3737dd1cd3 PPC: implement MULH() in assembler 
Left to its own devices, gcc calculates the full 64-bit product only to
discard the low 32 bits.  This forces it to do the right thing.

20% faster MP3 decoding on G4.

h264_idct_add16intra, h264_idct_add8 need to be implemented.

Add C version of ff_h264_idct8_dc_add in AltiVec so that ff_h264_idct8_add_altivec
can be used.

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.
