Some compilers are very intuitive, and others are not so much, so let's
pre-compute the variables e and keylen outside the for loop. Ensuring a
minor speed increase regardless of if compiler is smart enough to solve
this improvement for itself, or not.

If we test for {0..9} first, we have tested for 10/16th of all possible
characters first and avoid testing the remaining 6/16th of all possible

Replace av_isxdigit(*ptr) and convert(*ptr) with get_nibble(*ptr) which
returns a valid nibble=={0x00..0x0f} or false==255 for all other values.
This way we only need to work with *ptr once instead of twice.
Removing inline av_isxdigit(x) functions also shrinks executable size.

Minor speed increase, end is calculated before entering parse_str_int(),
so let's take advantage of the value and avoid recalculating twice more.
This also allows parse_str_int() to work with file size larger than int.

After some further thought and discussion on the FFmpeg and Xiph.org IRC
channels, the current behavior seems reasonable. To my knowledge, PAL8 is
guaranteed to have exactly 256 colors. This is why, somewhat surprisingly,
GIFs aren't decoded as PAL8, they're decoded as BGRA. This means that they

Thanks, looking now !
That's true, but as far as I can tell FFmpeg assumes that all paletted
images have 256 colors, and thus there isn't a way to get the exact number
of colors in a GIF.
I also doubt that this will cause problems in practice, it's somewhat
strange that this field is even there.

Is this correct, though?
GIFs encoded by things that are not libavcodec may have less than
AVPALETTE_COUNT entries/colors.
