avcodec/gifdec: Add av_log() to workaround gcc 4.2 miscompiling the code
...
It appears gcc forgets to increment the byte stream pointer at -O3
I was not able to spot a reason/excuse for it to do that. It
also disappears if the function isnt inlined.
This should fix the gif fate failures on open & free bsd

Prepare gif decoder for use in conjunction with gif demuxer.
...
Add capability of reading multiple frames instead of only first.
Implement support for different gif frame 'disposal methods'.
Add option that allows to change background color resulting from
conversion of gif with transparency to any other format which
not support it.
Also bump lavc minor version.

Add meaningful error codes and constants.
...
Replace literals with named constants in several pieces of code
like 'return -1' and 'case 0xab'.
Change the way decoder handles absence of image data in a file:
notify gif_decode_frame() caller with got_picture set to zero
instead of returning -1.
