Fix use of uninitialized variable in undo system.

WM: pre-fill bug-reports

D4507 by @LazyDodo w/ edits & moved into own module.

Build environment: require Alsa/OSS/PulseAudio backends for OpenAL on Linux.

Otherwise we can silently build an OpenAL that can't actually playback audio.

Fix T57305: NDOF frozen w/ lock view to camera

This effectively reverts 030297209f2508a and 785e8a636a2939,
which caused this issue.

Merge branch 'master' into greasepencil-object

BMesh: make edge winding from face optional

Broke uv-sphere creation, further it might be a problem
for script authors expecting matching edge order for duplicated content.

Now only apply this when duplicating via the operator.

Fix Cycles interface after 3017d88aec7f

Fix T62487: Flipped normals extruding edge loop

BMesh: utility function to swap edge verts

Needed so we can control the winding of extruded faces.

Fix T62484: Mesh undo ignores selection mode

Fix T62524: Popover w/ keep-open moves on cursor motion

Cleanup: rename uiBlock.mx,my to bounds_offset

Use a name that related to block bounds calculation
(mx/my are typically used for mouse x,y).

Cleanup: use unpacking & generators to build classes

No reason to make a classes tuple then manipulate it when
everything can be declared inline.

UI: avoid sub-classing mix-ins for user-prefs

Also remove redundant staticmethod use.

UI: rename PresetMenu to PresetPanel, move to bl_ui.utils

Confusing to call a menu a panel when subclasses need to define
panel specific variables.

Avoid having bl_ui depend on bl_operator module too.
Since this isn't an operator, add utils modules for shared types.

UI: tweak check for sequence length

Slightly less work to check if it's None
(no need to inspect the listbase).

Cleanup: redundant staticmethod use

staticmethod shouldn't be used unless it's necessary,
in that case a comment should be included especially when
subclassing non-staticmethods from RNA.

Cleanup: redundant bpy.context access

Cleanup: remove unused menu

Cleanup: pass context to draw method instead of accessing from bpy

Allows for context overrides/mocking.
