Merge of trunk into blender 2.5:

svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r12987:17416

Issues:
* GHOST/X11 had conflicting changes. Some code was added in 2.5, which was
  later added in trunk also, but reverted partially, specifically revision
  16683. I have left out this reversion in the 2.5 branch since I think it is
  needed there.
  http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=16683
* Scons had various conflicting changes, I decided to go with trunk version
  for everything except priorities and some library renaming.
* In creator.c, there were various fixes and fixes for fixes related to the -w
  -W and -p options. In 2.5 -w and -W is not coded yet, and -p is done
  differently. Since this is changed so much, and I don't think those fixes
  would be needed in 2.5, I've left them out.
* Also in creator.c: there was code for a python bugfix where the screen was not
  initialized when running with -P. The code that initializes the screen there
  I had to disable, that can't work in 2.5 anymore but left it commented as a
  reminder.

Further I had to disable some new function calls. using src/ and python/, as
was done already in this branch, disabled function calls:
* bpath.c: error reporting
* BME_conversions.c: editmesh conversion functions.
* SHD_dynamic: disabled almost completely, there is no python/.
* KX_PythonInit.cpp and Ketsji/ build files: Mathutils is not there, disabled.
* text.c: clipboard copy call.
* object.c: OB_SUPPORT_MATERIAL.
* DerivedMesh.c and subsurf_ccg, stipple_quarttone.

Still to be done:
* Go over files and functions that were moved to a different location but could
  still use changes that were done in trunk.

+///The btTriangleMesh class is a convenience class derived from btTriangleIndexVertexArray, that provides storage for a concave triangle mesh. It can be used as data for the btBvhTriangleMeshShape.
+///It allows either 32bit or 16bit indices, and 4 (x-y-z-w) or 3 (x-y-z) component vertices.
+///If you want to share triangle/index data between graphics mesh and collision mesh (btBvhTriangleMeshShape), you can directly use btTriangleIndexVertexArray or derive your own class from btStridingMeshInterface.
+///Performance of btTriangleMesh and btTriangleIndexVertexArray used in a btBvhTriangleMeshShape is the same.
+///It has a brute-force option to weld together closeby vertices.
