Graph Editor: Snap and Mirror keyframes now respect Cursor X in Drivers mode

When using the "Current Frame" options for these operators, the Cursor X value
will now be used instead of the current frame. Perhaps the labels could be changed
too, but for now, I guess this will be good enough.

Graph Editor: Adjusting Change Frame and Jump to Keyframes operators to work with Drivers Cursor

Fix T46599: Copy Rotation behaves erratically when Use Y is disabled

When the "Use Y" option in the Copy Rotation constraint is disabled, the constraint
behaves eratically when rotating all the target on all axes at the same time.
This is partially to be expected due to the way that euler rotations work
(i.e. the rotation orders stuff - you should use a rotation order based on most to
least important/significant rotations). Hence, by locking Y, you're causing accuracy
problems for Z.

What was not expected though was that changing the rotation orders on the objects
involved (for the record, it's the constraint owner that counts) did nothing.
It turns out that for objects, the rotation order settings were getting ignored!
This commit fixes this problem, and this particular case can be resolved by using
"XZY".

Notes:
* Since all object constraints were previously working on the assumption that they
used XYZ (default) order, it is possible that this change may have the unintended
consequence of changing the behaviour of some rigs which relied on the buggy
behaviour. Hopefully this will be a rare occurrence.

Graph Editor: Allow "cursor x" to have fractional values when working with Drivers (T46004)

When working is the Graph Editor it can be very important to be able to work with fractions
(sub integers), especially when working with Drivers. Currently the "Cursor Y" is hooked up
to "cursor_position_y" which allows fractions but "Cursor X" is directly hooked up to
"frame_current" which is an integer.

This commit adds initial support for this feature.
* When in Drivers mode, the x-part of the cursor is mapped to a new "cursor_position_x"
value which can have fractional values. Animation mode however remains mapped to frame_current

* This commit only adds the UI/property/drawing tweaks needed to support this.
Many operators still need to be modified to consider this value instead of the
current frame, for this to be more useful.

Fix: Missing update after scrubbing time in Graph Editor

Sometimes the timeline header didn't update after time-scrubbing in the graph
editor ends, leaving the "Pause" button visible until the next refresh of the
timeline (e.g. on mouse over)

Fix: X-axis values in Graph Editor should not be displayed as timecodes in "Drivers" mode

Alternative presentation for interpolation indicator for discrete properties

Graph Editor: Disable interpolation setting for enum/boolean FCurves, as no interpolation is performed on those

ndof: rework Mac driver glue

Load driver dynamically at runtime instead of weak-linking the
3Dconnexion framework. Driver no longer needed at build time!

Works with really old drivers (as in PowerMac old), more recent
versions, and the latest which allows us to process events on a
separate thread.
