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.

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_".

ab35de18cb Don't include config.h from assembly, because the mplayer developers 
decided it was a great idea to put some (bogus, of course) C function
prototypes there and it doesn't seem worth bothering working around
that since all we wanted is HAVE_GPROF.

8b313a4787 Move Alpha optimized IDCT to own file. Based on a patch by Måns 
Rullgård <mru@users.sourceforge.net>.

I've left out the idctCol2 part, because W4 has recently been decreed
to be 16383, and also I doubt it will give a noticeable speedup.
