fixes/minor improvements to circle select in armature and pose mode.

- pose mode now checks if circle select intersects the bone if neither head/tail are reached (as with editmode)
- checking if the mouse intersects with the bone now checks that neither projection failed.
- use ED_view3d_project_int_object rather then the global version.

fix for circle select ignoring lock selection option for pose and edit modes, added macros PBONE_SELECTABLE, EBONE_SELECTABLE

replace ED_view3d_project_short_* with ED_view3d_project_int_*, when the result was converted to an int after.
also optimization for particle editmode key_test_depth() was projecting the screen coords, but all callers had already done this, so pass an arg.

knife tool: avoid sqrt's for length comparison, and define KNIFE_FLT_EPS rather than using (FLT_EPSILON * 80).

fix for bug in loop select, picking the active vert/edge/face was using global space checks on object space coordinates. this removes last use of ED_view3d_project_float_noclip().

replace most uses of ED_view3d_project_float_noclip() with ED_view3d_project_float_global/object

replace ED_view3d_project_float with ED_view3d_project_float_global

Improvements for knife tool execute function (code was a bit sloppy & could leak memory).

- vertex to screenspace projections were not checking for failure to project (vertex behind the view for eg).
- vertex screenspace 2d vectors were each malloc'd and added to own ghash, then fetched for each edge.
now just store a vertex aligned array and do index lookups.
- projections were done in global space, now do them in object space (avoids a matrix multiply).
- error cases were commented out and would fail silently, now report them to the operator.
- remove MAX_CUTS hard coded limit, dynamically allocate the mouse path.
- add missing free calls in error cases.

code cleanup: quiet warnings and use define for transform snap max distance.

add ED_view3d_project_float_global, ED_view3d_project_float_object, ED_view3d_project_float_ex function calls and cleanup cursor3d set function which had some odd logic.

* Fix Scons build when OCIO is disabled.
Still fails when it's enabled though (unresolved symbols).

Cycles: add "From Dupli" option for texture coordinate node. This gets the
Generated and UV coordinates from the duplicator of instance instead of the
object itself.

This was used in e.g. Big Buck Bunny for texturing instanced feathers with
a UV map on the bird. Many files changed, mainly to do some refactoring to
get rid of G.rendering global in duplilist code.

Mesh Deform Modifier: binding is now accelerated with a BVH tree, can make it
much faster for complex meshes. Patch by Joe Eager.

Quick fix for [#32764] Some new object types are added at the origin instead of the 3D cursor

Own fault (r50994). Those "add object" ops really need a cleanup to make them more consistent! Will try to see this tomorrow.

Fix #32763: Image flickering appears if Movie Clip Editor and compositor opened

The issue was caused by compositor was allocating float buffer for image and
then this buffer was filled with data converted from byte buffer.

If display happens at time between float was allocated and it was filled black
areas were appearing on the screen.

Made it so IMB_float_from_rect locks color management thread so display
transform wouldn't use uninitialized buffer anymore.

Fix #31806: cycles crash rendering a particular node setup with multiple mix/add
shader nodes.

UI: buttons that open menus now align to the menu rather than looking disconnected.
Also fixed some cases where the menu was offset 1 or 2 pixels wrong, though not
quite all of them, still off by 1 pixel sometimes.

Code cleanup: fix some clang checker warnings.

Fix for commit r51049: no need to create two contexts when one if enough.

Also please define and use constants in BLF_translation.h rather than directly typing contexts' names, it's safer (typo would break at compile time, instead of generating more contexts!).

Fix #32755: Stripes in Metastrip can not be moved on other channel with mouse (grab tool)

The issue was caused by SEQ_BEGIN macro modifying sequence's depth
which ruined transformation routines. Used own DFS instead which
doesn't modify sequences.

Also corrected some typos in api and comments.
