Fix for heap-use-after-free happening in GHOST_EventManager.

Issue was that dispatchEvent might call removeWindowEvents/
removeTypeEvents which will delete the event before we can do so.

To address this, handled events are now put in a separate list.

Reported by psy-fi and reviewed by brecht in IRC.

Changes to rename_id function:

* Don't copy name before entering new_id function. new_id does that for
us already.

* Take a main argument to make the function possible to use with
different databases

* Append BKE_ to rename_id

Addendum to previous GHOST commit: remove redundant check.

Minor UI incosistency reported by erickblender on irc. Twist brush is
renamed to Rotate to match the tool name.

It is not actually compulsory that the two must match since users can
change the name of a brush arbitrarily but at least try to have
consistent naming in our defaults.

Fix memory leak in GHOST Event Manager.

The events are allocated on the heap, then pushed on a stack. Before
being processed, they are popped from the stack, and deleted after
processing is done. When the manager is destroyed (e.g. application
closing), any remaining event in the stack is detroyed.

Issue is that when the "application closing" event is processed, it is
never freed, because the manager gets destroyed before the call to
`delete` is made and the event is not on the stack anymore.

Now events are left on the stack while they are processed, and only
popped and deleted after processing is done.

As a slight bonus refactor: use void as return type for dispatch events
functions, as no caller is checking the return value, and it is not
clear what it means (suggested by the reviewer).

Fix T47064: Change Audio defaults to 48 kHz

Historically blender had an audio sample rate of 44.1 kHz as default which is mostly popular because it's the sample rate of audio CDs. Audaspace kept using this default from the pre 2.5 era. It was about time to change to 48 kHz, which is a more widespread standard nowadays, especially in video. It is the recommended sampling rate of the Audio Engineering Society.

BMesh Path Select: Face Stepping Option

Supports diagonal paths for verts and faces,
Selects edge-rings with edges.

BMesh: BM_loop_share_edge_check utility func

Split id->flag in two, persistent flags and runtime tags.

This is purely internal sanitizing/cleanup, no change in behavior is expected at all.

This change was also needed because we were getting short on ID flags, and
future enhancement of 'user_one' ID behavior requires two new ones.

id->flag remains for persistent data (fakeuser only, so far!), this also allows us
100% backward & forward compatibility.

New id->tag is used for most flags. Though written in .blend files, its content
is cleared at read time.

Note that .blend file version was bumped, so that we can clear runtimeflags from
old .blends, important in case we add new persistent flags in future.

Also, behavior of tags (either status ones, or whether they need to be cleared before/after use)
has been added as comments to their declaration.

BMesh Path Select: Add checker-select options

Allows to quickly select alternate elems in a path (matching checker-deselect options).

- adds redo support to MESH_OT_shortest_path_pick, allowing for other options.
- de-duplicates code between 2x path select operators.
- expose 'Topology Distance' property for path picking.
- remove unused 'extend' property.

BMesh: extract int/bmesh element access funcs.

Support getting an vert/edge/face from a single index, useful for operator redo.

WM: add checker_interval utility functions

Move generic operator props into own file

This is unrelated to core operator internals, so move into own file.

Fix for error w/ QtCreator project builder

cmake_qtcreator_project.py now takes a '--build-dir' argument.

Since introduction of argparse, accessing last argv from project_info is no longer working.
Now require a call to project_info.init before use.

OpenGL: stipple support added to basic GLSL shader

The is intended to replace the deprecated glPolygonStipple() calls with a shader
based alternative, once we switch over to GLSL shaders.

CMake: Disable some features when using MinGW and full cmake config

CMake: Fix errors building by MinGW

Some libraries are nto updated for MinGW hence build system
needs some exceptions for this compiler.

Support custom project names

BMesh: add checks for duplicates in a face

These could go un-noticed, causing errors later on.
