Fix T58668: Misaligned text when editing multiple values

Fix T59448: Eevee broken Area Light shadows for square and rectange shape

Fix T58721: Keyframing one transform option reset other transforms

Use dedicated flag to tag animation just for copy-on-write synchronization,
which makes it so copies of the original data blocks gets in sync with the
original ID. This will not flush the animation update to all objects which
depend on that animation.

If such flush is required, use ID_RECALC_ANIMATION.

Curves: change default fill mode to full, increase bevel resolution.

Ref D4438.

Fix T60185: Crash on adding Inverse Kinematics

When having loops in a kinematic chain and also a IK constrain,
the solve_cycle function removes graph relations necessary to ensure
the cleanup operation was running at the very end.

Due to his Blender was crashing when some operations (the bone
constraints) accessed a pointer that was already freed.

Solved by adding more relations between crucial nodes.

UI: put Armature constraint in alphabetical order in the menu.

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.

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.
