88d55b827d Remove incorrect use of ctype.h functions.
As far as I can tell the code should not change behaviour
depending on locale in any of these places.

This removes inline av_log2 and av_log2_16bit from the public API,
instead exporting them as regular functions.  In-tree code still

545dc699f8 Force inlining of avutil common routines
On some versions of gcc, these weren't always getting inlined due to hitting
the inline cap limit in some files.  This is generally bad, as most of these
functions are smaller inlined than not.
