> > + int intra_dc_threshold; /* fake variable */
This patch fixes a warning spotted by gcc 4.0.1, because &intra_dc_threshold
is passed to some function which expects a int*, not a uint32_t* (on 64bit this
is important, even if this is fake data, the callee could corrupt the stack
writing 64bit to a 32bit allocated destination)

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

encoder.c: simplify_time() optimized by Euclid.
bitstream.c: write_video_packet_header() was buggy and
kind of obfuscated, as noticed by Sigdrak at free.fr.
from Edouard:
gcc4 warning removal.
- No executable shared objects installed
(Do not install the lib as executable. It's no use as the SO has no
main symbol anyway, and the static lib is not runnable anyway.)
- Statically link xvid_bench with libxvidcore.a
- New autoconf garbage removal
- Quotes in configure.in

encoder.c: better error handling upon MEM_ERROR
bitstream.c: faster log2bin (xvid_bench.c updated)
bitstream.c: added unused functions:
BitstreamWriteEndOfSequence()
BitstreamWriteGroupOfVopHeader()
write_video_packet_header()
Original input: sigdrak at free.fr and Angela Belda. Thanks.

xvidcore
========
* added XVID_GLOBAL_DIVX5_USERDATA global flag
* removed the bvop delay warning text ("warning: nothing to output), as this often confuses joe user.
* minor changed to closed gop image_printf statement: s/"DX50 BVOP->PVOP"/"CLOSED GOP BVOP->PVOP"
* additional comments for low_delay_default mode within decoder_decode()
* divx userdata string: s/DivX999b000/DivX503b1393. this has been suggested by dxn for improved hardware compatibility [nb: i dont have a hardware player to confirm this]
* vbv_peakrate constraint is ignored if <= 0
vfw frontend
============
* dxn profiles now confirm to "DivX Certified Profile Compatibility v1.1", February 2005. this document was provided by DivXNetworks, USA. when a dxn profile is selected, strict conformance is enabled:
- force 1:1 picture aspect ratio
- disable bframes if interlacing is enabled
- force maximum of 1 consecutive bvops for the portable and ht profiles, 2 bvops for the hd profile
- always write divx 5 userdata string to bitstream
- force packed bitstream option
- updated dxn vbv parameters
* added PROFILE_4MV flag. 4mv is now disabled for the dxn handheld profile.
* moved PROFILE_AS/PROFILE_ARTS/PROFILE_S to config.c
* profile[].max_bitrate now measured in bit/sec (not kbps)
* profile->level box: widgets are now greyed-out if they are not used.
* increase vertical size of profile drop down list.
* about box button: s/Dismiss/OK

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.
