Took out OpenMP refactor out by mistake

Revert changes that disable features on MinGW.

To compile on MinGW it is important to have the latest MinGW (gcc 4.6.2)

I have updated the instructions on the wiki to reflect this: http://wiki.blender.org/index.php/Dev:2.5/Doc/Building_Blender/Windows/Environment

fix [#30907] Inset tool with Select Outer disabled does not allow translation of new faces

inset with select-inner faces gave invalid selection.

also correct spelling in some comments.

doxygen docs explaining whats going on with shape-key conversion.

cmake/mingw now builds with default configuration (needed to disable tiff/exr/cycles)

code cleanup: remove duplicate define on windows.

code cleanup: quiet some mingw warnings.

code cleanup: avoid confusion with utfconv lib - was configuring this windows only lib on non windows platforms (scons only).

code cleanup: utfconv library had some quite confusing formatting, also cleared som warnings.

code cleanup: remove unused var for windows and style edit (remove spaces between 'var[num]')

fix [#30771] Shapekeys: Basis shapekey is not kept in sync with "RealMesh"

behave the same as in 2.4x.

- merge BMesh / Pre-BMesh code shape key conversion code, old code was called as a fallback but merge instead.
- fix possible crash - new bmesh code was clamping the vertex index for the oldverts array by the new total number of verts.

bmesh shape key conversion on exiting editmode.

there were 2 blocks of code (both calculating the offset array), now move the fallback method into the main key conversions block.

bmesh exit editmode shape key conversion - split out 'keyblock --> customdata layer index' into its own function, makes code easier to follow.

bmesh shape key conversion when exiting editmode.
- avoid running old conversion code if its not needed.
- de-duplicate functionality which gets offsets from edits made in editmode.

libmv: bundle new upstream version from own branch which should support
compilation of glog on hurd platform.

Game engine: pass string length to BLI_str_cursor_step_prev_utf8 rather than NULL

That's what this function expect (but somehow does not use) and it gave compilation
error when using gcc-4.6.3 from debian linux.

write mesh selection history to the blend file. without this active edge/vert are lost on UNDO.

code cleanup: mselect conversion when creating a bmesh from a bmesh was overly verbose.

py rna/api: fix for error running RNA_property_collection_type_get on non collection property types.

Fix cycles opencl compile issue, fminf/fmaxf() was defined both as macro and function.
