fix for error pointed out by Nicholas Bishop, BM_edge_face_pair & BM_edge_loop_pair returned TRUE for single face user edges.

code cleanup:
- remove duplicate includes
- blender builds with -Werror in C++ for fluids/smoke

readfile.c Style cleanups Part 2 - More whitespace + replaced most of the while
loops

== Compositor ==

This fixes occasional crashes on uninitialized memory, when we open a blend
file which has movie or image input nodes pointing to none existent
source files.

code cleanup: spelling

Fix #31511: GLSL preview is much darker than F12 results

A problem caused by Harmony branch code. A value was being set improperly for the GLSL shader.

code cleanup:
- style - multi-line ifs move braces onto new lines.
- iterators - convert some to macros, other split up and move brace.

use utf8 functions for new modifier names

Renamed the COLLADA Import/export labels to 'Collada (Default)' to make it better separatable from target specific exporters

Sequencer UI:
* Some consistency tweaks.

Fix bug #31529 Remesh remove Apply as Shape button

Change modifier_sameTopology() to not not treat Nonconstructive
modifiers as having same topology. This function is only used to test
whether Apply as Shape is allowed.

The exact nature of "nonconstructive" modifiers is not documented, but
current list is remesh, fluidsim, decimate, mask, build, and
boolean. All of these modify topology, and should not be making making
shape keys.

Various small fixes:
*i18n: panel title of current tool in 3D view & File windows are now translated, as well a redo (F3) menu.
*MESH_OT_faces_select_linked_flat & MESH_OT_edges_select_sharp: use ANGLE RNA prop for sharpness, and fix tip of the later op.

BMesh Py API Fix: hide attribute of BMesh elements was returning the select flag. Fixed for all elements including loops, although this is commented out anyway. Reported by Crouch in IRC.

Fix memory leak when trying to apply transformations to shared meshes

Sequencer UI:
* Code cleanup
* Fixed wrong label for Inverse Select in the Select menu
* Some layout tweaks for space saving and avoid abbreviations in the UI.
* "Image Offset" and "Image Crop" buttons were there twice, once in the Strip Input panel and once in the Effect Strip panel, show it in the Strip Input panel only now.
* Commented the third input fields ("input_3"), only used by the deprecated plugin system according to an RNA comment.

Fix sculpt layer brush, broken by texture changes in r46651.

Added 'LIBRARY_EDITABLE' flag to bpy.props.*

Rationale: custom props on linked objects are editable through ops and the console but the UI code calls RNA_property_editable() which returns false if (id->lib && !(prop->flag & PROP_LIB_EXCEPTION))

Setting the 'LIBRARY_EDITABLE' flag allows UI templates to change these props (but the changes aren't saved!) for things like indices into CollectionProperties which live on the linked object

Fix [#31535] Radian Unit System Button Ignored for Face Angles display.

Also avoid multiplying each vertex three times with obmat...

Fix aspect ratio correction for translating motion tracking data

Still has got some issues when translating masks.

style cleanup: whitespace/indentation
