Having an invisible gizmo caused event handling problems (see: T56603).
This is hard to avoid since gizmos are similar to buttons in the way
they have priority over the regular keymap.
Transform events use tweak so events to fall though to the general
view 3d keymap (for cursor placement for eg).
Users can select the main unit they want to use now.
Previously the displayed unit always depended on the magnitude of the value.
The old behavior can be restored by switching to the "Adaptive" mode for length, mass and time units.
Meters, kilograms and seconds are the default units for new and old scenes.
The selected unit is also the default unit for user input.
E.g. if cm is selected, whenever the user inputs a unitless number into a field of type length, it will be interpreted as cm.

This commit make the Xray option for the wireframe different from the other
shading mode. This makes it possible to rapidly switch between wireframe +
Xray and Solid mode without Xray.
Xray alpha is also decoupled.
Both variables are duplicated and exposed separately through RNA.
* Proportional pie menu at shift+O.
* Snap pie menu at shift+S.
* Pivot pie menu at comma. Previous comma, ctrl+comma, period
and ctrl+period shortcuts for specific pivot types were removed.

This makes the Edit Mesh display settings common to all objects. They can
also be set differently per viewport.
Modifying extra data (seams, sharp edges etc...) will no longer set them
automaticaly visible.
Bumping version because we need to force set all extra draw options for
older files.
We now treat Xray as being the mode where Limit selection to visible is off.
If Xray is OFF, Limit selection to visible is considered ON.
To allow 'see through wires' with solid shading (not Xray shading) we still
draw solid shading if Xray is ON with Xray Alpha set to 1.0.
