This contains encoder wrappers for H264, HEVC, AAC, AC3 and MP3.

This is based on top of an original patch by wm4
<nfx...@googlemail.com>. The original patch supported both encoding
and decoding, but this patch only includes encoding.

The patch contains further changes by Paweł Wegner
<pawel.wegne...@gmail.com> (primarily for splitting out the encoding
parts of the original patch) and further cleanup, build compatibility
fixes and tweaks for use with Qualcomm encoders by Martin Storsjö.

This allows access to the HW video encoder on Windows on ARM64
on Qualcomm platforms. However, to actually use that, one has to
manually choose nv12 as input pixel format, otherwise the encoder
format negotiation fails.

I've tried to read up on the feedback this patch got the earlier
times it was posted and address those issues. In particular,
this is enabled automatically if suitable headers are available.
The built binary still runs on Vista (even if the required MF
functionality isn't available there).

Building succeeds with MSVC, old and new mingw-w64 toolchains,
and isn't detected nor enabled on mingw.org toolchains. The configure
check looks for one of the API details used; mingw-w64 versions
from before that feature was added won't try to build the code,
while newer ones should have enough features to build it successfully.

Missing docs update.

Which one is mandatory here? I added a changelog entry locally now as wel. I guess it could have short general description in doc/encoders.texi, or does one have to duplicate the info about all the options as well?
