7ba0c1b390 avutil: change GET_UTF8 to not use av_log2() 
This removes an inter-library dependency on ff_log2_tab causing
linking errors in some configurations.

8c0a3d5fe0 avutil: remove inline av_log2 from public API 
This removes inline av_log2 and av_log2_16bit from the public API,
instead exporting them as regular functions.  In-tree code still
gets the inline and otherwise optimised variants.

6c4975eaaf libavutil: add saturating addition functions 
Fixed-point audio codecs often use saturating arithmetic, and
special instructions for these operations are common.

6b34fbba9b MK(BE)TAG: avoid undefined shifts 
Casting the left-most byte to unsigned avoids an undefined
result of the shift by 24 if bit 7 is set.  This affects
the rm demuxer.

eb3755a5aa 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.
