741ff6a371 gstutils: Fix linear regression comparision
The check for dropping precision was wrong when sxx and syy were negative.

if they are negative then "G_MAXINT64 - val" would always overflow

The check was meant to use G_MININT64 (like in the loop contained just
after).

3afc575062 check: add missing harness function to symbol export list
Fixes in user code:

undefined reference to `gst_harness_add_element_sink_pad'

Also reorder harness function list to be strictly in alphabetical order and
double check the list with:

awk '{ if ($1 !~ /#define/) if ($2 ~ /gst_harness_/) { print $2 }; if ($3 ~ /gst_harness_/) { print $3} }' libs/gst/check/gstharness.h | sort

`./configure --disable-gst-tracer-hooks` didn't do anything, hooks were
always enabled regardless of the option. It works correctly in the

512cec3dea pad: gst_pad_activate_mode() always succeed if same mode
Checking that the pad is in the correct mode before the parent is
checked makes the call always succeed if the mode is ok.

This fixes a race with ghostpad where gst_pad_activate_mode() could
trigger a g_critical() if the ghostpad is unparented while the
proxypad is deactivating, for instance if the ghostpad is released.
More specifically, gst_ghost_pad_internal_activate_push_default()'s
call to gst_pad_activate_mode() would fail if ghostpad doesn't have a
parent. With this patch it will return true of mode is already
correct.

7ea4152323 gstvalue: allocate slightly larger than needed tables at startup
If we pre-allocate only *exactly* as many nodes as we need for the
core types, we are practically guaranteed a re-alloc when external
code like GstVideoTimeCode or GstEncodingProfile register their
own GstValue things. So allocate a bit more than strictly needed.

86abf49c23 gst: add a promise object
An object that can be waited on and asked for asynchronous values.

A callback can be installed for when the promise changes state.

d915dd4b20 gstpad: Make pad (de)activation atomic
The following could happen previously:
* T1: calls gst_pad_set_active()
* T2: currently (de)activating it
* T1: gst_pad_set_active() returns, caller assumes that the pad has
  completed the requested (de)activation ... whereas it is not
  the case since the actual (de)activation in T2 might still be
  going on.

To ensure atomicity of pad (de)activation, we use a internal
variable (and cond) to ensure only one thread at a time goes through
the actual (de)activation block

80262013ca gstpad: Make calls to GstPadActivateFunction MT-safe
checking whether we already were in the target GstPadMode was being
done too early and there was the risk that we *would* end up
(de)activating a pad more than once.

Instead, re-do the check for pad mode when entering the final pad
(de)activation block.

f03443f90c concat: Handle single-pad use-cases
When EOS reaches concat, it will switch to the next candidate as its
activate pad.

The problem arises when there is only one sinkpad, the "active" pad
becomes NULL. This results in concat becoming unusable after it receives
a *single* EOS on its single sinkpad.

If we detect there is a single sinkpad and there is no current active pad:
* If we are waiting (from selected sink event/buffer), become the current
  active pad.
* If there is a seek request, send it upstream. We don't switch the
  active_sinkpad property at that point in time, since the seek could
  fail. If the seek succeeds, the following SEGMENT (or STREAM_START)
  will cause the pad_wait() to elect that pad as the new active one.
* Flush events get forwarded

d106390adc element: add gst_element_foreach_*pad()
Add convenience API that iterates over all pads, sink pads or
source pads and makes sure that the foreach function is called
exactly once for each pad.

This is a KISS implementation. It doesn't use GstIterator and
doesn't try to do clever things like resync if pads are added
or removed while the function is executing. We can still do that
in future if we think it's needed, but in practice it will
likely make absolutely no difference whatsoever, since these
things will have to be handled properly elsewhere by the element
anyway if they're important.

After all, it's always possible that a pad is added or removed
just after the iterator finishes iterating, but before the
function returns.

This is also a replacement for gst_aggregator_iterate_sink_pads().

41e35c334b latency-tracer: Exclude synchronization time
The goal of this tracer is to measure the processing latency between a
src and a sink. In push mode, the time was read after the chain function
have returned. As the amount of time we wait to get synched is reverse
to the amount of latency the source introduced, the result was quite
surprising.

This patch moves the latency calculation in the pre-push hook. When
there is no processing in a a pipeline (e.g. fakesrc ! fakesink), the
latency will now be 0 as it's supposed to. For pull mode, the code was
already correct. When GstBaseSink operate in pull mode, the processing
time is done durring the pull, so pull-post is the right hook. The
synchronization will happen after the pull has ended. Note that
GstBaseSink rarely operate in pull mode.
