I was using some perf tools through checkasm when I noticed an awful
lot of time was spent calling av_isdigit() which was kind of silly,
and inlining it made it run around 5% faster overall. But yes, it's
obviously not a performance critical piece of code by any means. I
haven't really looked at other code that uses any of those functions
though.

av_toupper() and av_tolower() are similar short functions in the same
file that are currently inlined though, so one could argue that this
patch improves consistency if nothing else.
