bmesh python api
* BMLoop attributes link_loop_next/prev
* BMVert.copy_from_face_interp

bmesh code cleanup
* minor edits to header
* make BM_vert_dissolve() easier to read.

fix [#30352] Dissolving a vert in an edgeloop (no faces) just deletes the verts killing connections

collapse the vertex into an edge when it has 2 edges connected to it.

bmesh api cleanup
* better type safety for BM_elem_flag_* and BM_elem_index_* functions.
* add BMElem type to be used where BMFace/Edge/Vert/Loop can be interchanged.
* fix bug in select manifold, found when making functions more strict.

minor style edits
- use GL_TRUE/FALSE for glLightModeli
- use set for python checks against multiple string values.

adjustment to r44436.

dont set the header text multiple times when many objects are selected, instead just print the difference thats applied.

when theres a single object selected, behavior us unchanged.

Merged changes in the trunk up to revision 44436.

bmesh code cleanup
* change BMO_elem_flag_* defines to inline functions.
* BMO_slot_map_insert() is too big for an inline function - un-inline it.
* remove redundant casts.

Patch [#30341] by Davis Sorenson (dsavi). Thanks!

* Now the 3D view header displays value changes, when changing a value in the Object Special value (w-key).

bmesh api:
* added BM_elem_flag_set, BMO_elem_flag_set. to avoid 'if(...) enable(); else disable();' all over the place.
* added bmesh_operator_api_inline.c, the header file was getting messy.

fix for own error edge tagging sharp.

Changes in double side lighting usage

Disabled double-side lighting by default and changed areas which are using
double sided lighting to switch it off just after doing stuff which requires
double side.

This makes code a bit more simple to follow (no all that disabling double side
lighting all over the code and so).

This change also fixes crash of blender caused by intel gme965 driver which
leads to stack corruption in some place when double side lighting isn't
disabled (probably driver still kind of using double side in some areas or so).

Hopefully it'll also fix #30293: Converting Text to Mesh

Thanks to Campbell to assist writing this patch!

style cleanup, use { on newline after function definition.
spelling 'impliment' -> 'implement'

code cleanup: white space, spelling & ';;' end of lines.

bmesh py api - add funcs
* BMFace.copy_from_face_interp(face)
* BMLoop.copy_from_face_interp(face, vert=True, multires=True)

These are important for rebuilding geometry from existing faces without loosing UV's, vcols etc.

[#30197] Snapping: Align rotation button

Reported by Pep Ribal

Volume snapping was showing invalid options.

fix for own regression in r44361 (broke BM_vert_in_face)

also fix py api: bmesh.utils.face_split(face, v1, v2)

OSX: scons: fix own mistake, truncate output of xcode-build -version to major.minor version in config to change the var not only the print

OSX: scons: corrected output string of xcode-build -version, so only major/minor version is used

bugfix
* ntreeCompositExecTree accessed 'ntree' before NULL check.
* BM_face_triangulate accessed 'f' before NULL check.

also quiet warning in BKE_text_to_curve() and add a check for BMesh bridge loops so it knows quicker if it can copy loop data or not.
