sws_getCachedContext() and sws_getContext() expect sws_alloc_context()
to return NULL when out of memory, as follows.

    if (!(context = sws_alloc_context()))
        return NULL;

This patch fixes sws_alloc_context() to return NULL in that case.

The version number is useful to check the libavutil version against which
the library was compiled at run-time, which in turn may be useful to deal
with binary compatibility issues.

SWS_CPU_CAPS are deprecated and slated to removed with libswscale major
version 3. No need to provide a SWS_CPU_CAPS_MMX2 as backward
compatibility define under the same explicit condition.

Otherwise during scaling it will try to interpret input in the wrong way and
that leads to the test results disagreeing on different platforms and with
different optimizations.

This is more consistent with the way we handle C #includes and
it simplifies the build system.

This is necessary to allow refactoring some x86util macros with cpuflags.
