Unlike translating existing nodes [which disables cursor wrapping and
enables edge-panning instead since rBSa1cc7042a74], adding new nodes
would still show the old behavior of cursor wrapping.
This has been disabled for the case when the node whould be added
outside (due to menus overlapping other editors).
Now enable edge-panning for adding new nodes as well and make sure
this only starts once the mouse has returned into the inside rect once.

This patch makes the background grid of the node editor a grid of dots
instead of lines. This makes the background look a bit more subtle and
reduces visual complexity. The dots are meant to provide a reference
when panning and zooming. Based on the design of @pablovazquez, and
a patch originally authored by @fabian_schempp.
The "Grid Levels" controls how many levels of dots are drawn. As the
editor zooms in, the higher levels of dots fade in, making them closer
together visually. The zoom factor at which each grid starts and ends
fading in is controllable in the code, and could be tweaked further
in the future. The new default value is 7, out of a range from 0 to 9.

Ref D12950
This was reported for the Outliner.
It was possible to set 'show_locked_time' on any space (via python, not
sure if there are other ways to achieve this).
Navigating in an animation editor obviously ruined the layout in certain
Editors that are not made for this.
Now restrict syncing to editors that support it well (the ones that have
this setting exposed in their menus) and prevent setting this in RNA.

- New operator property to toggle edge panning in the keymap:
This is disabled by default to avoid edge-panning in cases where it
gets distracting, such as adding a new node. Only the explicit
translate operator(s) (GKEY or drag) have this enabled now.
- Restore the initial view rect on edge pan cancel:
The initial view rect is now stored in the edge pan operator data.
When an operator with edge panning is cancelled it can now call the
`UI_view2d_edge_pan_cancel` function to restore the original View2D
rect.
- Less delay in node editor scrolling:
Delay is useful when scrolling through long lists, such as in the
outliner, but makes node scrolling feel sluggish and unresponsive.
The lower scroll speed here makes a faster response the better option.
- Zoom influence feature:
Somewhat slower scrolling in UI-space when zoomed out. With the 0.5
zoom influence factor nodes behave as if zoom factor is halved,
otherwise it gets too fast when zoomed out. Previously scrolling would
always be constant-speed in UI space, now it's half-way between UI
space and node (view) space.
Add overlay option to disable grid drawing.
Reuse drawing code from other editors (timeline editor)
Add argument `display_minor_lines` to function
`UI_view2d_draw_lines_x__discrete_frames_or_seconds`
This way minor line drawing can be disabled and so it doesn't cause
too much visual noise. Also spacing seems to be too fine, so VSE uses 3x
what is defined in preferences.

Starts scrolling when dragging a node or node link and going outside the current window.
Largely copied from the VIEW2D_OT_edge_pan operator.
Edge panning operator customdata and supporting functions now in
UI_view2d.h, so they could be used by operators in other editor
libraries. The VIEW2D_OT_edge_pan operator also uses this customdata and
shared functions now. Operators properties can be used to configure
edge panning margins and speed for each use case, rather than using
hardcoded values.
The speed function for edge panning has been tweaked somewhat:
* "Speed per pixel" has been replaced with a "speed ramp" distance.
This is more intuitive and also creates an upper bound for the speed,
which can otherwise become extreme with large cursor distance.
* "Max speed" is reached at the end of the speed ramp.
* Padding the region inside and outside is applied as before, but both
values are operator properties now.
Node transform operator also supports edge panning. This requires
an offset for changes in the view2d rect, otherwise nodes are "stuck"
to the original view.
Transform operator had cursor wrapping categorically enabled, but this
gets quite confusing with the edge scrolling mechanism. A new TransInfo
option T_NO_CURSOR_WRAP has been introduced to disable this behavior.
The double negative is a bit annoying, but want to avoid affecting the
existing transform modes, so by default it should still set the
OP_IS_MODAL_GRAB_CURSOR flag (which then sets the WM_CURSOR_WRAP_XY
flag during modal execution).

The main reason for this change is to allow setting the

At first you could think that this refactor would not be
necessary, because `ACHANNEL_FIRST` exists already.
It contained the small y offset that all channels had.
Unfortunately, a lot of code assumed that
`ACHANNEL_FIRST = -ACHANNEL_HEIGHT`, making the
define pretty much useless. This refactor fixes that
for the action and nla editor.
As a nice side effect, this patch fixes channel box select.
Before there was always have a half-channel offset.

This affects the timeline, dopesheet, graph editor, sequencer,
clip editor and nla editor.
Removed structs and enums: `V2D_ARG_DUMMY`, `eView2D_Units`,
`eView2D_Clamp`, `eView2D_Gridlines`, `View2DGrid`.
A main goal of this refactor is to get rid of the very generic
`View2DGrid` struct. The drawing code became very complex
because there were many different combinations of settings.
This refactor implements a different approach.
Instead of one very generic API, there are many slighly
different functions that do exactly, what we need in the
different editors. Only very little code is duplicated,
because the API functions compose some shared low level code.
This structure makes the code much easier to debug and change,
because every function has much fewer responsibilities.
Additionally, this refactor fixes some long standing bugs.
E.g. when `Show Seconds` is enabled, you zoom in and pan the view.
Or that the step size between displayed frame numbers was
always `>= 2`, no matter how close you zoom in.

This is a continuation of rB7fdffd735ff24, where I separated the
e.g. frame number drawing from scrollers internally.
This patch changes the API, so that space draw handlers
have to draw these numbers explicitely.
This greatly simplifies the scrollers API for all spaces
that just need scrollers without any frame numbers.

caused redraws (for alpha fading).
Check if scrollbars are used before calculating fade.
