without the underscores these clogged up the namespace for autocompleation which was annoying.

* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
setting. (not a bugfix exactly but would do display list context switching
while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.

Integration is still very rough around the edges and WIP, but it works, and can render smoke (using new Smoke format in Voxel Data texture) --> http://vimeo.com/6030983
More to come, but this makes things much easier to work on for me :)

Not working:
a) rendering (since volumterics branch is not merged yet)
b) moving collision objects of any kind
c) saving of collision objects (because that's what I am working on)
d) pointcache
e) A bunch of other things I already know of
So please do not report any bugs on this one yet :-)

Please check if volumetrics are yet working

not necessary to modify the BVH functions.

Replaced the previous KD-tree (for caching points) with a
BVH-tree (thanks to Andre 'jaguarandi' Pinto for help here!).
The bvh is quite a bit faster and doesn't suffer some of the
artifacts that were apparent with the kd-tree.
I've also added a choice of falloff types: Standard, Smooth, and
Sharp. Standard gives a harder edge, easier to see individual
particles, and when used with a larger radius, Smooth and Sharp
falloffs make a much cloudier appearance possible. See the image
below (note the settings and render times too)

- Particle now use the deflector objects collision modifier data to collide with deflectors and as a result can now use the velocity of the colliding object for more realistic collisions.
- Dynamic rotations are also quite a bit more realistic and are related to the friction setting of the deflector (to get any dynamic rotations there has to be some friction). This is largely due to the separate handling of rolling friction (approximated to be 1% of normal sliding friction).
- Collisions should be a bit faster on complex deflectors due to the tree structure used by the collision modifier.
- Collision should also generally be a bit more accurate.
To be noted: Only the average velocity of individual deflector faces is used, so collisions with rotating or deforming objects can't be handled accurately - this would require much more complex calculations. Subdividing the deflector object surface to smaller faces can help with this as the individual face velocities become more linear.

neighbour, non-recursive now, faster than kdtree.c implementation normaly, divided into 2 sources: generla structure in blenlib, mesh/derivedmesh depending interface stuff in blenkernel
|
|
BLI_kdopbvh (just like kdtree interface now), huge speedup for selfcollisions, also better normal collisions (merge from cloth branch)

system (better + general access to kdop, uses less memory, put it into BLI_* namespace and usage defined like existing BLI_kdtree_*). Deleted old kdop.c
