Cleanup, minor fixes and serious simplification of idprops.c

Mostly, get rid of id_(un)register, we can just use mere id_us_plus/min
as anywhere else in code now. Also, unlink function was not actually
used.

Fix missing handling of IDProps of nodetree's IO sockets.

Cycles: Cleanup, indentation

Cycles: Remove toolkit-specific workaround from kernel

Cycles: Only use CUDA 8.0 as officially supported one

This deprecates CUDA 7.5.

Cycles: Cleanup, don't use m_ prefix for public properties

Cycles: Fix compilation error with visibility flag disabled

Cycles: Make all #include statements relative to cycles source directory

The idea is to make include statements more explicit and obvious where the
file is coming from, additionally reducing chance of wrong header being
picked up.

For example, it was not obvious whether bvh.h was refferring to builder
or traversal, whenter node.h is a generic graph node or a shader node
and cases like that.

Surely this might look obvious for the active developers, but after some
time of not touching the code it becomes less obvious where file is coming
from.

This was briefly mentioned in T50824 and seems @brecht is fine with such
explicitness, but need to agree with all active developers before committing
this.

Please note that this patch is lacking changes related on GPU/OpenCL
support. This will be solved if/when we all agree this is a good idea to move
forward.

Alternative fix for crash displaying 'New Window' keymap item

rB870440dee910c9 just did NULL-check for Main pointer, actual issue is
that bContext pointer was NULL. This can be fixed by ensuring
PROP_ENUM_NO_CONTEXT flag is not set by calling
WM_operator_properties_sanitize when creating RNA buttons. Now, layout
previews are visible in keymap editor too.
