8f4123a881 mpegts: fix sdt length check
It was originally test for 9 bytes (as the comment says) and was
rewritten buggily. So rewrite it a third way, which is now
hopefully consistent with the original and the comment, while
being more sense-making to humans.

224cb81b8f mpegts: test for allocation failure
While it's unlikely to get there, it silences the coverity warning
on the error code path that we test for NULL before freeing, when
all branches there are from locations where pmt cannot be NULL,
and removing the NULL check makes the code more vulnerable to a
hypothetical future branch from somewhere where it can be.

5d06aed3e2 mpegts: ABI/API break: Use GPtrArray instead of GArray
While it was a great idea, various g-i based bindings don't support
GArray with entries greater than sizeof(gpointer) :(

So let's just make everybody happy by just using GPtrArray.

And since we're breaking the API, also rename the various descriptor fields
to no longer have the descriptor_ prefix.

It does cost a bit more in terms of memory/cpu usage, but makes it usable
from bindings.

c1366efcd6 libs/mpegts: Rename GstMpegTS => GstMpegTs
Sorry for this :( But this makes it more in sync with expected type

Also split descriptor type enums into the different variants:
* ISO H.222.0 / 13818-1 (i.e. standard mpeg-ts)
* DVB
* ATSC
* ISDB
* miscellaneous

This will avoid future clashes when specs use the same descriptor type

3665e8543a gst-libs: New Mpeg-TS support library
Exposes various MPEG-TS (ISO/IEC 13818-1) and DVB (EN 300 468) Section
Information as well as descriptors for usage by plugins and applications.

This replaces entirely the old GstStructure-based system for conveying
mpeg-ts information to applications and other plugins.

Parsing and validation is done on a "when-needed" basis. This ensures
the minimal overhead for elements and applications creating and using
sections and descriptors.

Since all information is made available, this also allows applications
to parse custom sections and descriptors.

Right now the library is targeted towards parsing, but the structures
could be used in the future to allow applications to create and inject
sections and descriptors (for usage by various mpeg-ts elements).
