0d1fad0e92 pad: clear probes holding mutex
Protect clearing probes against concurrent modification which might happen
due to dispose does NOT guarantee that the object is not used anymore, as
it could be referenced again and so being continued used.
So, as in the rest of places where probes hook list is used, on dispose
it should be accessed holding the mutex "GST_OBJECT_LOCK (pad);" as
GHookList is not thread-safe.

93e6261db7 systemclock: Update monotonic reference time when re-scheduling
There is no guarantee that the clock is currently advancing, therefore if we
re-schedule (because of timeouts) a clock wait, we need to re-acquire the
current monotonic clock value against which we will wait.

Avoids spinning the cpu like mad (due to constant timeout) when clocks are
PAUSED.

Fixes #673

e231f1d3af gstinfo: colorize PIDs in log messages
The PIDs on log lines were supposed to be colorized before, but the
escape sequence was incorrect.  With this change, the code uses the
correct sequence to colorize those PIDs.  E.g., instead of `\033[334m`
(incorrect), use `\033[34m` (correct).

This makes the log messages easier to read.  It also reduces the chance
that a buggy terminal will choke on the invalid escape sequence.

ca4edf6741 info: Load DbgHelp.dll using g_module_open()
... and update meson file so that enable it only using required headers.

"dependency(...)" is unlikely successful for Windows SDK libraries
since it doesn't ship pkg-config file. So it needs to be changed
to "find_library()" to link corresponding .lib file. That would
result to most MSVC build system will link dbghelp.dll. However,
one drawback of the change is that gstreamer-1.0.dll will mandate
dbghelp.dll although it should be optional. So g_module_open() way
can be the most safe way in this case.

e4f7cdb0df tracer: declare GstTracer API stable
It's been around for more than 4 years and people have built
lots of stuff on top of it, doesn't really make sense to keep
it marked as unstable. We're unlikely to change it now, and
we can always deprecate it and make a new one if needed.

This stabilises the following API:
- gst_tracer_register()
- gst_tracing_get_active_tracers()
- gst_tracing_register_hook()
- gst_tracer_record_new()
- gst_tracer_record_log()

3cfda6d6eb gstelementfactory: Fix missing features in case a feature moves to another filename
In case a plugin filename was renamed with the plugin being in the registry cache
the features were not loaded after the rename:

1) Cache of old/gone filename was loaded, features added
2) New filename was loaded, features where not added because
   they were already found in the registry.
3) In the end stale cache entries for files which are no longer there
   are removed, including the wanted features.
4) The cache gets updated without the features.

Fix this by also checking at (2) that the found feature is from the loaded plugin
and not from some stale cache entry.

This affected directsoundsink where libgstdirectsoundsink.dll was renamed
to libgstdirectsound.dll, losing the directsoundsink element in the process.

1206a60bac bus: clear bus->priv->signal_watch immediately when the source is removed
There is a race-condition that can trigger the assertion in
gst_bus_add_signal_watch_full():

If gst_bus_add_signal_watch_full() is called immediately after
gst_bus_remove_signal_watch() then bus->priv->signal_watch may still be set
because gst_bus_source_dispose() or gst_bus_source_finalize() was not yet
called.
This happens if the corresponding GMainContext has the source queued for
dispatch. In this case, the following dispatch will only unref and delete
the signal_watch because it was already destroyed. Any pending messages
will remain until a new watch is installed.

So bus->priv->signal_watch can be cleared immediately when the watch is
removed. This avoid the race condition.

Instead do everything it did as part of GObject::constructed() and
change the function to always return TRUE.

gst_ghost_pad_construct() was meant to be called by subclasses right
after construction of the object to finish construction as it can fail
in theory. In practice it's impossible for it to fail, even more so if
called directly from GObject::constructed(): The only failure condition
is if the newly created proxy pad already has a parent, which is
impossible at this point as nothing else can have a reference to it.

31e6d766ff gst: Delay creation of threadpools
Since glib 2.64, gthreadpool will start waiting on a GCond immediately upon
creation. This can cause issues if we fork *before* actually using the
threadpool since we will then be signalling that GCond ... from another process
and that will never work.

Instead, delay creationg of thread pools until the very first time we need
them. This introduces a minor (un-noticeable) delay when needing a new thread
but fixes the issues for all users of GSTreamer that will call gst_init, then
fork and actually start pipelines.
