c47e49e1e3 pad: Unblock blocking pad probes when receiving FLUSH_START in send_event() too 
Without this, flushing might not unblock the streaming thread and cause deadlocks.

5af73b30ed buffer: flesh out docs for gst_buffer_make_writable() a little 
There is a similar explanation in gst_caps_make_writable, but the existing
documentation can be misleading since it does not define what 'is already
writable' means.

Also note when this function is meant to be used.

41e1bea7ef buffer: Add a GST_BUFFER_DTS_OR_PTS macro 
API: GST_BUFFER_DTS_OR_PTS

Many scenarios/elements require dealing with streams of buffers that
might have DTS set (i.e. encoded data, potentially reordered)

To simplify getting the increasing "timestamp" of those buffers, create
a macro that will return the DTS if valid, and if not the PTS

0f5be03d76 pad: Fix docs/annotation of gst_pad_probe_info_get_buffer_list()

G-I, leading to crashes because of broken ownership transfer.

45f0f354ac segment: Correct stream_time calc for negative applied rate 
Updated gst_segment_position_from_stream_time and gst_segment_to_stream_time to reflect correct calculations for the case when the applied rate is negative.

Pasting from design docs:

===============================
Stream time is calculated using the buffer times and the preceding SEGMENT
event as follows:

    stream_time = (B.timestamp - S.start) * ABS (S.applied_rate) + S.time

For negative rates, B.timestamp will go backwards from S.stop to S.start,
making the stream time go backwards.
===============================

Therefore, the calculation for applied_rate < 0 should be:

    stream_time = (S.stop - B.timestamp) * ABS (S.applied_rate) + S.time

and the reverse:

    B.timestamp = S.stop - (stream_time - S.time) / ABS (S.applied_rate)

2955eeb0ed bin: Make sure to free all cached messages when going to NULL 
An ASYNC READY->PAUSED might have failed without the bin code noticing during
the state change, in which case we will never get PAUSED->READY and would leak
messages.

4881d1c16c tracer: use GQuark or strings for the hook id 
This way one can define new tracing probes without changing the core. We are
using our own quark table, as 1) we only want to initialize them if we're
tracing, 2) we want to share them with the tracers.

1a3e218b89 tracer: simplify hook api
