The original version of extresist only worked with 4-terminal FET
devices, and handling of devices with fewer terminals was ignored,
and never properly dealt with. This commit fixes the issues with
devices such as diodes that have fewer terminals.
ResTriangleCheck(). By using hash tables, I reduced
ResParallelCheck() from O(N^2) to O(N), and I reduced
ResTriangleCheck() from O(N^3) to O(N^2); however, it is a bit
better than that because previously there was an N^2 loop over
items in the same list, so if one list happened to be very long,
then N^2 would be huge; whereas now the N^2 is the length of two
lists multiplied together, where both lists would have to be very
long to have the same performance impact. It appears that long
resistor lists are pathological and rare. For an example
pathological case, the extresist runtime has been reduced from
hours to seconds.
All naked access to `ti_client` now uses the function-like-macro
to encapsulate this action. This macro existed before this just
makes all sites utilize it.
Added additional INT and PTR variants to remove the programmer
load on thinking about casing and casts polluting the point
of use. So the use now looks cleaner.
Equivalent prototypes:
void TiSetClient(Tile*, ClientData)
void TiSetClientINT(Tile*, intptr_t) /* pointertype */
void TiSetClientPTR(Tile*, void*)
ClientData TiGetClient(Tile*)
intptr_t TiGetClientINT(Tile*) /* pointertype */
void *TiGetClientPTR(Tile*)
Looks to be used as integer bitmask which is flagged by compiler warning
as dubious, when using compiler provided type 'bool' from stdbool.h
in C99 instead of unsigned char type.

transferred when doing a node merge, which can cause named
terminals to get lost, because there is no longer a node with
a name corresponding to the terminal. The node gets a default
name which is not the terminal name, and the netlist is broken.
text formatting. Made one critical correction to ResGetDevice() to
pass the device type; otherwise, devices on different planes (e.g.,
MiM caps) with the same coordinate will always return the device on
the lowest plane, leading to incorrect results and an eventual crash
when the device record is free'd twice.
the last commit, unfortunately. Thanks to Matt Guthaus for alerting me
to this. Also updated parts of the extresist code that remove the
dependence on ResConDCS; this is a minor update and should not affect
the operation of extresist. It is preparatory to doing more work to
support additional device types like capacitors, bipolars, and diodes.
simple FET device in extresist. Also: Extended the bloat-all CIF operator
again, allowing the trigger layer for the bloat operation to include both
CIF layers and magic layers (previously only magic layers were supported).
This extension is possible due to the previous extension allowing the
trigger layer and bloating layers to be on separate planes. This operator
extension is useful for tagging geometry that is in the proximity of, but
not overlapping, geometry on another plane.
