This adds a binding friendly interface to get and set arrays
and list into GstStructure.
New API:
- gst_structure_set_array
- gst_structure_set_list
- gst_structure_get_array
- gst_structure_get_list

When registering GstParamSpecArray, use the gst_value_array_get_type()
function to get the type, rather than the GST_TYPE_ARRAY macro, which
gets it from the _gst_value_array_type, which is in turn only
initialised during gst_init()
Fixes criticals with (python) bindings that look up all the
types from the gobject-introspection info as soon as they
are imported.

If guessing that a string matches a flagset, be more thorough
at checking that the string following a string of hex:hex:
actually looks like a flag set string. Add some unit tests
to catch more cases.

But only when serializing outside of GstStructures, because in case of
GstStructure the type is already preprended to the array/list and the
GstStructure API makes sure that they have the same "generic" type so
deserialization works properly.
This keeps serialization of GstStructures the same as before, and the
GstCaps unit tests already test for that. However when serializing
standalone arrays/lists get the types added now.
This can easily deadlock if the element uses the object lock for
something internally, like posting an error message. Use an GstIterator
for iterating over the pads instead.

When registering a new debug category after _debug_init(), we need to
re check the GST_DEBUG filter settings again.
In addition when parsing the filter setting, we need to already bump up
the min-debug level to not suppress debug log statments that dynamically
register a category. This happens in libraries that use a function to
register a category on first use.
A property not defined in a preset file can simply mean that the
user wants it to be set as it default value, and we should not warn
about that.
A missing preset file in a directory can happen has there are several
directory where a preset can be found in.
Saves us a custom script. Template files are nicer than passing
multiline templating stuff through to glib-mkenums. And we can
get rid of our custom python script.
It's a programming error to pass other pads here, and it easily causes
crashes or other problematic behaviour down the road as subclasses
usually assume to only get their pads.
Allows proper usage of structures in structures in caps. Subtraction
is not implemented due to complications with empty fields representing
all possible values.
The only implementation that doesn't delegate to the already existing
GstStructure functions is the union function.
