cb97400f93 Revert "cmdutils: make use of new iteration APIs"
This reverts commit cdc78058c7.

It introduced several issues in the command line tools, and it's
implementing a new API that may still see some changes.
Revert for the time being until the state of the API is defined.

48bc9fffd1 id3v2: fix unsynchronization
The ID3v2 "unsynchronization scheme" requires replacing any 0xFF 0x00
sequences with 0xFF. This has to be done on every byte of the source
data, while the current code skipped a byte after a replacement. This
meant 0xFF 0x00 0xFF 00 was translated to 0xFF 0xFF 0x00 instead of 0xFF
0xFF. It feels a bit messy to do this correctly with the avio use. But
fortunately, this translation can be done in-place, so we can just do it
in memory.

Inspired by what taglib does.

Also see 9ae80e6a9c. (The sample file for
that commit is gone, so it could not be retested.)

3caecf7ce8 avcodec: do not use init_static_data on some codecs
They don't modify AVCodec, no needs to call it at register. They will be
wasteful if these codecs are unused. Instead, call static data initialization
at codecs' init.
