Context API
This adds the context API as described here. The main practical change
now is that C is not longer directly accessible but has to be accessed
through accessor functions. This basically adds the implementation of
the API and adaption of existing code with some minor changes. The next
task of course is to actually use this design to cleanup of bad level
calls and global access, in blenkernel, blenloader.

Error, Warning and Debug Info Reporting
This adds the error reporting API as described here. It should help
clean up error() calls in non-ui code, but eventually can become used
for gathering messages for a console window, and throwing exceptions
in python scripts when an error happens executing something.

- depricated area "headbutofs" and "headbutlen", which is now fully
replaced with view2d handling.
- needed to add header default V2D_ALIGN_NO_NEG_Y, V2D_LOCKOFS_Y seems
to not do anything atm :)
- new: running blender in debug (blender -d) will print the current
handler and operator in use (not mousemove)
