Fix for unfreed effector weights in hair dynamics.

The internal cloth modifier effector weights get replaced temporarily
to make the cloth sim use the particle weight settings instead. But
the particle sim was not putting back the original weights, which can be
non-NULL in case the cloth sim allocated these already. Messy design ...

Selection: avoid uninitialized memory read with occlusion queries

Adjust GLSL drawing of window coordinates from camera view (use camera
bounds instead of window bounds). Fixes remaining part of T43346

Fix for unfreed memory due to unnecessary early exit in the free
function.

Fix for hair child roughness.

The fixed-function roughness was not getting used once the curve
roughness has been enabled at least once.

Fix for unfreed memory of internal hair cloth modifier pointcache.

minor tweaks

- shorten text for message (no need to be toooo polite :) )
- use_center_bounds (matches Poly.calc_center_bounds)

Fix rendering of clnors with flat faces.

Basically, you can define any custom normal on flat faces too, which makes
them (more or less) smooth... So simply consider all faces as smooth when
we have some lnors now.

Various cleanup...

Add a 'lnor spaceset clear' func too (avoids freeing the memarena).

Not crucial currently, but could be later, and for sake of consistency...

Cleanup: rename 'spaces' -> 'spaceset'

Not a good idea to make names like MLoopNorSpace/MLoopNorSpaces...
