Checkpoint: sequence encoder state logic modified to support
2-pass and look-ahead coding.

- All state needed for pass2 is in Picture structure
- Improved parallelisation support
- Hooks for convenient implementation of pass-2 coding
- Function names now correctly distinguish 'Picture' and 'Frame'

Ooops CBR set to false when set. Doh!

The vectorcope now lookes like one, it has a description.

Put SDL_gfx related variables inside an ifdef to avoid 'unused' variable
warnings when building without SDL_gfx

User request: Add -C flag to force CBR

Keeping up with the code changes. The -s (spatial) filter defaults to
disabled now since the -m (3D median) filter does a similar job (as good or
better I'm told).

forgot to remove some comments...

need to include config.h (like all the other source modules do) so that
HAVE_STDINT_H and other defines are in scope.

Fixed a compiler warning where a file was included a 2nd time.

Fixed the problem with the heigth and width. Reported some time back in that tacker item:
https://sourceforge.net/tracker/?func=detail&atid=105776&aid=1296447&group_id=5776

Now the vectorscope output really works fast.
Vectorscope and histogram is now faster than realtime, and not flickering any more.
