This patch adds the basic infrastructure to have openCL acceleration.
For now only YUV2RGB is implemented but other operations could be
implemented.
The primitives have been massively reworked so that we have an autodetect
mode that will pick the best implementation automatically by performing a
benchmark.

Some encoder/decoder formats are currently not really working or
have not been thouroughly tested. To allow fearless hackers
fine tuning this flag is added to easily enable/disable these formats.
The sound and microphone redirection channels (and in part TSMF)
did not properly decouple encoding/decoding from the backends used
to play/record sound.
Encapsulating encoding/decoding in rewritten freerdp_dsp_* functions
with variable backends, simplifying alsa/oss/pulse/... audio backends.
Leverages libavcodec's hw decode support to provide VA-API based
hardware decoding. Depends on the local build of ffmpeg having hardware
VA-API support compiled in and the appropriate libva drivers and
libraries installed.
SDK 10.13 (and possibly olders as well) need HAVE_UNISTD_H to be set to
a value if available otherwise the following error is thrown:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include/dispatch/dispatch.h:38:45:
error: expected value in expression #if !defined(HAVE_UNISTD_H) || HAVE_UNISTD_H
- fixed invalid, missing or additional arguments
- removed all type casts from arguments
- added missing (void*) typecasts for %p arguments
- use inttypes defines where appropriate
build-config.h should contain configure/compile time settings that are
relevant for projects that use FreeRDP.
For example the compiled in plugin search paths.
uClibc variants do not provide the C99 long double math functions like ceill,
powl, etc.. For future compatibility use check_symbol_exists() to check
whether these functions are available, and keep the result in
HAVE_MATH_C99_LONG_DOUBLE. Use that instead of the fragile Cygwin version
check in triodef.h.
Fixes build failures under uClibc(-ng) like:
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `powl'
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `fmodl'

../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `floorl'

uClibc master branch, as well as uclibc-ng add eventfd_{read,write}
definitions. Instead of testing for __UCLIBC__, have cmake explicitly check
for the existence of eventfd_read and save the result in
WITH_EVENTFD_READ_WRITE.
Fixes build errors like:
