5195ad9126 gsturi: Add new API for storing unmodified userinfo / fragment
New API: gst_uri_from_string_escaped()

Identical to gst_uri_from_string() except that the userinfo and
fragment components of the URI will not be unescaped while parsing.

This is needed for correctly parsing usernames or passwords with `:`
in them such as reported at:

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()

Might also help a bit with #424

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.

63c1945695 ghostpad: Deprecate gst_ghost_pad_construct()
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.

initialization once, do it every time the clock time is requested.

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.

c4a2d92718 systemclock: Get rid of atomic access to clock entry status and use the mutex instead
We already have a mutex in each clock entry anyway and need to make use
of that mutex in most cases when the status changes. Removal of the
atomic operations and usage of the mutex instead simplifies the code
considerably.

The only downside is that unscheduling a clock entry might block for the
time it needs for the waiting thread to go from checking the status of
the entry to actually waiting, which is not a lot of code.

3e924f5df9 systemclock: Don't start waiting for a clock id if it was signalled before
Otherwise it can happen that unscheduling a clock id never takes place
and instead it is waiting until the normal timeout. This can happen if
the wait thread checks the status and sets it to busy, then the
unschedule thread sets it to unscheduled and signals the condition
variable, and then the waiting thread starts waiting. As condition
variables don't have a state (unlike Windows event objects), we have to
remember ourselves in a new boolean flag protected by the entry mutex
whether it is currently signalled, and reset this after waiting.

Previously this was not a problem because a file descriptor was written
to for waking up, and the token was left on the file descriptor until
the read from it for waiting.
