      Make ff_inverse stay with libavutil, and optional copy it to libavcodec. · 3fc548df
      Diego Pettenò authored
      The ff_inverse table is used by FASTDIV macro, defined in libavutil, but up
      to now the table was defined only in libavcodec.
      After this change, the main copy of ff_inverse is part of libavutil (just
      like FASTDIV), but if CONFIG_SMALL is unset, then a different copy is made
      available to libavcodec, to avoid the performance penalty of using an
      external look up table.
      Dynamic linking works, because the libraries are linked with -Bsymbolic, so
      the local copy of the symbol has priority over the external; static linking
      works because the table is on a standalone object file in both libraries,
      so the linker is able to discard one of the two.
      Tested on Linux/x86-64 and Mac OS X/x86-64.
