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 adapts and merges commit f4bf2363
from libav, originally skipped in 13a211e6
as it was not necessary back then.

Is's applied now in preparation for the following patches, where the
aac_adtstoasc bitstream filter will start to correctly propagate the new
extradata through packet side data.

Don't just look at zero sized packets, and also check for AAC extradata
updates, in preparation for the following patches.

If the source is using a custom IO, setting this flag causes heavy leaks
since the segments will not have their avio context closed.

Regression since f5da453b.

Using AVOnce as a stack variable makes no sense as the state is lost
when the function exits.

This fixes repeated calls to av(filter/device)_register_all
