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.

* Added support for defining properties for operator buttons, with
uiButGetOperatorPtrRNA. Needed to cleanup a hack that was there
for operator properties in RNA, now a separate OperatorProperties
type is used for storing operator properties, instead of being part
of the Operator type itself.
* Allow selecting menu items with mouse release instead of press again.
* Fix some cases with hanging tooltips in the UI.
* Only open tooltip when the mouse is still over the button.
* Remove an unnecessary redraw call, though the two mentioned
in the previous commit seem to be working OK (it's for action
buttons when you move the mouse away from the button, holding
the mouse button down).
* Fix missing alt key in key event strings.
which context to run the operator: WM_OP_DEFAULT, WM_OP_REGION_WIN,
WM_OP_AREA or WM_OP_SCREEN. This also replaces WM_operator_call_rwin
since it is more general.
This is useful for buttons and popup menus to run operators, and also
used by a new function to lookup the keymap item for that operator in
the right context.
which will then be set when the operator is called, example:
kmi= WM_keymap_add_item(keymap, "ED_SCR_OT_region_split", SKEY, KM_PRESS, 0, 0);
RNA_enum_set(kmi->ptr, "dir", 'h');
kmi= WM_keymap_add_item(keymap, "ED_SCR_OT_region_split", SKEY, KM_PRESS, KM_SHIFT, 0);
RNA_enum_set(kmi->ptr, "dir", 'v');
There is a hack I had to do here, since properties are defined
as member of wmOperator, will try to fix later, committing now
so it can be used already.
funtion WM_keymap_add_item() now returns keymap-item, so you can use it
to set default properties for operators with WM_keymap_property_set().
Brecht will fill in this function, requires rna magic!
Example: an operator ED_OB_OT_add_primitive can be configured with
keymap like this:
WM_keymap_property_set(keymapitem, "Primitivetype", "Sphere");
Similar conventions we can use later for button/menu calls.
This will make creating operators easier, allowing a developer to group
tools functionality nicely.
Part one of wrapping up area/region management.

This commit:
- brings keymap storage to WM, based on names/types. This structure
allows rna-ifying it too, so you can browse keymaps etc.
- creating areas and regions works slightly different now, wich
regiontypes stored in areatype.
Todo:
- better callbacks and structure for defining which handlers need to
be added.
- using region types to validate regions
- proper implementation of local region data
- code method for customizing keymaps. Current idea is that you have
to indicate an entire keymap to be custom, to prevent too complicated
merging problems of default and custom maps (like order, multiple keys
for same operator, disabling options, etc).
- Added standard "tweak" gesture operator, which can be set per region, to
generate EVT_TWEAK events. You can configure tweaks for any mouse button
and have handlers for such events check for modifiers etc.
It even stores tweak direction (8 directions). Might be fun to experiment
with tweak gestures N, S, etc. :)
In general it can be used to replace the current tweak code in 2.48
(std_rmouse_transform).
Test added: on screen level it now adds LMB tweaks, if tweak-South it splits
the area. Will be removed of course.
- Added to Border operator a property to store event used to end border with.
- Moved the "AZone" triangle drawing to the right context (area). It was on
screen level, not respecting area-redraws. Also cleaned up drawing for it,
and moved the "swap buffers indicator" square to look nicer. Those squares
are only for test!
- event-match function had bad code for checking for event-value. Made a
"KM_ANY" define so keymaps can be defined ignoring event values.
- Gesture todo: lasso, "real gesture" (like blender now has)
- on mouse-over edge, you can drag area borders around.
- note it's a handerized system now, so it updates UI while you
move mouse.
Feedback needed:
- read bottom part of the screen_edit.c file. It's the proposed
method for adding tools and handlers. I think it's close, but
might need some tweaks.
