Fix T44003: Flatty Light: GPencil vertices and timeline keyframes black

I noticed our version code and subversion got out of sync in the past, maybe
that's what the issue was here.
Deleting the entries from the .xml makes it fall back to the default values.

BGE - new read-only attribute in KX_GameObject python api (LOD level)

Added a new "current_lod_level" property to the python api of
KX_GameObject. The property returns the current lod level of the game
object. The purpose of the property is activate logic routines only when
an object is at a certain lod-distance from the camera, avoiding to
separately recomputing the same distance in the logic script. Usage in
python script might look like:

owner = bge.logic.getCurrentController().owner
lod_level = owner.currentLodLevel
if lod_level == 0: ...do something
else: ... object might be too distant

BGE : Fix for T43724 and T41599 addObject() with KX_FontObject and
overlay scene

GetGameObjectType is overwritten in KX_FontObject to differentiate a
font object into AddNodeReplicaObject function. Now, in this function,
we add fonts in the appropriate list.

RNA: avoid inefficient array printing

Add argument to DM_to_mesh() function to take ownership over the DM

The idea is pretty simple: instead of making temporary copy of all the
related custom data layers just pass the ownership from the DM to the
mesh.

This is really handy in cases when you've got DM which you need to
convert to Mesh datablock and wouldn't need that DM after conversion
anyway.

Foe example, render database conversion, exporters and even Modifier
Apply will benefit from this option.

Add an option to mesh.calc_tessface() to get rid of polygons and loops

The purpose of this change is to add extra possibility to render engines and
export scripts to reduce peak memory footprint during their operation.

This new argument should be used with care since it'll leave mesh in not really
compatible with blender format, but it's ok to be used on temp meshes.

Unfortunately, it's hard to get scene where it'll show huge benefit because
in my tests with cycles peak memory is reached in MEM_printmemlist_stats().

However, in the file with sintel dragon it gives around 1gig of memory benefit
after removing the polys which would allow other heavy to compute stuff such as
hair (or even pointiness calculation) to not be a peak memory usage.

In any case, this change is nice to have IMO, and only means more parts of
scene export code should be optimized memory-wise.

Cycles: Free caches used by the synchronized objects

Issue this commit is addressed to is that particle system and particle modifier
will contain caches once derived mesh was requested and this cached data will
never be freed.

This could easily lead to unwanted memory peaks during synchronization stage
of rendering.

The idea is to have RNA function in object which would free caches which can't
be freed otherwise. This function is not intended to deal with derived final
since it might be used by other objects (for example by object with boolean
modifier).

This cache freeing is only happening in the background rendering and locked
interface rendering.

From quick tests with victor file this change reduces peak memory usage by
command line rendering by around 6% (1780MB vs. 1883MB). For rendering from
the interface it's about 12% (1763MB vs. 1998MB).

Fix T43959 jittering in 2D texture painting.

This is still not perfect,
but should work smoother now. Previously there was visible wobbling
while painting.

This can be included in final release.

This was never working for threaded distribution.

Initial compilation support with C++11 featureset enabled

This commit makes some preliminary fixes and tweaks aimed to make blender
compilable with C++11 feature set. This includes:

- Build system attribute to enable C++11 featureset.

It's for sure default OFF, but easy to enable to have a play around with
it and make sure all the stuff is compilable before we go C++11 for real.

- Changes in Compositor to use non-named cl_int structure fields.

This is because __STRICT_ANSI__ is defined by default by GCC and OpenCL
does not use named fields in this case.

- Changes to TYPE_CHECK() related on lack of typeof() in C++11

This uses decltype() instead with some trickery to make sure returned type
is not a reference.

- Changes for auto_ptr in Freestyle

This actually conditionally switches between auto_ptr and unique_ptr since
auto_ptr is deprecated in C++11. Seems to be not strictly needed but still
nice to be ready for such an update anyway/

This all based on changes form depsgraph_refactor branch apart from the weird
changes which were made in order to support MinGW compilation. Those parts of
change would need to be carefully reviewed again after official move to gcc49
in MinGW.

Tested on Linux with GCC-4.7 and Clang-3.5, other platforms are not tested and
likely needs some more tweaks.

Fix T43803: Crash playing smoke animation, when linked as group instance

The issue was caused by missing relations between smoke domain and flow/source
objects. This happened because smoke's modifier only iterated base objects and
ignored cases when flow/source could be linked to scene via dupli-group and
does not have real base.

The same seems to be still needed for fluid and dynamic paint modifiers,
will do it as a separate commit.
