This is not based on lucas work due to code divergence (its less work this way
than trying to merge from a split based on 2 years outdated code)

The libav code depends on mp3 startcodes only occuring at the start of
frames. But there is nothing in mp3 that prevents them occuring elsewhere
by chance. Thus the code would fail randomly, the new code searches for 3
consecutive valid frames. If this turns out to be still insufficient the
number can be raised further, or additional checks added.

Earlier versions of for instance of libavcodec expect this symbol to be
present in libavutil. This commit can be reverted after the next major
bump.

New shared builds of avcodec will link to the internal copy of the
table within that library, so those builds won't rely on this table
being present in avutil any longer either.

These tables are used for instance by older versions of libavcodec and
need to remain visible until the next SONAME bump.

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.

This name is more descriptive as the function returns a fixed-point
value with 15 fraction bits.

Avoid to divide num and den by gcd in case of a parsed expression, since
that is already done in av_d2q(), and force reduction in case of "a:b"
form, allowing to honour the max parameter.

The latter change is consistent with the a/b case, and with the
documentation.

This avoids some duplication when listing and testing for the functions.
