PyAPI: add BPY_execute_string_as_string

Utility to execute a string and get the resulting string,
matching BPY_execute_string_as_number.

Not used just yet but generally useful function.

Object Mode: Add stencil test to remove object outlines inside the silouhette.

It also adds nice occluded silouhette information for selected objects that are behind visible objects.
This methods is really heavy because it needs to render the wires twices.

Fix shader compilation.

GPUTexture: Add support for depth_stencil textures.

Eevee: Initial commit

Basic support for lamps. Only diffuse.

Draw Manager: Created a general fullscreen shader.

Cleanup: use return args last and 'r_' prefix.

Gawain: remove PER_THREAD macro

This attempt at TLS was leftover from an earlier prototype. It never worked with Blender's build system, and was defined to just exist, not to actually do anything.

Add tabs as standard button types

NOTE: This is really a backend-only implementation, nothing is changed in the UI

Adds a tab button-type and the basic drawing and handling code for it.
More work needs to be done on it, but idea is to get in ready for usage in the
topbar.

Merge branch 'master' into blender2.8

Cleanup: Use proper indentation

Cycles: Cleanup, indentation

Refactor writefile handling of data-blocks.

Instead of calling a function looping over whole list of a given ID
type, make whole loop over Main in parent function, and call functions
writing a single datablock at a time.

This design is more in line with all other places in Blender where we
handle whole content of Main (including readfile.c), and much more easy
to extend and add e.g. some generic processing of IDs before/after
writing, etc.

From user point, there should be no change at all, only difference is
that data-block types won't be saved in same order as before (.blend
file specs enforces no order here, so this is not an issue, but it could
bug some third party users using other, simplified .blend file reader maybe).
