improve SunCC flags accordingly.

This reverts commit cb8646af24.
This change has brough more issues than benefits, between compilation
time failures depending on flags used and code miscompilation causing
runtime crashes.
See the "[PATCH 2/2] configure: Enable GCC vectorization on ≥4.9"
thread in the ffmpeg-devel mailing list for the relevant discussion.
Visual Studio 2015 Update 3 introduced a new SSA optimizer, however
it unfortunately causes miscompilations. Until it is fixed, the new
optimizations are disabled and should be re-checked on subsequent
compiler releases.
Fixes recent FATE failure of fate-lavf-pam on VS2015.
This patch also makes BlackMagic drivers v10.6.1 a hard requirement.

Fixes#4124: Invalid argument '-std=c99' not allowed with 'C++/ObjC++'
C++ files fail to compile. This adds '-std=c++11' to CXX_FLAGS to fix.

This avoids enabling and building the x264rgb encoder when its actually not supported and

With compilers that do not support proper dead code elimination, like
Sun C 5.12, linking fails due to missing references to unavailable,
but also unused, symbols.

As the nvEncodeApi.h header is now MIT licensed, this can be dropped.
The loaded CUDA and NVENC libraries are part of the nvidia driver, and
thus count as system libraries.

The code needs only a few definitions from cuda.h, so define them
directly when CUDA is not enabled. CUDA is still required for accepting
HW frames as input.
Based on the code by Timo Rothenpieler <timo@rothenpieler.org>.
Group them in a subsection of the external library section. That should
make them easier to find and understand how they fit in the scheme of
things.
Also, rewrite the description text in a similar way as in the previous
commit.
Add a more accurate description of what the switches actually do (i.e.
allow using the given library, not enabling the corresponding
codecs etc.).
Replace the library descriptions, in many cases boilerplate text without
useful information, with a short summary of what the library does.
This uses a new MMAL feature, which limits the number of extra frames
that can be buffered within the decoder. VIDEO_MAX_NUM_CALLBACKS can
be defined as positive or negative number. Positive numbers are
absolute, and can lead to deadlocks if the user underestimates the
number of required buffers. Negative numbers specify the number of extra
buffers, e.g. -1 means no extra buffer, (-1-N) means N extra buffers.
Set a gratuitous default of -11 (N=10). This is much lower than the
firmware default, which appears to be 96.
This is backwards compatible, but needs a symbol only present in newer
firmware headers. (It's an enum item, so it requires a check in
configure.)

Register mmaldec as mpeg2 decoder. Supporting mpeg2 in mmaldec is just a
matter of setting the correct MMAL_ENCODING on the input port. To ease the
addition of further supported mmal codecs a macro is introduced to generate
the decoder and decoder class structs.

(the same as on Windows). Creating other DLLs makes no sense as they can't
be used.

The raspberry pi uses the alternative API/ABI for OMX; this makes
such builds incompatible with all the normal OpenMAX implementations.
Since this can't easily be detected at configure time (one can
build for raspberry pi's OMX just fine using the generic, pristine
Khronos OpenMAX IL headers, no need for their own extensions),
require a separate configure switch for it instead.
The broadcom host library can't be unloaded once loaded and started;
the deinit function that it provides is a no-op, and after started,
it has got background threads running, so dlclosing it makes it
crash.

This is added in 10.11, so we add a #define when building against older SDKs.
The decoder actually supports 7.1-channel eac3, but since the parser only
reports 6 channels, we end up decoding the 5.1 downmix (same as the internal
decoder) for now.
Previously, with JACK installed, the configure script would enable the
JACK indev; this broke on OS X due to an incomplete pthreads
implementation. Add some simple macros to map libdispatch to pthreads
on OS X.

The relocation hack broke debugging on mingw-w64 when using gdb. This
makes the reloc hack dependent on --disable-debug so it's still enabled
for release builds.
This is simply an immediate fix for the issue of broken debugging, we
should probably still look at the possibility of reverting it outright
if it proves to be more trouble than it's worth. For now keeping it
enabled for release builds is a reasonable trade off.
