OSX/cmake: use again 10.5 as general deployment target ( pls verify 10.5 compatibility works with automatic weaklinking), use now then sdk which for sure exists, remove obsolete slash

Fix #30512: external render saved render result after reporting error.

Make knifetool more robust against crashes. Fix some hole problems.

Sometimes split would fail to make a face - make sure it doesn't
crash if that happens.
Chain finding code for holes would sometimes go back to same
vertex on the face, which causes problems, so fixe that.
Also, disallowed a cut that starts at a vertex or edge and
cycles back to that same point in a face - this would make
a face with a repeated vertex, which may not be handled by
the rest of the system properly.

Style cleanup in blenfont (spaces, C++ comments, etc.).

Removing SWAP macro define from BLI_heap.c, already present in BLI_utildefines.h, giving compile error.

Commit patch from Shane Ambler to make VideoTexture compile with a clang on FreeBSD.
Thanks!

Re-bundle libmv from own branch.

Should resolve compilation error on some platforms when using linux and
compilation error of libmv on FreeBSB.

It was a regression caused by not applied changes on config_linux.h
and some changes made to utilities.cc were also occasionally missed.

Fix msvc compilation errors. (__func__ undeclared)

code cleanup/bugfix uninitialized values
- edgebisect bmesh operator used uninialized beauty field.
- BLI_join_dirfile could read from before the string bounds when passed an empty dir string.
- pransform could use an uninitialized projected coordinate (unlikely but possible)
- RNA_property_path_from_ID_check would compare against an uninitialized pointer when the path wasn't found.

also have bmesh walker use BM_edge_other_vert() utility function.

style cleanup: line length - some over 300 long.

SVN maintenance.

fix [#30472] 3d view objects not rendered, cycles.

holdout layer wasnt initializes in some cases.

text delimiter - convert to unicode before comparing characters.

style cleanup

bmesh: edge loop select
add support for loop selecting boundry edges only - handy for loop selecting the side of an ngon.

Fix edge loop selection. Now boundary selection checks only for filled edges to determine when to stop and stops at vertices shared by only 2 edges.

Port changes from libmv/CMakeLists.txt to build rules files generator script

remove Object member from BMesh struct - was only used for undo and BMEditMesh already stores an object pointer.

also fix for own mistake with mesh conversion refactor, shape key index was off by 1 when switching editmode.

Bundle new upstream version of libmv from own branch

This version of libmv includes new gflags and glog libraries which makes
it possible to compile libmv with clang compiler.

Also remove code from CMakeLists which was disabling libmv if using clang.

Tested on linux with gcc-4.6 and clang-3.0, windows cmake+msvc and scons+mingw.
Could be some issues with other platforms/build system which shall be simple to resolve.

style cleanup, also remove unused externs.
