0d4b8a2c16 hls: read protocol options through the AVIOContext
This reverts commit 9f9ed79d4c.

The hlsopts member was never set anywhere and always NULL, furthermore
the HLS demuxer needs to retrieve the proper options from the underlying
http protocol (cookies, user-agent, etc), so a dummy context won't help.

Instead, use the AVIOContext directly to access the options.

1dba8371d9 avformat: add protocol_whitelist
Note to maintainers: update tools

Note to maintainers: set a default whitelist for your protocol
If that makes no sense then consider to set "none" and thus require the user to specify a white-list
for sub-protocols to be opened

Note, testing and checking for missing changes is needed

dc87758775 avio: fix potential crashes when combining ffio_ensure_seekback + crc
Calling ffio_ensure_seekback() if ffio_init_checksum() has been called
on the same context can lead to out of bounds memory accesses and
crashes. The reason is that ffio_ensure_seekback() does not update
checksum_ptr after reallocating the buffer, resulting in a dangling
pointer.

This effectively fixes potential crashes when opening mp3 files.

3c18a7b188 avio: Do not consider the end-of-buffer position valid
Trigger a refill if the seek action moves the pointer
at the end of the buffer.

Before this patch the read action following the seek would trigger
the refill, while write action would write outside the buffer.

In the Libav codebase few muxers seek forward outside of what
already has been written so it is quite unlikely to experience
the problem with the default buffer size.
