Internal routines have no need for locking the mutex they already own.
While external routines that want to recalculate the Ratsnest do need an
exclusive lock before being allowed access

Just testing a single point to find copper that is outside the board works
until the arc->segment conversion moves the board outline just enough to
have the filled copper slightly (few IU) outside of the converted outline.
Instead, we do an expensive check of comparing the size of the
intersection between the island and the island's intersection with the
board. If the intersection is at least half as large as the original
island, we can say with certainty that the island is inside. The margin
could be much smaller than half but this preserves the intent without
picking an arbitrary number that might be violated

The polygon conversion algorithm mistakenly stored the stroke width of
filled polygons in an integer variable. As a result, all stroke widths
were rounded down to the next smaller integer mm size. This commit changes
the types in the relevant functions and variables from int to double.
Also ensure that calculated areas for island removal are absolute.
The on-outline zone can happen when the clearance to the edge is
particularly small.

The lib table returns a properly sorted list of libraries already, which
we just iterate through. A std::set is a sorted collection, but uses a
different sorting function than the lib table, so appending to a
std::set breaks the initial sorting that was done already.

It is hard for a user to tell what is going on when their zone
just doesn't fill at all. We catch isolated areas in the DRC so
we can just leave them alone here until the zone has at least one
non-isolated filled area.
Also change default back to always remove islands to reduce confusion

We call 'RecalculateRatsnest' in multiple locations, this will
invalidate various pointers needed by VIEW::Redraw(). When this is
called through the normal connectivity routines, we have the mutex
locked to prevent conflict but we've added more locations that update
just the Ratsnest. The std::adopt_lock should take over the existing
lock when needed
