demux: ts: rewrite, unifying by program

fixes #13967
* Recenters everything that depends on program: Time, timerolls, hacks...
* Removes PCR probing, programless timeroll handling
with a simplier fix (won't work with 2x26 hours recording, but..)
* Better probing of program duration (not based on inter PCR). More accurate,
at best by 1 frame length.
* Changes seek handling and bisects only on request (removes the whole file probing)
* No longer creates ES at preparse time
* Simplify/Unify dual program selection list and don't trust default program at first
* Many numerous other fixes
