks.

This has undergone significant changes in implementation and
design in 0.11, and we're just not going to backport this to
0.10, so let's just remove it again and continue to fix this
up in master/1.0.
Context: Latency configuration should not be
messed up because of not-linked pads. In general,
one return FALSE on latency distribution causes
the "overall" pipeline latency configuration to
fail. This shows up as noise in logs (warning).
instead of just checking if the pad template caps would allow the caps.
The actually supported caps can be far more restrictive than the
template caps and only checking for the template caps can cause
incompatible caps to be set on a pad.
Fixes bug #677335.
The core will do this during dataflow already and additionally
does compatibility checks then. Let it be handled by the core
as for every other pad too.
Fixes bug #677335.
The linking behaviour of external variables that are not initialized
in the compilation unit where they are defined is undefined. On OS X
this causes a linking failure when statically linking GStreamer.
When the bin does an upward state change, try to avoid doing a downward state
change on the child and vice versa.
Add some more unit tests for this fix.

They can be used to select snapping behavior (to previous, next, or
nearest location, where relevant) when seeking.
The seeking implementation (eg, demuxer) may currently ignore some
or all of these flags.
After a writer has written to its reserved write location, it can only make the
location available for reading if all of the writers with lower locations have
finished.
Fix a race where the reader would see the updated the tail pointer before the
write could write the data into the queue. Fix this by having a separate reader
tail pointer that is only incremented after the writer wrote the data.
lseek() returns the offset if successful, and this is != 0 and
does not indicate an error. And if it does actually fail, don't
return FALSE (0) as an int, but -1. None of these things are
likely to have made a difference, ever. I don't think the offset
seek can ever actually happen, the current file position and the
current offset should always be increased in lock step, unless
there was an error in which case we'd just error out.
