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
