f76d1a2514 mpegts: remove storage of never used values
Both _parse_atsc_mgt() and  _parse_atsc_vct () change the value of the variable
data just before returning. The new value is never used since data is a pointer
declared at the beginning of the function and going out of scope just after the
new value is stored.

66c38b50f3 mpegts: Don't confuse slice allocator with regular one
Previously selector_bytes and private_data_bytes were sometimes allocated and
free using the normal allocator and sometimes using the slice allocator.
Additionally prefer g_strdup() to g_memdup() for strings.

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

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
