Bump the minimum libvpx version to 1.3.0 and rework the configure logic
to fail only if no decoders and encoders are found.
Based on the original patch from Vittorio.

Patch to support VP9 encoding with new profiles 1-3.
Profile 1 (8-bit 422/444) should work with default libvpx
configuration.
However you will need to configure libvpx with
--enable-vp9-highbitdepth before building and linking
with ffmpeg for profile 2 (10-/12-bit 420) and profile 3
(10-/12-bit 422/444) encoding.
You may use the appropriate profile option on the
command line:
-profile:v 1 for 422/444 8-bit encoding
-profile:v 2 for 420 10-/12- bit encoding
-profile:v 3 for 422/444 10-/12-bit encoding
If you do not use the -profile:v option, it will be deduced
from the source format.

Default libvpx msvc buils used module definition to export symbols.
These symbols are exported as pointers to data which dont link when
referenced directly.

Currently, this option is accessed through AVCodecContext.mb_threshold,
which originally controlled reusing MB data when transcoding mpeg to
mpeg. Since the libvpx meaning is completely different from the original
mpegvideo meaning, it is better to use a separate private option for
this.
Changes in the parameter mapping for libvpx to support the constant
quality mode in VP9. The assumption in the patch is that if crf is
provided but bitrate is 0, then the 'constant quality' mode of VP9
is used. However if both are present, the 'constrained quality' mode
is used as before.
