Cleanup: Tweak operator names

Add UserPref option to change HMD device

A new file wm_device.c is added with this, think this is good to have.

NOTE: Couldn't really test if changing device actually works as I don't have one. Without a device available everything seems to work though.

Option to request interocular distance from HMD driver

Adds a new camera option to request the interocular distance (IPD) from the HMD device/driver. It's still an open design question if it's even worth to support a custom distance though.

Also hides convergence options for HMD mode, not sure if those are needed.

Show option for interocular distance for HMD mode

Just as for stereo 3D, available in properties editor, camera context.

HMD: Cleanup of CMake file

HMD: Add support of lazil loading udev library

This way we can statically link against hidapi libraries but dont'
require static linking against udev or even having specific ABI
version of this library installed on the client machine.

For now the following libraries will try to be loaded:
libudev.so, libudev.so.0, libudev.so.1 and libudev.so.2

Not future proof since it might be version 3 of udev releases
eventually, good enough for the beginning. We can simply do a
for-loop to query like 100 of ABIs.

Udev wrangler is a bit different from other wranglers we've got,
it has wrapper functions around dlopen-ed symbols, so you can't
check directly if function was loaded or not, but this is the
only way to make external libraries working fine with wrangler
without need of re-compiling the library.

HMD: Quick and dirty way to make sort of portable builds on Linux

It will require having libudev.so.1 which isn't ideal but should work for
most distros for now.

Will be worked around later with udev wrangler.

Option for HMD view shading mode

- Fixed correct event polling for all operating systems
- Fixed up openhmd cmake for windows builds

Fix inner manipulator circle not aligned to viewplane

Open/close HMD device based on session status

Fix anaglyph viewport drawing with HMD view open

Fix stopping session not exiting fullscreen

Fix camera not being reset when stopping session by closing HMD window

Reset camera on HMD session end

Added utility functions for getting/setting rotation from quaterion.

Fixed memory addressing, should work on every system now

Added check for nan events from OpenHMD
