It seems that binutils >= 2.18 just treat eax as rax but older versions fail.

Convert typeof keyword into __typeof__; this is a gcc extension and the former is not accepted in C99 without GNU extensions enabled (e.g. via -fasm).  This fixes compilation on PPC.

Neither the asm() nor the __asm__() keyword is not part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).

Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 synta.

These are only used in swscale_template.c (and thus don't need to be
made extern), and can be declared as ASM constants.

These two tables are not used outside swscale.c even though they are
declared also in yuv2rgb.c.

These functions are never called by themselves, the alias
interleaveBytes is used instead.

Instead of having a firstTime variable defaulting to 1, have a
warnedAlready defaulting to 0. While this should make no difference in
code speed at runtime, it allows to aggregate the four bytes of that
variable with clip_table in .bss section, rather than issuing a .data
section just for that.

As it is, libswscale require no .data section but .data.rel.ro (that
can be mitigated by prelinking), so the change might actually save one
page of memory at runtime (per process).
