Improve mpeg PS support

Adds support for MPEG-1 PS, HDDVD EVOB, and video codecs other
than mpeg1/2 in PS

Improves probing of unknown stream types by using Libav's probing
utilities

Use Libav to probe for dts profile in TS and PS files when profile is
unknown

Improves framerate detection (improved telecine detection)

Fixes preview generation for mpeg video that has only a single sequence
header

Patches Libav to handle VC-1 pulldown flags properly

Improve PS and TS stream log information
