avcodec: Rename avpriv_frame_rate_tab to ff_mpeg12_frame_rate_tab
...
This table doesn't need to be shared with libavformat any longer.
Add mpeg12 to the name to make it less ambiguous, while renaming it.

mpeg2videodec: fix list of supported frame rates to include sane ext rates.
...
This only adds a subset of the frame rates that can be stored, a full list
would be more than 500 entries. Such full list could (and should) be added
if it has a usecase but the number of users of even the now added rates
seem rather small.

...
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
