avformat/img2dec: Use avformat probing interface to identify format if it has not been otherwise identified

This is used only for distinguishing .pix formats for now.
Which is the only case that has image2 demuxers currently

Without this exception files with ".gif" extension by default
recognized as input suitable for image2 demuxer rather than gif.
In order to pass image through gif demuxer it was necessary
to use -f gif option.
This change affected 'make fate' test results because previously
image2 demuxer and gif decoder took only first frame of multiframe
test data, which is no longer true with gif demuxer.

Also introduce local img_ namespace to simplify debugging.

This allows decoding of concatenated frames encoded in
uncompressed formats like v210.
The frame size cannot be generally calculated, FFmpeg
also supports broken encoders.

Fixes ticket #1869.

Fixes CID703626.

Allow to override the default 'glob_sequence' value, which is deprecated
in favor of the new 'glob' and 'sequence' options.

The new pattern types should be easier on the user since they are more
predictable than 'glob_sequence', and do not require awkward escaping.

Take the new parameter start_index into account.
