hair update

Render Branch: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r28485:28488

hair collision test is a little better. also fixed a mem leak and hopefully fixed a hang that can happen sometimes.

Render Branch: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r28464:28473

hair collisions are much improved. and rewrote goal code to not suck.

last merge broke

Render Branch: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r28457:28464

moved goal code to be an external force processed by the implicit system, not part of the internal solver itself (the code there doesn't work, is hacked, explodes, etc)

Render Branch: Fix for last fix...

Render Branch: Fix local light groups not working in some cases.

Render Branch: Image tile cache was not thread safe combined with threaded
compositing nodes causing crashes.

Render Branch: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r28425:28457, note: missing changes from properties_particle.py

=Hair Dampening and Collision=

Some durian features; added a new dampening mode to hair (and cloth, since
they shared the same dynamics code), that blends velocities with what the velocity
would be if the hair or cloth was a stiff rigid body. It's called "flexibility dampening"
for now. Note that the code doesn't go through the solver directly, but this *is* an implicit
solver, and integrating this sort of outside stuff is the whole point of implicit systems.

Plus it works better for solving durian issues as quickly as possible (jahka: pin stiffness for hair is totally unusable btw).

Also added collision for hair, extending the existing collision code. I have more reliable
code then this, but it'd b a bit of work to have it co-exist with the existing collision
code (the other code replaces all of the collision code, so I'd have to rework it to coexist instead).

Sprinkling some winstuff magic dust to make sure blender also links on Windows platforms.

Please remember to put in the BLI_winstuff.h in proper ifdef block whenever using something like snprintf() or seek(). Also good for places where maths defines are used. (the header defines the much-needed _USE_MATH_DEFINES on Windows , gives you nice M_PI and such.).

Fix for compile error where declarations happen *after* statements in a block. (joeedh, next time put those new statements after decs in a block ;) )

fixd hair smoothing crash

Render Branch: fix for crash with material light groups local option.

Render Branch: Fix for FSA update while rendering fix, should set
float rect to NULL.

Render Branch: fix for irradiance cache mutex unlock that got lost
in code changes.
