Preview icon rendering for menus now runs in a separate thread, to avoid
blocking the user when opening a menu. Material and texture buttons now
display these icons in the list. Also fixes #19387, icon and full preview
render at the same time would crash.

I'm not really convinced this is thread-safe, but on the other hand also
not sure regular preview render is really thread-safe yet.

Fix python error in boids panel, missing variable psys.

Fix #19483: error using FBX export script, diffuse_reflection
changed to diffuse_intensity.

Fix potential crash for file operators that don't define
a "path" property, now it will just give a warning.

Fix compile problem on OS X Snow Leopard. The Mac code for dynamic
library loading was using some non-public OS X functions, which give
linking issues for me. Since OS X 10.3 standard unix dlopen() is
supported, so I just removed this code, we don't support earlier
versions anyway.

Fix drawing of MENU buttons with only an icon, was not aligned right
and showing unneeded triangles (+ buttons in Boids Brain).

* Copy() -> Clone() (even though these hopefully will be obliterated from extern/ soon)
* remove reference to docs SConscript
* python dbg commit - somehow this one was left uncommitted when I was working on r23465 and r23464

File paths: use release/ for scripts if possible again, this got
changed with the file path changes, the reason to check this first
is that it allows to edit py scripts without having to run the
build system for each change.

Fix #19479: ctrl+N could temporarily freeze the window when user
preferences were saved from a separate window. Missing transfor of
active window state to the new window.

Fix #19477: transform manipulator did not work correct with
quad view, got wrong context.

Fix #19468: particle mode crash in transform, when there are
no editable particles.

Fix #19453: rendering with mesh in edit mode would put the object
partially back in object mode, disabling e.g. X delete.

Fix #19351: items in outliner disappear prematurely. Note icons
still disappear too soon, but this is an issue in the icon system,
same happens on all buttons, will have a fix for this later.

RNA
* Move mesh API functions to mesh_data.c, would like to keep
RNA layer fairly thin, any non-trivial functions shoud be
in their modules.
* Replace mesh.create_copy by generic id.copy.
* Fix #19250: Mesh.add_geometry() in editmode fails silently,
now gives an error.

svn merge -r 23207:23528 https://svn.blender.org/svnroot/bf-blender/trunk/blender

missing Del key in the keymaps where Xkey was used

add temp defines to keep the game engine building, should be fixed properly.
fix implicit declaration too.

File Browser fixes:

* The code to draw only visible items was not working, giving slow
performance with many files (bug #19469).
* Fix detailed list display on non-windows, would give overlapping text.
* Fix folders with many files not displaying all items, changed short to
int in various places, was overflowing.
* Recreate layout on area resizes, file view gets out of sync otherwise.
* Workaround for v2d height not being correct with image display due to
scrollers.
* Fix view2d code to compute minimum scroller size, this would make the
scroller go outside of its bounds.

jpeg2000 presets were broken.
