This removes the current API violating behavior of overwritting the stream's
extradata during packet filtering, something that should not happen after the
av_bsf_init() call.
The bitstream filter generated extradata is no longer available during
write_header(), and as such not usable with non seekable output. The FATE
tests are updated to reflect this.

This makes the currently semi-public avpriv_aac_parse_header() function
private to libavcodec and adds a proper public API function to return
the parts of the ADTS header required in libavformat.
The function currently accepts a PutBitContext and a GetBitContext,
which hardcodes their sizes into the lavc ABI. Since the function is
quite small and only called in a few places, the simplest solution is
making it inline, thus avoiding a runtime dependency completely.

ASC frames smaller than AAC_ADTS_HEADER_SIZE were being discarded.

Some invocations include a verb in the log message, others do not. Yet
av_log_missing_feature expects callers to provide a verb. Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.
None of these symbols should be accessed directly, so declare them as
hidden.

(cherry picked from commit d36beb3f69)
The AAC decoder and ADTS-to-ASC BSF both require the header decoder
but not full parsing capabilities.
