Use bitfields in FormatEntry array to avoid wasting an int for each flag.

The used flag was mistakenly overlapping with chroma drop

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.

Anonymous structs cannot be forward declared and have no benefit.

Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.

On architectures such as x86 (both 32 bit and 64bit), the stack element
size is fixed, which maintains alignment.  Here, this change does not
break anything. However, we also support also other architectures where
this property is not maintained and therefore, applications will crash
horribly.

This change effectively forces all applications to be recompiled against
libswscale.

Reintroduce the internal symbol which was removed in:

    swscale: remove sws_format_name()

    Use av_get_pix_fmt_name() instead.

The symbol is used by some external libs (hi libx264!), this gives
time to them to use the recently added av_get_pix_fmt_name() rather
than an internal symbol.

They've accumulated enough new APIs and corresponding deprecated cruft.

This breaks API and ABI.

The replacement isn't ready yet.
