Based on code from Carl Eugen Hoyos, Michael Niedermayer and Paul B Mahol.

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.

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

The loops were reading ahead one line, which could end up outside the
buffer for reference blocks at the edge of the picture.  Removing
this readahead has no measurable performance impact.

exp files are created in every build and contain export information
of the libraries. Both pdb and ilk are created during debug builds,
and contain linking and debug information used by MSVC.

Internally chroma planes have multiple of four height while allocated image
planes might be smaller if CODEC_FLAG_EMU_EDGE is set. Thus we should not
output more lines of chroma than frame can accept.

Also the decoder can be safely switched to direct rendering now.

The compiler/linker flags passed to check_lib2 should not be quoted.

aac_tablegen.h includes aac.h for the POW_SF2_ZERO definition, but
this also pulls in a raft of other headers, some of which are not
safe to use in code built with the host compiler.

Moving POW_SF2_ZERO to aac_tablegen_decl.h, where the declaration
of the array it relates to already resides, fixes the problems.
