Additionally the HierName's hierName1 and hierName2 arguments have been
made 'const' to help convey the receiver can not modify the referenced
data passed.
warning messages about ports being electrically connected when
those ports have names that match under rules of case-insensitivity,

SPICE netlist, which is case-insensitive. Also: Corrected a crash

redundant (same name, different net). Previously, the method was
to keep the first such node and ignore all others except to add
their resistance and capacitance to the original node. This
prevented routines like "def write" from enumerating all nets
unless they had unique names. The new method keeps the additional
records including the node location where they can be found by
EFNodeVisit(), but flags them with EF_UNIQUE_NODE so that routines
like ext2spice or ext2sim can choose to ignore them. This implies
that this method could be used to reimplement "extract unique"
within "ext2spice" or "ext2sim" without altering label text. This
has not yet been implemented.
a routine that should have been called with a NULL argument, but
instead was called with no argument, making the behavior system-
dependent. Revised the parsing of the "defaultareacap" and
"defaultperimeter" statements in the tech file, such that the short
version of both statements gets automatic handling of the substrate
and isolated substrate areas; this goes back to the recent change
in extraction behavior to redefine the "substrate type" (e.g., pwell)
during extraction as defining isolated substrate areas, and not the
default substrate. The earlier code change dealt with problems
related to extracting nodes and regions, but did not consider how
parasitic capacitance was affected. This commit resolves that issue.
