Code cleanup:
* Some typo fixes.

Fix compilation error, missing size_t declaration

BGE: Updating the bge.logic.expandPath() documentation to better reflect its current behavior.

Merging r59083 through r59103 from trunk into soc-2013-depsgraph_mt

add support for loading 8bit BMP images

Fix #36451, Particle system crashes blender. The psys_render_restore function was accessing the psys->frand random number array, but since the particle modifier is disabled this array does not get
initialized. Added a sanity check to skip disabled particle systems in BI render. (why wasn't this done before?)

change VIEW3D_OT_camera_to_view_selected poll function so it can be called from a script (without a view3d).

BGE: Adding a GPU Latency profile category to represent the CPU time spent waiting on the graphics card.

fix for bug in rip tool, isolated verts would remain selected after ripping.

fix own regression, rip tool wasn't handling selection.

switch arg order for BM_elem_select_copy(), would like to make this constant for all bmesh functions eventually.

bmesh: simplify mode check for setting the edge selection

bmesh_vert_separate: remove unused return value

bmesh_edge_separate: avoid counting radial loops when splitting edges, we only need to check if the edge is boundary or not. will speedup edgesplit modifier a little.

Fix [#36439] Switching windows on Win7 x64 under certain outliner conditions will cause crash

Fix crash happening in particle code caused by non-reentrant qsort()

Particle system code used global variable to sort hair by orig index,
which is not safe for threading at all.

Replaced this with usage of reentrant version of qsort, which is
now implemented in BLI. It was moved from recast navigation code
to BLI, so more areas could use it (if needed).

Use atomic operations instead of spin lock for threaded update

This replaces code (pseudo-code):

spin_lock();
update_child_dag_nodes();
schedule_new_nodes();
spin_unlock();

with:

update_child_dag_nodes_with_atomic_ops();
schedule_new_nodes();

The reason for this is that scheduling new nodes implies
mutex lock, and having spin around it is a bad idea.

Alternatives could have been to use spinlock around
child nodes update only, but that would either imply having
either per-node spin-lock or using array to put nodes
ready for update to an array.

Didn't like an alternatives, using atomic operations makes
code much easier to follow, keeps data-flow on cpu nice.

Same atomic ops might be used in other performance-critical
areas later.

Using atomic ops implementation from jemalloc project.

Followup for r58992, fixing user decrement error

Some places like proxy rebuild didn't increent
custom shape user counter which lead to user
decrement errors later when freeing pose channels.

Try to keep custom object counter relevent, but
some corner cases might still be missing.

GPL V3 license, which will be valid for the binary releases.
(Because Blender links with the Apache2 license).

Cleanup of this directory will happen before official release.
