multimedia/libvpx: update 1.6.0

ABI is incompatible... or not? SONAME has changed but the removed vp10
symbols weren't actually exposed (and still aren't).

Note, FreeBSD 9.x now builds with Clang 3.4 because GCC 4.2 fails:

  vp9/encoder/x86/vp9_frame_scale_ssse3.c: In function 'eight_tap_row_ssse3':
  vp9/encoder/x86/vp9_frame_scale_ssse3.c:93: internal compiler error: in simplify_binary_operation_1, at simplify-rtx.c:2563
  Please submit a full bug report,
  with preprocessed source if appropriate.
  See <URL:http://gcc.gnu.org/bugs.html> for instructions.

-Subject: vp9/10: fix encoder crash on flush
-
-the lookahead buffer allocation is deferred to receipt of the first
-frame to allow profile changes. if the encoder was flushed before
-supplying any frames the encoder would crash trying to dereference the
-NULL buffer. vp8 is unaffected.
-
-fixes mozilla bug:
