Partial fix to version_ge (greater or equal), was not working correctly with eaqual versions, now will do with exact same versions at least (yet have to fix case like comparing 1.0 and 1.0.0).

Also refactored a bit osl/llvm/etc. stuff for DEB (so that now all osl-deps are only installed when we do have a valid llvm and want to [try to!] build osl).

And added osl/llvm/etc. code for RPM (osl does not compile under fedora currently, though :/ ).

More cleanup/deduplication. Also explicitly using gawk (so system without it should print a much comprehensive error message!).

Note: RPM-related edits not yet tested.

Better handing of llvm version (now we can be sure to use the same for osl and blender - and the latest one available!).

And more cosmetic cleanups...

CMakeList: Better handling of llvm under linux (now you can try to force usage of a specific version of llvm before using default one).

Also cleared LIBDIR var from linux code, as we have no more those svn folders!

Windows / OSL:
* Scons cleanup, to avoid redeclaration of /EHsc. Linking still fails.

Fix own stupid mistake for threads count, and edits to user messages (mostly adding the ldconfig trick for dynamic boost libs).

Request from Riggers/Animators at BlenderPRO:

Armature modifiers added via Ctrl-P operation will no longer have "envelope"
deforms enabled. This helps cut down the number of unintended deformations
arising from rouge-sized envelopes or stray control bones.

bmesh: lazy initialize bmesh tool flag pool, has the advantage that modifiers that dont use bmesh operators can skip allocating it.

fix for skin modifier calling rotate_normalized_v3_v3v3fl with a non unit length axis.

bmesh: move internal API flags out of BMFlagLayer, into BMHeader which was being padded up anyway, added static assert to make sure it stays <=16 bytes.

bevel now only takes manifold edges (so it doesnt need to check for them)

bmesh function was still using bmesh operator flags, use edge tags instead.

commented bevel modifier code now calls bevel direct rather then the bevel operator.

finish moving bevel code out of the operator dir (it works again)

moving bevel to tools dir as-is to keep svn history (breaks build, will fix next).

move decimator into tools/ dir

move source/darwin into release/darwin since these files are for osx packaging.

OSL / Windows:
* Some fixes for scons, kernel/osl compiles now.
* Still disabled per default, as relative path to oslc.exe does not work and linking fails.

typo in own recent commit.

style cleanup: if's on the same line.
