Cycles: Report build flags used for the OpenCL kernel compilation

For now it's reported to the stdout, matching to the CUDA behavior.
In the future we can hide this into GLog logging once the kernels
are considered all stable and so.

Cycles: Shader node features are to be inherited from the base class

Fix T44894: Round two.

We cannot `direct_link_packedfile()` twice on a same address, because this tries to
map again pf->data address, which leads to nothing (NULL).

So now, since `ima->packedfile` and `ima->packedfiles` are mutually exclusive
in 'live' blender data anyway, we either read one or the other.

Tested from/to official 2.74 and current master, everything looks fine now.

Fix T40621: Tablet in walk mode fails

Add support for walk mode /w absolute pointing devices.

WM: include tablet data in WM_event_print

Fix T44747: Drag toggle /w nodes (glitch)

It was possible to perform actions while performing a drag-toggle.

Cleanup: doxygen comments

Fix for leak in BM_uv_element_map_create

Also correct over alloc and redundant alloc.

Fix T44892: Cursor warp, invoked outside the area

If an operator starts outside an area, don't use warping.
(problematic for menu's).

Fix vertex slide regression /w rotated objects

Fix T44894: Broken packed image import from older .blend file.

rBe5fbeba0b3a6e9eea not only restored forward compat, it also broke backward compat...
for no reason at all even, exising ima->packedfile is only used by read/versionning
code if .blend version is below 274.4 (i.e. no multi-image packing exists).

Improvements to the Freestyle Python API (needed by the SVG Exporter)

This patch adds some new functionality to the Freestyle Python API, notably:

- MaterialBP1D, checks whether the supplied arguments have the same material
- Fixes a potential crash in CurvePoint.fedge (due to NULL pointer)
- Makes (error handling in) boolean predicates more robust
- Adds a BoundingBox type, to make working with bounding boxes easier
- Adds several new functions (get_object_name, get_strokes, is_poly_clockwise, material_from_fedge)
- Adds a StrokeCollector StrokeShader, that collects all the strokes from a specific call to Operators.create()
- Adds hashing and rich comparison to the FrsMaterial type

These new features (most of them, anyway) are needed for making a more robust SVG exporter that supports holes in fills.

UI: comments (doxygen tweaks)

BGE Cleanup: Removing flen variable where it is not used

BGE Cleanup: Identical code for both if/else branches

fix T44884: corrected a wrong usage of the CustomLayer API (due to a misunderstanding)

Correct own error with recent commit

Caused entering an invalid number to leak.

python tar.gz changed structure due to python.exe being added. remove /lib/ from cmake as lib and bin are both in the tar.gz
