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- bquant_error and pquant_error have been replaced by an array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
