Field interlaced decoding, contributed by Christoph Kuehnel
decoder.c
=========
- Some new defines for DIV
- <decoder_mb_decode> modified: had wrong address offsets for interlaced
- <decoder_mbinter_field> = new function for interlaced
- <get_motion_vector_interlaced> = new function for interlaced motion vector prediction
- <decoder_pframe> modified so that it differs between frame and field prediction
global.h
========
- For field motion prediction MACORBLOCK has new member that is the average of
field1 and field2 motion vector = <mvs_avg>
xvid.c
======
- For field predicted macroblocks we need new field oriented transfer functions.
For colour calculations they may only process 4 lines (one field from the colour
macroblock that is 8x8). So I introduced 4 new function pointers:
<transfer8x4_copy, interpolate8x4_ ...)
mbcoding.c
==========
- _DEBUG code; index is checked against 64
interpolate8x8.[c,h,asm]
===========================
- New 8x4 functions
mbpredicition.[c,h]
===============
- New function <get_pmv2_interlaced> for interlaced prediciton according to spec
mem_transfer.[c,h,asm]
==============
- New 8x4 function

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.
