Fix for garbage data in vertex weight array crashing software skinning.
Proper integration of picking for rigged attachhments.
Optimization in LLDrawable::updateDistance (don't call updateRelativeXform, just use spatial group position).

Use tcmalloc for windows (gives auto-magical 16-byte alignment whenever needed, much faster than Visual C++ malloc).

backing out patch from SNOW-606 as it breaks the build on our linux
build machines. Can be re-applied when our build machines get an updated
version of libuuid.

Updating cmake to ensure that linux uses the non-stub version of convex decomp.

Another typo - was disabling the UI, whether the debug option was true or false
simple copy/paste error.

Fixing a typo in my previous patch - want to use setRenderTypeMask instead of
andRenderTypeMask.

Deminimis change, no review

minor cleanup and fixing the linux build.

Fix for crash when loading models (Don't hit UI from the main thread).  Added asserts to LLFastTimer to verify main thread use only.

tweaked some numbers that were incorrect when I originally wrote the algorithm

First pass - uses the new algorithm to hopefully be more accurate of render load
on low-end machines. Also accounts for mesh complexity, including if a mesh is
weighted or non-weighted.

Probably a regression from the prevalidator rework - was enforcing non-negative int when precision=0 (i.e. non-float), should have been enforcing only full int range.

Fix double definition of create_jump_keys="true" introduced in the fix for VWR-20724 to pass coding policy check.

gcc doesn't like passing NULL where you mean FALSE. This unsticks the linux build.

de-minimis change, no review.

upon further review, falcon determined this fix was unnecessary.
