not be seen during hierarchical processing, causing the substrate
to get split into several names that may conflict in the netlist.
At issue is the fact that ExtLabelRegions() will not attach a
default substrate label to a default substrate region. This may
need further untangling, as extFindNodes() will set the default
substrate node and is sometimes followed by ExtLabelRegions(),
which will label it. Any place ExtFindRegions() is called, this
could be an issue.

issue stemming from this was reported in github issue #203 by Anton
Blanchard. This commit fixes that error.
restricted to its original intent, which is to replace the long name
formed from the plane short name and the "minfinity" coordinate.
This avoids issues with conflicting substrate names derived from a
real layer such as pwell. Also, the global substrate node name now
returns the variable name without the "$" in front if the variable
has not been set to anything. This avoids potential syntax errors
in the netlist.
unique" code. It was using DBEraseLabelsByContent() which would
erase all matching labels, and could potentially erase labels that
were still remaining on the list being processed, causing a segfault.
Also corrected minor errors identified by valgrind during debugging
the above-referenced problem.
