  Remove an unused parameter from x264_slicetype_frame_cost()
  
  The b_intra_penalty parameter is no longer used anywhere after the
  improvements to the --b-adapt 1 algorithm.

  msvc: Add snprintf/vsnprintf replacements
  
  MSVC pre-VS2015 has broken snprintf/vsnprintf implementations which are
  incompatible with C99 and may lead to buffer overflows.

• Improve the —b-adapt 1 algorithm

  Improve the --b-adapt 1 algorithm
  
  Roughly the same speed as before but with significantly better results,
  comparable to --b-adapt 2.

  x86inc: Enable AVX emulation in additional cases
  
  Allows emulation to work when dst is equal to src2 as long as the
  instruction is commutative, e.g. `addps m0, m1, m0`.

  x86inc: Improve handling of %ifid with multi-token parameters
  
  The yasm/nasm preprocessor only checks the first token, which means that
  parameters such as `dword [rax]` are treated as identifiers, which is
  generally not what we want.
