mpeg-ts changes v2

A new suggestion to the changes in mpeg-ts lib.

The changes supports the NIT table. I have tested it by creating a NIT section
with a network name descriptor.
The flow is outlined below

- A GstMpegTsNIT is created using the new lib function
  GstMpegTsNIT *gst_mpegts_section_new_nit (void);

- Top level fields (network_id, and actual_network) is set

- A GstMpegTsDescriptor is created using new lib function
  GstMpegTsDescriptor *gst_mpegts_descriptor_from_dvb_network_name (const gchar
*name)

- The descriptor is added to the GstMpegTsNIT descriptor field

- A GstMpegTsSection is created by the new lib function
  GstMpegTsSection *gst_mpegts_section_from_nit (GstMpegTsNIT *nit);

- The GstMpegTsSection is injected into the muxer using the new lib function
  guint8 *gst_mpegts_section_packetize (GstMpegTsSection *section, gsize
*output_size);

I don't like the *_new_nit* functions that well (guess they also would require
a free function). Am I missing some GLib magic that can help us there?
