If we do a real drag, the timer will be cancelled. If we don't, then
the user is still holding the mouse button down and would probably like
to see the menu. Otherwise it appears the action is dropped.
The other drawing tools allow drag selection while idle. Also, it makes
it more obvious to the user when accidentally drag selecting while
routing than just doing nothing on a drag with the routing tool selected
and idle.
We were already checking zones separately (after tracks and pads); we
just weren't setting the flag that causes the COLLECTOR to also test
zone fills.

Previously, we were checking if the selection tool was the top of the
stack but this ignored many other "secondary" tools that might be
running such as the point editor. These still allow the selection tool
to handle events such as clicks. This change allows the selection tool
to handle clicks when it is the primary tool on the stack rather than
the top

This assigns the "Tab" key to a general pcbnew 45° limitation. Limit

preference so much as a temporary adjustment to tool action.

CHANGED: Multi-net highlight is now accessible when using the highlight net action
ADDED: Highlight Net and Clear Highlight actions to Net Tools context menu
ADDED: Default hotkey (Ctrl+`) for toggling net highlighting
The current and previous net highlight state are now stored and can be toggled
on or off with an action (no hotkey by default).
Highlight is now treated as a persistent state rather than a tool that is entered,
meaning there is no longer a special tool to enter in order to highlight nets.
Highlighting can be controlled while any other tool is active using the hotkeys
or context menu on a net object.

After drawing a graphic, allow the control points to persist when
exiting the tool.
The effect of this is to make the first "Esc" press a
"return-to-select-tool" event without modifying the selection or control
points from within the drawing tools. The section "Esc" press, when in
the selection tool will clear the selection and the control points
called inside the board editor.
Fix also a broken behavior: the current action was not cancelled, and if it is
called during a move items (when typing the 'T' key), items were broken.
The actual bug is the fact it is called also in fp editor and footprint wizard frame,
because it is part of EDIT_TOOL action list, common to fp editor, and should not.
But a full change is much more costly than just a filter.

It is still possible to move a pad independent of footprint through
the pad properties dialog. This is a much more conscious decision

CHANGED: There are now only two possible lock states for a footprint:
locked and unlocked. The lock state of the pads in the footprint is

After commit 9535153f9e there were no more IDs inside the legacy ID
system. Therefore the entire system for dispatching and looking up
the legacy ideas and handling those events can now be removed and

the ACTIONS class).
Loading this advanced configuration option statically will cause it to
show up in the hotkey list even when the option is disabled. Creating

from the board editor to the schematic editor.

The ACTION_MENU constructor now takes the tool as an argument,
so the call to SetTool() immediately following it can be removed

Note that we can't just update the action text with the new name,
because that is used in the hotkey list and would become too confusing
without the "Import"/"Export" text.

This simple commit makes the Pcbnew copy to clipboard operation snap the
obtained cursor position to grid before the anchors are calculated. This
is also the way the move operation has been apparently working so far.
To be clear, this will not remove all cases where the copy reference
point is not aligned to the grid (see the linked Gitlab issue for
details about the problem). This will still occur for zone outlines that
are not axis-aligned. But such behavior has been so far also present in
the moving operation, so this may be as designed.

The automatic wire tool was not working in the gridless mode because the
grid snapping on/off logic present in `EE_GRID_HELPER`, based on the
value of `m_enableGrid`, was not taking into account that another check,
but for the global KiCad setting, would be performed in the `Align()`
method, which is inherited from `GRID_HELPER`.
I've modified all tests of `m_enableGrid` value to also take the global
setting into account, and moved checks for it to `Align()` method, as
it's more consistent this way.
I've also removed an override of the `Align()` method in the
`PCB_GRID_HELPER` class, as it was made redundant by my changes.

Two issues found with the locking system used to prevent access to
stale connectivity data during the zone fill process:
1) a std::mutex has undefined behavior if you try to use it to guard
against access from the same thread. Because of the use of wx event
loops (and coroutines) it is entirely possible, and in some situations
inevitable, that the same thread will try to redraw the ratsnest in the
middle of zone refilling.
2) The mutex was only guarding the ZONE_FILLER::Fill method, but the callers
of that method also do connectivity updates as part of the COMMIT::Push.
Redrawing the ratsnest after the Fill but before the Push will result in
stale connectivity pointers to zone filled areas.
Fixed (1) by switching to a trivial spinlock implementation. Spinlocks would
generally not be desirable if the contention for the connectivity data crossed
thread boundaries, but at the moment I believe it's guaranteed that the reads
and writes to connectivity that are guarded by this lock happen from the main
UI thread. The writes are also quite rare compared to reads, and reads are
generally fast, so I'm not really worried about the UI thread spinning for any
real amount of time.
Fixed (2) by moving the locking location up to the call sites of
ZONE_FILLER::Fill.
This issue was quite difficult to reproduce, but I found a fairly reliable way:
It only happens (for me) on Windows, MSYS2 build, with wxWidgets 3.0
It also only happens if I restrict PcbNew to use 2 CPU cores.
With those conditions, I can reproduce the issue described in #6471 by
repeatedly editing a zone properties and changing its net. The crash is
especially easy to trigger if you press some keys (such as 'e' for edit)
while the progress dialog is displayed. It's easiest to do this in a debug
build as the slower KiCad is running, the bigger the window is to trigger this
bug.
