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.

ae4d6bb334 mpegts: Unify section checks and add BAT parsing
* Avoid repeating code everywhere, and instead provide all parsing
  information in one go.
* Add BAT support
* Refine BAT/CAT identification (by adding PID checks)

f3d53fcd97 mpegts: Avoid false-positives in section type detection
Due to the variety of section types out there, we need to add
some checks when identifying section types.

We check here that the PID is also consistent with the table_id.

d95bb48864 mpegts: Fix NIT parsing
The size checks were wrong. The smallest size for a NIT is 16 bytes
(12 for the smallest content + 4 for crc) and the smallest size for
a inner stream loop is 6 bytes (without any descriptors).

Also remove FIXME that has already moved elsewhere

34164610b0 mpegtsdescriptor: Fix handling of unknown stream encodings
If we cannot identify the encoding used for a string, return a NULL
string instead of garbage and add a FIXME so we can detect and later
fix it.

4fe26740c7 mpegts: Add registered mpeg-ts stream types
These are the values officially registered in the base specification
(H.222.0/13818-1). Later on we can add other enums for other variants

Note that the enum is not used in the structure fields (such as a pmt
stream stream_type field) since it can contain values from other
variants.

982aee25c6 mpegts: Split files and implement free functions
* In order to avoid future clashing between table_id for the various
  mpeg-ts variants, use different enums.
* In order to keep everything clean(ish) and allow for cleaner growth,
  split into different files (will need the same for descriptors later)
* Also ... implement free functions for all table types :)
