Made some function from DerivedMesh.c be avaliable from other modules.
Some naming changes to make naming more uniform. No functional changes.

It's necessery for further crazyspace changes and improvenments.

Bug fix for problem 2 in [#25973] Bake End Frame Not Configurable
* External caches didn't load for smoke straight away. Smoke caches store all necessary info in every file, so no need to try to look for an info file.

patch [#25978] mathutils fixes for bpy_types.py and vertexpaint_dirt.py
from Filiciss Muhgue (filiciss)

patch [#26030] Debian spec fix (Patch for #26028)
from Shinsuke Irie (irie)

Removed the internal_select parameter from ntreeCopyTree. This was used just in one place when duplicating nodes, which is not an actual copying of the tree. The node duplicate operator now copies selected nodes itself.

update pacman spec for newer python and match naming convention to debian spec.
also pre-compile python modiles.

Made group label callback function static.

add torus script wasnt registering.

cls.is_registered() class method for python subclasses of internal types.
Synonymous with ('bl_rna' in cls.__dict__)

bpy.utils.register_module() generator could go into eternal loop.

UI functions added to existing UI classes (operators adding their own menus for eg),
would stop the entire menu from drawing if they raised an exception.

now print the exception and continue.

Also added a verbose argument for bpy.utils.(un)register_module() to help test whats being registered.

use weak references for the internal metaclass typemap,
this should help with blender leaking memory with python classes though the bug is still not fixed.

minor python register changes.
- KeyingSetInfo classes are now collected like Panels, Operators etc so bpy.utils.register_module() can be used.
- move bpy.types.register() to bpy.utils.register_class

BGE: frame start/end in action/fcurves/shapekey to support floats
after discussion over the mailing-list it seems that it really makes no sense to restrict that. Specially since we have the "Property" playback mode that usually will be a float.

Since there is no need for do_version or whatoever I don't see a problem. Any Thoughts? Maube to allow it only through the Python API?

patch [#25809] Auto-Registration as utility function.
This removes auto-registration, committed by Martin r30961.
Realize this is a contentious topic but Brecht and myself both would rather opt-in registration.

TODO:
- addons need updating.
- class list will be modified to use weakrefs (should have been done for existing system too).
- will move bpy.types.(un)register functions into bpy.utils.(un)register_class, currently including these functions in a type list is internally ugly, scripts which loop over types also need to check for these.

Different method for blur node aspect correction. Now the user can still set different sizes for x/y blurring in relative mode, but choose to use aspect correction on either of the axes.

More options for the blur node filter size. This can now be pixel based or relative to both axes or just either width or height.

Bugfix #26013

Good discovery this one.
It appeared that "pose mode" changes were not registered in our undo system.
That way the first operator you try to redo after exit posemode fails.

Bugfix #26001

Adding a byte rect to float ImBuf was always freeing the mipmap levels.
Removed this convention since it crashes renders + image texture draw.

Proper ownership handling of ImBuf is high on the wish list :)

fix for crash with GLSL material when image couldn't be loaded.
also quiet pep8 warnings.
