7a4abe5912 mpeg4video: ignore broken GOP headers
Some MPEG4 cameras produce files with empty GOP headers.
This patch makes the decoder ignore such broken headers and proceed
with the following I-frame.  Without this change, the following
start code is missed resulting in the entire I-frame being skipped.

3e2a4e91bd logging: downgrade recoverable errors to warnings
In all 3 cases, the decoding continues and thus a warning would be sufficient.
Helps application that catch them with own log handers to handle them
accordingly.

e7e2df27f8 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.
None of these symbols should be accessed directly, so declare them as
hidden.

91d51ee4b5 Remove redundant checks against MIN_CACHE_BITS
With the removal of the libmpeg2 bitstream reader, MIN_CACHE_BITS
is always >= 25, so tests against smaller values can be removed.
