added mmx/sse2 code for GMC (3-pts only).
new file: image/x86_asm/gmc_mmx.asm
At this point, new GMC code isn't enabled (gmc.c:586).
So: this commit should give binary-exact same input/output
than before.
dsp/dsw not updated.

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

+ Added IEEE-1180 and Walken-compliant SSE2 Idct.
Disabled by default (line 515 of xvid.c) until proven fully
safe. Should give binary-equal results than the mmx and xmm

* Thread safe MPEG4 quantization functions.
Cleaned up version of patch provided by Michael
- fixed compiling problems on gcc
- added const qualifiers every where it was possible to help C compiler
optimization.
- added the mpeg_quant_matrices param to all ASM function prototype
in comments (even if it's not used, that shows we do it deliberatly)
- forces m[intra][0][0] = 8, otherwise XviD could write invalid streams.
* Added real CRC computing in xvid_bench.c

MMXed the calculation of SSE for 8x8 16bit blocks. This helps quite
a lot VHQ=4 mode.
My tests show with trellis:chroma_me:
- ~20% speed improvement for vhq=4.
- at least 5% when using vhq=1.
Of course this speedup vanishes if more CPU intensive features are
used. CruNcher who used gmc/qpel, noticed "only" a ~5% speed
improvement.
NB: i'm of course talking about overall speed improvement. Such a
small patch for such a big improvement :-)

* Added Dmitry SSE2 iDCT code back.
* Plugged Dmitry iDCT as default for SSE2
* Fixed a bug in xvid_bench that was making it would test some CPU
instruction set w/o host CPU support. xvidcore init was simply
discarding irrelevant cpu flags.

* Ported the ffmpeg fDCT functions (mmx and xmm).
* Modified the skal's versions a bit to allow rolling loops.
* Activated Skal's fDCTs (unrolled versions) for mmx _and_ xmm
(old code was ignoring xmm versions)
* Removed the SSE2 versions (they'll be back later)
* .data -> .rodata
* Applied announced asm CodingStyle to the dct dir
(I'll have to add a section with the said CodingStyle)

* dynamic bvop decision stats bug fixed
* added runtime debug level option. this only only activated when _DEBUG is defined.
level is specified globaly, via "xvid_glb_init_t.debug" and XVID_DEBUG_xxx defines.
references to previous DPRINTF_LEVEL_xxx's have been replaced throughout libxvidcore
* futher bitrate zone fixes for plugin_2pass2.c
* removed old ratecontrol.c from msvc project
* xvid_encraw.c specifc:
* added "-max_key_interval integer" option
* renamed -debug to -vop_debug
* added "-debug integer" option, which sets xvid_gbl_init_t.debug field
* s/length/len/ status line
* vfw specific:
* zone/bitrate typos fixed ("you eediot")
* renamed "debug" regkey to "vop_debug"
* added "debug" regeky and textbox which sets xvid_gbl_init_t.debug field

2003-04-10 GMT Edouard Gomez <ed.gomez@free.fr> patch-14
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 ?
