We need to ensure we call gst_pad_check_link() with the two pads in the correct
order. The order depends on wheter we iterate src or sink pads.

Check the sinkpad for the flushing state before calling the chainfunction on the
pad. We do this by checking the cache (which is also cleared on the srcpad when
the sink is set to flushing).
Fixes#641928
If after computing the suggestion with downstream caps we still have
a non-fixed suggestion caps try to intersect with the input caps
of the pad alloc to avoid useless renegotiations.

Improve the calculation of the duration. When we have no input duration set on
the input buffers stop is set to start and then we end up using a 0 duration in
the average calculation.
Keep track of the earliest allowed timestamp according to the latest
QoS report and drop buffers before that time. Activate this filter
when throttling is enabled. We could later also activate this in the
other QoS cases.
See #638891
Add a first draft with some ideas and use cases for the implementation
for bufferpools. The purpose is to be able to make elements negotiate
their buffer requirements as well as provide an infrastructure to
preallocate and reuse buffers in an easy way.
Failing to do so in the Windows case (implicitly triggered otherwise)
would have a subsequent _wait return immediately leading to high CPU
usage timeout loops.
Fixes#640675.
Make adding/removing gst_debug_log_default() work reliably in all
circumstances. The problem was that depending on platform and linker
flags the function argument might resolve to different addresses,
which made it impossible to remove the default log function added
in gst_init() from application code (because the pointer values
didn't match). The new approach should keep things simple by passing
NULL for the default function, which the code in libgstreamer can
then handle.

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().

Once we switch to normal mode, we're not typefinding anymore and thus the caps
will not change. Therefore can avoid the object lock in the data-flow path.
The locking was added in order to fix bug #608877.
Remove code that isn't needed any longer, which sets the multiqueue
to PLAYING and back before unreffing, in order to avoid a deadlock
waiting for gstpad tasks that were never started. The problem seems
to have been fixed long ago.
