82d1605fe7 Remove duplicated MM_* macros for CPU capabilities from dsputil.h. 
Add missing one for FF_MM_ALTIVEC to avcodec.h.
Rename all the occurences of MM_* to the corresponding FF_MM_*.

be449fca79 Convert asm keyword into __asm__. 
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.

7f0d242b14 Fix compilation on Mac OS X 10.4: Defining _POSIX_C_SOURCE hides the u_char & 
similar typedefs that sysctl.h needs. Since sysctl() itself isn't POSIX
undefining _POSIX_C_SOURCE for check_altivec.c seems the best way to fix this.

987903826b Globally rename the header inclusion guard names. 
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_".

80a61f08d2 Remove AltiVec vector declaration compiler compatibility macros. 
The original problem was that FSF and Apple gcc used a different syntax
for vector declarations, i.e. {} vs. (). Nowadays Apple gcc versions support
the standard {} syntax and versions that support {} are available on all
relevant Mac OS X versions. Thus the greater compatibility is no longer
worth cluttering the code with macros.

d9a5dab2da Remove uses of SIGILL for CPU extension detection, that method is not acceptable 
in a library.
Should not change anything for PPC, the autodetection is currently pointless due
to other code being compiled with -maltivec as well (and detection for OSX and
AmigaOS remains in place).
SPARC binaries built with VIS support can now only run on systems with VIS.

22fa38f0c8 part 2/2 of fixing Altivec-accelerated H264 luma inloop filter 
In h264_deblock_q1, the result of the deblock needs to be kept to
be used in future deblocks, so return this value now.

Also change the sign of tc0 vector: It is really a signed value, so
treat it as such until after the >=0 check;
then, at that point, after being masked, it can be treated as unsigned.

f4a02f6e9b Use a faster way to compute 255-val: Instead of creating a vector of 
all 255s, and then doing the subtraction, nor of the vector with itself: saves
one instruction and a register.

fbb578e90d some samples aren't decoded correctly such as 
( http://www.pennfans.net/files/videos/Penn&Teller.on.The.View.mp4 )
with current Altivec implementation of loopfilter, while others are fine.
Let's disable it until we iron this bug out.
