9f61abc811 lavf: allow custom IO for all files 
Some (de)muxers open additional files beyond the main IO context.
Currently, they call avio_open() directly, which prevents the caller
from using custom IO for such streams.

This commit adds callbacks to AVFormatContext that default to
avio_open2()/avio_close(), but can be overridden by the caller. All
muxers and demuxers using AVIO are switched to using those callbacks
instead of calling avio_open()/avio_close() directly.

(de)muxers that use the URLProtocol layer directly instead of AVIO
remain unconverted for now. This should be fixed in later commits.

7ccedc1c78 avformat/img2dec: do not interpret the filename by default if a IO context has been opened 
With this, user applications which use custom IO and have set a IO context will not have
their already opened IO context ignored and glob/seq being interpreted

Comments and tests from maintainers of user apps are welcome!

ce70f28a17 avpacket: Replace av_free_packet with av_packet_unref

a drop in replacement.

26e8895b73 all: add _DEFAULT_SOURCE locally wherever needed 
Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE.
The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros.
This solution is on the lines of the one in commit af1818276e.

bmp pipe needs the bmp parser which is not bug free and should thus not be favored
over the bmp image2 demuxer
that also means this change could be reverted in case bmp pipe is improved so it
