Locks protect the std::set in each item. Devolving the mutex to the
CN_ITEM allows multiple threads to make simultaneous connections to
different items where they do not conflict.
The connectivity files were unwieldy. This separates them logically
into data, algo and items where the items classes are those that hold,
surprise, surprise, the items, lists and clusters.
Refactor the polygon event loop into its parent function to allow access
to the params structure. Active layer now updates the drawing layer for
add/cutout zones.

Dynamic casts should only be used when we explicitly check for the
resulting pointer to be NULL. Where we know the class is castable we
can use static_cast, save on overhead and ensure our resulting pointer
is non-null.
When using the board edit, align tool automatically moved footprints
instead of pads but distribute tool did not. This standardizes the
behavior.

The evaluation of count_if resulted in a 0 or 1, leading to segment zone
fills always running on single processor and the progress bar showing
incorrect status. Likely infrequently hit as only affected segment
fills.
Block rotate and mirror now work like they do in Pcbnew (that is
they're treated as part of the block move/duplicate/whatever
rather than finishing it).

If the user is carefully selecting the zone edge, we do not filter the
zone preemptively from our disambiguation list in the same manner as we
do for selecting on zone copper.

The board design settings file keeps our default values for various
thicknesses. We use this to replace a number of magic numbers with the
defined value to help self-document the code.
The check against S_POLYGON was always false because we set the default
type to S_SEGMENT. This unifies the magic numbers to the board design
settings file
Disabling the grid should leave the snapping in place. But our disabler
returned the current point as closest, effectively always ensuring the
cursor position was the closest snap. This only uses grid when
requested.
This is temporary until we figure out a way to do multiple constraint
handling in GRID_HELPER or the EC_* class. This will work as long as
the EC constraint helper places the endpoint on either the primary or
aux grid.
