3eb033bba2 mpegts: GST_EXPORT -> GST_MPEGTS_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

90b27a3c8b mpegts: Add padding to public structures
Allows use to add API in the future without breaking ABI. We broke the API/ABI
once between 1.2 and 1.4, let's try to avoid this in the future even if this
is an unstable library.

22dfd9aef3 mpegts: Unify API : GstMpegts / gst_mpegts_ / GST_*_MPEGTS_
It was previously a mix and match of both variants, introducing just too much
confusion.

The prefix are from now on:
* GstMpegts for structures and type names (and not GstMpegTs)
* gst_mpegts_ for functions (and not gst_mpeg_ts_)
* GST_MPEGTS_ for enums/flags (and not GST_MPEG_TS_)
* GST_TYPE_MPEGTS_ for types (and not GST_TYPE_MPEG_TS_)

The rationale for chosing that is:
* the namespace is shorter/direct (it's mpegts, not mpeg_ts nor mpeg-ts)
* the namespace is one word under Gst
* it's shorter (yah)

1cab60b713 mpegts: atsc: add atsc's EIT table parsing
ATSC has its own version of the EIT table (DVB also has one).

This patch adds parsing for the ATSC EIT table and also fixed
the section identification to mark it as the ATSC one.

The implementation aws refactored to reuse some common internal
structures from ETT.

Also adds its dumping function to ts-parser example

0c6bb561e0 mpegts: atsc: add STT table parsing
Adds the system time table structure and functions for convenient parsing of
it and for getting the UTC datetime that it represents. Also adds its
information dumping to the ts-parser example

7ced36eccd mpegts: atsc: add ETT structures and parsing
ETT (extended text table) contains ATSC text information with descriptions
of virtual channels and events. The text can be internationalized and also
compressed.

9eed28d353 mpegts: add atsc MGT section parsing
Add a parsing function for MGT and also detect the EIT tables
for ATSC, the EIT pids are reported inside the MGT and we are still
only relying only on the table id for detecting it. In the future we
would want to also check the pid and compare with whatever the MGT
previously reported to confirm that it is indeed the EIT.

8f6a3c0a99 mpegts: atsc: rename TVCT to VCT as it is the same as CVCT
Make the ATSC section parse handle both TVCT and CVCT as they are
nearly the same struct (CVCT uses 2 reserved bits that are ignored
in TVCT).

This is changing the glib type and the struct name but TVCT wasn't
released in a stable package yet so there should be no problem.

Also includes some parsing fixes and changes short_name to be
directly stored as utf8 rather than utf16

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.

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 :)

c1366efcd6 libs/mpegts: Rename GstMpegTS => GstMpegTs
Sorry for this :( But this makes it more in sync with expected type
naming in gobject (i.e. CamelCase and not CamelMAYBECase).

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).
