1) For a while now we've been using a calculated seg count from a given
maxError, and a correction factor to push the radius out so that all
the error is outside the arc/circle. However, the second calculation
(which pre-dates the first) is pretty much just the inverse of the first
(and yields nothing more than maxError back). This is particularly
sub-optimal given the cost of trig functions.
2) There are a lot of old optimizations to reduce segcounts in certain
situations, someting that our error-based calculation compensates for
anyway. (Smaller radii need fewer segments to meet the maxError
condition.) But perhaps more importantly we now surface maxError in the
UI and we don't really want to call it "Max deviation except when it's
not".
3) We were also clamping the segCount twice: once in the calculation
routine and once in most of it's callers. Furthermore, the caller
clamping was inconsistent (both in being done and in the clamping
value). We now clamp only in the calculation routine.
4) There's no reason to use the correction factors in the 3Dviewer;
it's just a visualization and whether the polygonization error is
inside or outside the shape isn't really material.
5) The arc-correction-disabling stuff (used for solder mask layer) was
somewhat fragile in that it depended on the caller to turn it back on
afterwards. It's now only exposed as a RAII object which automatically
cleans up when it goes out of scope.
6) There were also bugs in a couple of the polygonization routines where
we'd accumulate round-off error in adding up the segments and end up with
an overly long last segment (which of course would voilate the error
max). This was the cause of the linked bug and also some issues with vias
that we had fudged in the past with extra clearance.

You can now enable and disable snap to grid when drawing/editing across
all apps. You can also tie snap to grid to the visibility of the grid
to allow rapid enable/disable via grid display.
This forward declaration doesn't match the class defined inside the
function, so the friend declaration does nothing. The friend declaration is
also unneeded, because the function is a member of the class (and so are
types defined within it), so these already have access to private members.
* Split up the thirdparty code into the thirdparty folder (#3637)
* Create a new kimath static library containing all the math functions
This is part of cleaning the build system for #1906.
We have forbidden lists maintained in 3 separate locations. This causes
a bit of confusion as to which is correct.
This makes the list uniform but remains to place the character set in a
single location.
Some microwave inductor lengths cause invalid outputs
for the calculations, which causes jagged outputs.
* If the request length is such that four arcs and no straight
segments is too long
* If the length is such that an N-turn coil is too short, but
an N+1-turn coil is too long. This can happen when the coil
count is small.
This patch doesn't fix the underlying geometric issue here - fixing
the first requires a numerical method, and fixing the second probably
needs an iterative approach. Both of these could benefit from
a refactor.
However, this patch does prevent the tools producing invalid outputs,
which can sometimes be quite subtle mistakes if the "jags" are small.

Where we can get away with lower segment counts (localizing an anchor),
we keep the low-def 16 segment count. Intermediate values and values
that are visible to the user are set to high definition. Most are
simply hints to the inflation correction but where they show, the user
show see smooth lines.
This removes the existing constructors so that all parsing must
be explicit and callers are made aware that they need to think
about illegal characters, malformed ids, etc.

The general idea is to support user-units inheritance. The
UNIT_BINDER allows wrapped controls to inherit units from their
parent dialog, while KEYWAY_HOLDER and DIALOG_SHIM allow child
KEYWAY_HOLDERs or DIALOG_SHIMs to inherit units from their
parent.
The GetUserUnits() method signature has to move to KEYWAY_HOLDER
rather than KEYWAY_PLAYER (where it makes more sense) as it’s the
only common ancestor of KEYWAY_PLAYER and DIALOG_SHIM.
As long as we'll be using the UNIT_BINDER more widely, it also
makes sense to move evaluation and validation into it.
This commit also provides eeschema’s DIALOG_LABEL_EDITOR and
pcbnew’s DIALOG_TRACK_VIA_PROPERTIES and DIALOG_SET_GRID as
models of how to use the new user-units inheritance, eval, and
validation.

(cherry picked from commit c8bc53e)
When a new footprint is created, CreateNewModule() added it to a dummy
board in the footprint editor. If a footprint was indeed created (the
action has not been aborted) then the dummy board was cleared,
destroying the just created footprint. Also, the new footprint is later
added with AddModuleToBoard() call.
