Summary:
Removed all ABS() macros.
Revision:
xvidcore--devapi4--1.0--patch-14
All ABS macros have been replace with their stdlib.h/math.h
equivalent. This gives a 33% overall speedup for the plain C encoder,
while the ia32 one seems to suffer a small speed loss. However this
speed loss is very small and it seems it depends on the CPU type as
the abs/fabs usage is impacting badly on sad functions but impacting
well on interpolate functions ... weird inst'it ?

Big patch, use it with care (tests done with GNU/Linux) :
- Trivial warnings in encoder.c line 282 ret1 = ret 2 = 0;
- Lot of "New line at end of file missing" warnings fixed (gcc3)
- All 2d arrays have been turned into 1d arrays
To force alignment of matrices on stack, use DECLARE_ALIGNED_MATRIX
(read portab.h)
Win32 users should give feedback.
