This is a bugfix for ARMv4 assembly implementation of 'j_rev_dct'
function.
The problem was in the incorrect partially empty row detection. Even
if the first two coefficients in the row were nonzero, it handled this
just like the case with only the first nonzero coefficient.
Now this function produces exactly the same output as the stripped
down reference C version of 'j_rev_dct' (with the nested checks like
'if (d6) { if (d2) { ...' always evaluated as true, avoiding shortcut
branches).

Add missing one for FF_MM_ALTIVEC to avcodec.h.
Rename all the occurences of MM_* to the corresponding FF_MM_*.

There are multiple source files that are #include'd rather than
compiled, as they are used as template for generation of similar code,
like asm-optimised code. Some of these files are right now named with
a .h extension, although they are not header in any reasonable sense.
Rename them so that instead of being named with .h extension they are
named with _template.c as final part.

Neither the asm() nor the __asm__() keyword is 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 syntax.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

on armv4 that doesn't support this instruction. Futhermore pld is a nop on some
armv5 processor like arm926. Detect if pld is supported and have the
preprocessor remove it when it's not supported.
Fixes issue 393.
