Fix #30716: Clamp To Constraint Locks up Blender after a while.

Issue was caused by object moved really far away (not just actually issue,
it's just about long mouse gesture and X-axis orientation which projects
position to quite large X-axis value) and for this location start offset
from curve length was calculating iteratively which takes plenty of time for
short curves.

Replace iterative search of offset with formula which seems to be working
in the same way and should be a bit more accurate.

Fix #30719: Align View to Selected has unexpected results on further view change

added Mesh.calc_tessface(), needed to update mesh tessface after bmesh edits.

also add py api BMDeformVert.clear()

fix [#30715] bmesh: select linked not ignoring hidden verts/edges/faces

add optional flag to ignore hidden elements.
also remove loop mask flag - since it wasnt used and vert/edge/face is enough.

More array modifier fixes.

* Skip calculation of merge indices if merging isn't enabled
* Clean up usage of BMesh operators to fix small memory leak
* Fix harmless BLI_assert in CustomData_bmesh_merge
* Another null-initialization fix in CustomData_bmesh_merge

Fix uninitialized variable in CustomData_bmesh_merge.

Caused a crash in array modifier with caps.

converting a mesh to an undo mesh now skips using bmesh operator.

BGE: This fixes a problem where lamps in inactive layers were rendering shadows buffers that never got used, which was a huge performance sink.

skip using bmesh operators for converting to/from undo meshes (gives some speedup)

Windows Blenderplayer: The console now closes when the Blenderplayer launches (like it does with Blender). To get it back, use the -c flag, which is finally working as described: "-c: keep console window open"

fix [#30402] modules dir missing from sys.path

fix [#30705] Playing animation in reverse prevents further forward playback

fix invalid *= on an un-initialized value when adding primitives.

Partial fix for array modifier vertex merge (bug 30195).

Two fixes:

* The find-doubles operator was overriding the "dirty" element
indices, so vertices were not being mapped correctly.

* In some cases a vertex can be set to merge with a vertex that is
also set to be merged, so added a loop to find the first unmerged
vert in this case.

Not yet working is the "First Last" merge option.

Also made some cleanups and added comments in the array/remove doubles
code.

This does two things for cleanup builds made with SCons:
1) Removes unwanted folders from Python/lib instead of just emptying them out.
2) Removes the test folder from Python/lib. This folder contains unit tests for Python (not the unittest module itself), and is about 10~12MB.

Fix #30702: game engine softbody weld threshold was exposed in UI, but actually
disabled in code because it doesn't work well, so hide the property from the UI.

Fix #30551: cycles passes combining did not always give identical result combined
with antialiasing/defocus, now divide out color at the very end instead of for each
sample.

style cleanup

Small cleanup for r45238, remove empty/unused function.

Cycles: shadow pass support. Note that this only takes into account lamps,
emitting objects or world lighting do not contribute to the shadow pass.

Consider this more as a pass useful for some compositing tricks, unlike
other lighting passes this pass can't be used to exactly reconstruct the
combined pass.
