Useful for debugging.

Avoid code duplication.

Due to it in contrast to the decoder not setting up low_delay,
the code in parse_nal_units would always end up setting has_b_frames
to 1 (except when stream is explicitly marked as low delay).
Since the parser itself would create extradata, simply reopening
the parser would cause this.
estimate_timings_from_pts would cause the parser to be reopened
on the same stream.

This fixes trac issue #360.

Correct computation of implicit weight tables when referencing pictures

The current check on MMCO parameters prohibits a "max long term frame index
plus 1" of 16 (frame idx of 15) for the "set max long term frame index" MMCO.
Fix this off-by-one error to allow the full range of legal values.
