Typing hints can only be passed to gst_value_deserialize()
through the type of the passed-in value. This means deserialization
can only target the desired type for the top-level elements,
making it for example impossible to deserialize an array of
flags to the expected type.
This commit exposes a new function, gst_value_deserialize_full(),
that takes an optional pspec as the extra parameter, and updates
the deserialization code to pass around that pspec, or the
element_spec when recursively parsing the elements of a list-type
value.
This allows for example passing arrays of flags through the
command line or gst_util_set_object_arg, eg:
foo="<bar,bar+baz>"

... 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.

Custom meta is backed by a GstStructure, and does not require
that users of the API expose their GstMeta implementation as
public API for other components to make use of it.
In addition, it provides a simpler interface by ignoring the
impl vs. api distinction that the regular API exposes.
This new API is meant to be the meta counterpart to custom events
and messages, and to be more convenient than the lower-level API
when the absolute best performance isn't a requirement.

Subsequent lookups in the hashtable are probably better done
on memory we're confident is allocated to us :)
It was easy to trigger invalid reads by calling gst_meta_register
with dynamically allocated memory, freeing that memory, then
calling gst_meta_get_info()

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

The global seqnum variable wasn't actually increased in
the fallback code path, leading to all buffers getting
a seqnum of 0. Which also made the unit test fail.
This affects platforms/toolchains that don't have
64-bit atomic ops such as when compiling for armv7 rpi.

For providers that don't support dynamic probing, just fall back to doing
a static one on start() to make the UI developers life easier.
This also means that the monitor doesn't need to call _can_monitor() before
calling start.

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.

Otherwise the proxy pad of the ghost pad still stays linked to some
element inside the bin, which is not allowed anymore according to the
topology.
In 2.0 this should be fixed more generically from inside GstGhostPad but
currently there is no way to get notified that the ghost pad is
unparented.

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.

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.

These can be passed to gst_type_mark_as_plugin_api, to inform
plugin cache generation.
For now a single flag is specified, "IGNORE_ENUM_MEMBERS", it
can be used for dynamically generated enums to avoid documenting
environment-specific enumeration members. An example is
GstX265EncTune.
