This returns the internal feature list cookie, which changes every
time a feature is added or removed. This can be used by elements
to check if they should update their cached feature lists.
This avoids:
* triple-checking for the GType when type-checking is enabled (see #597260)
* Avoids going through an expensive no-argument checking which landed in
glib-2.22
* Avoids going through 2 extrac functions (g_object_new -> g_object_new_valist)
There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.
This avoids having to do the sorting everytime we use typefind
The behaviour of gst_type_find_factory_get_list has subtlely changed
in the sense that the order was previously undefined, whereas now
it returns them sorted by rank and then by name.
Maintain a hashtable of the plugin basename. We can then use this
hashtable to speedup the search for an existing plugin and avoid
a whole lot of strcmp calls.
When the plugin-scanner load fails (because the helper can't be
spawned), make sure to load the plugin that failed in-process, so
that all plugins do get loaded.
Everyone running an uninstalled git setup is going to wonder about
this failure next time they update, so let's mention the solution
in the error message.
When updating the registry, we don't need to re-read the registry cache
and waste time replacing all our existing, hopefully identical, plugins
and features that we're about to re-scan anyway.
phase 2 - make the plugin loader receive the list of plugins to load and
send back the results asynchronously, so we don't context switch back
and forth so much.

* gst/gstregistry.c: (gst_registry_scan_path_level):
Don't recurse into .debug directories as some distros install
the debugging symbols next to the plugins in .debug directories
and dlopen() crashes on them sometimes. Fixes bug #508070.
Add FIXME for 0.11 to not recurse into directories at all because
it's very inconsistent to the behaviour of other PATH environment
variables.

* gst/gstregistry.c: (gst_registry_add_feature):
When replacing an existing feature in the registry, make sure to
continue holding a reference until we've replaced the name string
within our feature hash table. Make sure to use g_hash_table_replace
instead of g_hash_table_insert to ensure the new name string is used
as a key instead of the old one that we're about to free.
