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.

d07b51bf07 aviobuf: Handle a NULL buffer in avio_close_dyn_buf 
This simplifies proper error handling in rtsp.c/rtspdec.c. When
broadcasting over RTSP in TCP mode, the AVIOContext is closed and
recreated for each sent packet, and if the recreation fails, we might
try to close a NULL buffer when freeing things at the end.

Previously, if recreating the buffer in rtspdec.c failed, this would
crash later due to trying to close a NULL buffer.

When av_reallocp fails, the associated variables that keep track of
the number of elements in the array (and in some cases, the
separate number of allocated elements) need to be reset.

Not all of these might technically be needed, but it's better to
reset them if in doubt, to make sure variables don't end up
conflicting.
