The reversing bframe formula in 2pass 2 was not right. This was in fact
a test code i used when i was maintaining the code on its own branch.
I should not have commited it :\

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.

Simplified equations.
Scaling was needed because of the non linear formulas used in AltCC but
now we can directly use avg_length[s->type-1] instead of "first prescaling
bframes to pframes lengths then use pframe stats and at last prescaling back
frame length to bframe lengths"
See my new XXX: question about the overflow.

I read VFW and noticed that min_length was supposed to be:
min{hard coded length, min{observed lengths}}

- Some comment changes
- bquant_error and pquant_error have been replaced by an array
quant_error[3][32] indexed by frame type and quantizer value.
- Moved some initialization stuff

After reading VFW code, i found out that it was using the blocks stats
fields to retrieve the number of MBs in a frame. So all this
min_size[] was not meant to discover a min_size for each frame
according to its intra MBs but rather an hardcoded minimum for all
frames as advertised in earlier cvs revisions. It would be easier if
original code was commented :-(

Added frame type to the debug output. It makes clear that
bframe quantizers are too high compared to their reference
frames' quantizer.

- function ordering changes
- mimimum frame lengths in internal_scale() are now computed for each
frame, i don't know why these values where computed with the first
frame values only.

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).

* 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
