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

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

ETT (extended text table) contains ATSC text information with descriptions
of virtual channels and events. The text can be internationalized and also
compressed.

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.

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

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.
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.
* 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 :)
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
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).
