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). https://bugzilla.gnome.org/show_bug.cgi?id=702724

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 :)

mpegts: Unify section checks and add BAT parsing * Avoid repeating code everywhere, and instead provide all parsing information in one go. * Add BAT support * Refine BAT/CAT identification (by adding PID checks)
