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

========
* 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

* 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

Valgrind reported lot of unitialized reads. These unitialized reads
helped sysKin finding three bugs:
- ZeroMacroblock did not reset the cbp field. So for some skipped
blocks, a test was done on the cbp value...
- MEanalysis was using wrong mvs from the current bvop (unitialized
or just wrong in current context). That's because in devapi3,
bframes used to share the same mvs array wheras now, it's one array
a bvop.
- Collocated skipped MBs for a bvop didn't reset mvs[0] and b_mvs[0].

New two pass code. I may say it's just a fixed version, though it looks
more like a "take all the ideas and write it again" version. It performs
better with all natural sequences i have and a bit worse with anime.
Including it now, allow me improving the code during the beta releases.

Patch from syskin.
* This patch avoids calling setedges and interpolate for uneeded cases:
- setedges is only called once per frame.
- interpolate is called only when the previous rounding
was different from the one needed.
* Interpolation has been optimized a bit for qpel case, we do the
hv pass down to top to use the cache more efficiently (hope so).

Removed this annoying \n from DPRINTF output. DPRINTF behaves
now like usual printf.
Just for fun, i decided to exercice my regexp skills:
for i in `find . -name "*.c"` ; do
sed s/'\(DPRINTF(XVID_DEBUG.*\)"\([^"]\+[^\\][^n]\)"\(.*\)$'/'\1"\2\\n"\3'/g $i > $i.tmp;
mv $i.tmp $i
done
Nice isn't it ? It just adds a \n to every DPRINTF call that
was relying on old behavior (automatic trailing \n).

Summary:
Adds extended stats support even for bframes in xvidcore.
Revision:
xvidcore--devapi4--1.0--patch-4
This patch enables core extended stats support even for bframes. It
modifies the way the MBTransQuantBVOP function does its work. It used
to not dequant, idct the MB because bframes are never used as reference
frames. However if we want to compute stats, then we must perform these
inverse transformations.
modified files:
src/encoder.c src/utils/mbfunctions.h src/utils/mbtransquant.c
