This is the first step to allowing non-segments in the line chain.
External routines cannot be allowed to change the line chain without
going through the internal routines. To accomplish this, we remove the
Vertex() and Point() access routines and only leave the const versions.
Transformations are given for both points as well as the chain itself.
Pads not on copper layers now do not have a netname, and are no longer taken in account in connectivity.
Especially it avoid creating useless rats-nests for these pads.
This removes the remaining hard-coded segments counts and replaces them
with the relative error calculation where the segments per arc is
determined by the maximum error we allow (smaller arcs = fewer segments)
Give the user the option of cancelling a file open if there are
segment zones; otherwise they're converted to polygon fills.

the filled areas can use a hatch pattern (crossing lines) using square holes.
The zone filler removes too small holes (truncated holes) from hatch pattern.
It avoid to create small holes when a hole pattern is truncated by the filled area base shape.
Commit 6006703798 fixed a crash but broke the filled zones changes detection.
Filled zones were always seen as not up to date due to the fact the filled areas were cleared too early.
The up to date detection is also optimized: the old filled polygons are no longer stored.
Instead of, the MD5_HASH is calculated and stored before clearing the filled polygons.
Previously, in many cases the selected zone was refilled on exit selection, even if the zone was not modified.
This is annoying, because the zone fill can be really time consuming, and cannot be called without a good reason.
Now the refilling is made only if a zone parameter is actually modified.
In the past, the ZONE_CONTAINER::GetPosition() member
returned a reference to a wxPoint, in accordance with the
BOARD_ITEM interface. This meant that ZONE_CONTAINER had
to reinterpret_cast a VECTOR2I (its internal position data) to wxPoint,
which was possible only due to fortunate memory layout.
This interface was changed to return wxPoints by value in
commit a4528988ca, and the normal (wxPoint) cast was used instead.
Thus, we can now also remove the dire warnings and static_asserts
used to ensure the now-unused old method was correct.
SEGZONE types were confusingly named PCB_ZONE_T. Zones in pcbnew are
now _only_ PCB_ZONE_AREA_T, so we name segzone types PCB_SEGZONE_T to be
clear.
This also removes processing of the SEGZONEs from connectivity
calculations.
Missing types were handled by the superclass (in the case of zones)
PCB_CONNECTED_ITEM, which incorrectly returned "true" when testing lines
against zones.

Step 4 in the g_UserUnit eradication effort.
Also removes a couple of conversion routines that were close
enough to extinction.
