Start code emulation prevention is only required in Annex B bytestream
packed NAL units. For other coding formats the size is already known.
Looking for a start code prefix can result in false positives like in
http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4
which has a false positive in the SPS.
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.

Currently, the parser is buggy and only processes the stream extradata
when the flag is set. This fixes it to actually inspect the frames.
Whitespce will be fixed in a separate change.

None of these symbols should be accessed directly, so declare them as
hidden.

The header is empty after making the function static, so delete it and
drop its usage.

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.

This allows freeing the parser memory in the thread_context freeing loop.

This ensures that the parser will no longer leak memory for all SPS/PPS it encounters.

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.
