Fix loading external MDisps, BMesh merge bug.

* When converting mfaces to mpolys, load external MDisp data in, add
CustomDataExternal struct to loopdata if needed.

* Fix multires modifier's filepath RNA functions to use ldata rather
than fdata.

bmesh api changes:
- remove recently added BM_mesh_select_flush_strip(), functions purpose wasn't clear.
- add BM_mesh_elem_hflag_disable_test(), BM_mesh_elem_hflag_enable_test()
to match existing BM_mesh_elem_hflag_enable/disable_all(), these take a hflag to test before editing each element.
This replaces the need for BM_mesh_select_flush_strip().

fix for UV reveal (wasnt selecting all verts because check for unselected vert was incorrect after selecting the first face).

Code cleanup:
* Remove some non used *_button_register functions, panels are done in python.
* Remove do_node_region_buttons, was not used anymore.

Fix:
* Only show Grease Pencil panel in the Node editor, when there is a valid nodetree.

Fix part of #30917: solid + glsl + textured solid in texture paint mode did not
show textured solid as it should, was using glsl instead.

svn merge ^/trunk/blender -r45364:HEAD --accept postpone

Fix related to #30917: wrong colors in cycles textured draw mode in some cases,
missed call to glColorMaterial made glEnable(GL_COLOR_MATERIAL) behavior
undefined.

improve mesh error prints and quiet a print in mesh_ensure_tessellation_customdata() which happened too often.

Scons / Windows release build configs:
* Enable CUDA per default, only thing the builder has to do for release libs, is to specify BF_CYCLES_CUDA_NVCC.

Fix #30919: Selection of multiple objects after EDIT MODE with MAYA PRESETS Keymap

Issue was caused by operator presets.

Fix: subsurf UV was not working correct with n-gons, it still had hardcoded
4 vertices per face code in some places.

Minor code cleanup: Don't reference previous BMwEdgeringWalker after BMW_state_remove. Its memory is freed on that call.

Fix: loopcut didn't stop on hidden faces

code cleanup: remove unused KeyBlock.adrcode

Fix: cycles not using local 3d view camera when it is decoupled from the scene.

libmv: bundle new upstream version from own branch with rigid registration implementation

Currently not used in blender code but is needed for some current work.

bmesh shape key conversion.
- remove print for impossible error.
- add NULL check incase bmesh and mesh get out of sync (would crash if Basis key-block couldn't be found).

bmesh exit editmode: when a mesh shape-key customdata layer exists but the shape-key-block isnt found, creating a shape key was allocated and inline - it didnt set the name or uid, Now use add_keyblock() as every other function does.

change add_keyblock() not to sort keyblocks by time since this can be a problem when using the function in lower level parts of the code, instead add add_keyblock_ctime() which sets time and sorts on absolute shape keys.

add in a check for Mingw so 4.5 or older will error out on build.
