Merge branch 'greasepencil-edit-curve' into soc-2020-greasepencil-curve

GPencil: Calculate curve when switching to edit curve mode

GPencil: Remove not needed macros and functions

Remove marco and function that was no longer needed and use
newer BKE function.

GPencil: Add update functions for the editcurve

Add new functions that will refir the curve to the grease pencil stroke.

GPencil: Remove curve flag and replace with RNA dynamic prop

We don't need this flag because we can check the struct pointer itself.

GPencil: FIx flag GP_STROKE_CURVE_MODE

The flag was set to 2^11 and it was 2^16 before. The type of the flag is short, so it was
never actually beeing set.

GPencil: Add 'select all' operator for curve

Change the 'select all' operator so that, if the stroke
is in curve edit mode, it selects the curve handles.

GPencil: Use curve fitting write data for operator

Instead of writing test data to editcurve, use the
BKE_gpencil_stroke_curve_create function to write fitted
curve data to editcurve.

GPencil: Add function to create editcurve from stroke

This BKE function uses curve_fit_cubic_to_points_fl to fit a curve
to a grease pencil stroke.

GPencil: Write operator creates two curve points

The dummy operator that writes data to the editcurve
of a bGPDstroke now writes two curve points. One for the first stroke
point and one for the last stroke point.

GPencil: Remove duplicated toggle button code

GPencil: Cleanup comment

GPencil: First test to create handles drawing

Basic structure

GPencil: Add RNA update when change handles data

GPencil: Add point index array RNA property

This property should be used for debugging purposes.
