* Style cleanup / Cycles.

correct include guards and add checks in check_style_c.py for them.

Ensure positions can be read for sources that have stride
defined as 2 (2D coordinates).

Fix own stupid error in previous commit... :/

Prevent assert failure in knife.
It seems sometimes a knife edge with the same
vertex on both ends was created sometimes.

Fix potential crash in knife.
A crash was reported but without info to reproduce.
This is a likely crash introduced by previous fix
to allow linehits to snap to vertices.
The function to find connected linehits can't
assume all linehits have edges any more.

Potential fix for install_deps.sh OSL build issues reported by users: run ldconfig immediately after lib compile (looks like OSL compile process needs boost libs...).

Fix #36755, EXR Layers are not fully updated on scene load or image refresh.
After discussion with Brecht decided that automatically updating the sockets of the node based on externally modified data (removed EXR file passes) is not desirable behavior. But at least making sure
the correct passes are assigned to the output sockets of the Image node is possible. Now the passes are matched by name instead of using the faulty index stored in the socket data, which is more
reliable. Still may break if changing pass names externally, but an image reload is highly recommended anyway and will fix that.

Fix for OutputFile node, this would crash with unconnected sockets in MultiEXR mode, because it matches sockets and EXR layers by index and was skipping unconnected sockets. Simply create EXR layer info
for all sockets now and then ignore unconnected layers when finally writing to file in deinitExecution.

speedup for ngon tessellation, check if the angle is an improvement before doing the full intersection check.
with 500 verts gives approx 2x speedup.

minor edits to poly_find_ear() bmesh function, no functional changes.

fix [#36625] Particle Instances ignores Group offsets
in fact this failed for all nested dupli types except for dupli-groups, (which ignore the 'par_space_mat' object_duplilist_recursive()).

replace macro PYC_INTERPRETER_ACTIVE for PyC_IsInterpreterActive() function call,
(indirectly referenced Python define of ~30 lines, most were optimized out but still caused some code bloat).

style cleanup

fix [#36771] Prevent 'Apply Transform' for Objects with a linked mesh

bugfix: [#36641] Maya keymap: Border select doesn't add to selection

I also replaced all EVT_TWEAK_L by EVT_TWEAK_S
- and replaced B by the gesture mouse for the clip keymaps

Fix warnings message on load about packed images:
ERROR: Image not available. Keeping packed image

This was due to recent bugfix for #36639, the image should only be reloaded if
the path actually changed and it's not a packed file.

Fix memory leak that still existed when opening .blend file mesh data in older
Blender versions, previous fix only solved it for newer versions.

Fix a memory leak in packed files.

Fix #36754: animation not evaluated on object two levels down in dupligroups.
Depsgraph would only consider one level, now it works recursive.

UVProject modifier was still requiring old tesselated UV data instead of new poly/loop ones.
