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.

configure: improve the help text for external libraries
Only merged the explanation paragraphs. The removal of "enable/disable"
and "[no]" would create too much inconsistency and might cause
confusion.

This avoids enabling and building the x264rgb encoder when its actually not supported and
thus would not work
Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
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.
