Should prevent some options from being added to cflags when they
don't exist and the compiler only warns about it.

The library has several dependencies that vary between systems.
Their pkg-config properly lists them all.

Two of them are missing it in their pkg-config file, so adding it
here is a workaround until said pkg-config files are fixed.
Debugged with the help of Reino Wijnsma.

libxavs may require pthreads and libm at link time, and without
said ldflags available as global extralibs, the check will fail.

Remove the SDL_main define from the global cflags but not from the
ffplay cflags, and the -mwindows linker option from extralibs instead
of overriding it with the addition of -mconsole.

This reverts commit c2d155e11e.
GCC 6 incorrectly passes the configure test and then logs many warnings
of the form:
src/libavformat/dump.c: At top level:
cc1: warning: unrecognized command line option ‘-Wno-bool-operation’
Revert back to the test as done by commit af7a75cb51,
where it was changed to compile and not just preprocess to fix build failures on
FreeBSD with gcc 4.7

This adds hardware decoding for H.264 / HEVC / VP8 / VP9 using the MPP
Rockchip API. It returns frames holding an AVDRMFrameDescriptor struct
in buf[0] that allows drm / dmabuf usage. Tested on RK3288 (TinkerBoard)
and RK3328.

Support for this device has been removed in kernel since v2.6.37. dv1394 has been superseded by libiec61883 which is functionally equivalent.

This reverts commit 740e557d6e, reversing
changes made to 932e28b13e.
The commit apparently broke builds with shared libs, and "suggesting"
the use of external libraries that need to be explicitly enable has
dubious usefulness anyway.
This patchset enhances Alexis Ballier's original patch and validates
it using Qualcomm's Venus hardware (driver recently landed upstream
[1]).
This has been tested on Qualcomm's DragonBoard 410c and 820c
Configure/make scripts have been validated on Ubuntu 10.04 and
16.04.
Tested decoders:
- h264
- h263
- mpeg4
- vp8
- vp9
- hevc
Tested encoders:
- h264
- h263
- mpeg4
Tested transcoding (concurrent encoding/decoding)
Some of the changes introduced:
- v4l2: code cleanup and abstractions added
- v4l2: follow the new encode/decode api.
- v4l2: fix display size for NV12 output pool.
- v4l2: handle EOS (EPIPE and draining)
- v4l2: vp8 and mpeg4 decoding and encoding.
- v4l2: hevc and vp9 support.
- v4l2: generate EOF on dequeue errors.
- v4l2: h264_mp4toannexb filtering.
- v4l2: fixed make install and fate issues.
- v4l2: codecs enabled/disabled depending on pixfmt defined
- v4l2: pass timebase/framerate to the context
- v4l2: runtime decoder reconfiguration.
- v4l2: add more frame information
- v4l2: free hardware resources on last reference being released
- v4l2: encoding: disable b-frames for upstreaming (patch required)

- there is no need for kCVImageBufferColorPrimaries_ITU_R_2020 checks,
it's done at runtime
- VideoToolbox presence is now checked with check_apple_framework()
- link to CoreServices is only done when videotoolbox is enabled
$headers is a variable set in the context of other functions (we don't
use the "local" keyword in our scripts, so those variables are global).
Currently, when checking for AVFoundation/AVFoundation.h, the actual
enabled header is math.h.
Similarly, when testing for QuartzCore/CoreImage.h, the actual enabled
header is CoreGraphics/CoreGraphics.h.
This is completely broken and may be the reason why these checks are
made in random places.
