programs using ffmpeg that are compiled with -Wshorten-64-to-32
gives a warning when using header files common.h and rational.h

cast 64-bit truncated values to (uint32_t) to avoid the warning

Make sure the behavior does not change with the locale.

As far as I can tell the code should not change behaviour
depending on locale in any of these places.

This code cannot use av_assert* due to circular header dependancies

This removes an inter-library dependency on ff_log2_tab causing
linking errors in some configurations.

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.

It is only used in that library.

Fixed-point audio codecs often use saturating arithmetic, and
special instructions for these operations are common.

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.

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.
