Tim Edwards be8ba09373 Created an additional argument "start" to the "slots" operator,
which adds an offset value of "start" to both X and Y from the
lower left corner of the fill area.  This allows the use of the
"offset" (from the previous git commit) to be declared on different
layers without creating an exact overlap, as is often required by
foundries for fill patterns.

Tim Edwards b493334c73 Preliminary changes to support extraction devices other than the original
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.

Tim Edwards 3d7a56ac3a Finally got around to undoing an annoyance caused by the wholesale
reduction of memory and startup time, which was to maintain only
one CIF style in memory.  The new method is just to read in and
keep the DRC CIF style separately from the output CIF style.
Because the CIF sections of the techfile are read before the DRC
sections, and the CIF DRC style is declared in the DRC section,
the CIF DRC style is read in on the fly during the first DRC
checking.

Tim Edwards bbf6008363 Enhancements to cifinput and cifoutput in the tech file: Added
option "labels ... cellid" to handle some vendor files where
apparently to get around the 30-character cell name limit, the
actual cellname is encoded on a text layer.  Added new cifop
"boundary" (no arguments) for cases where a cell abutment box
is encoded on a GDS layer;  this now translates the bounding
box to the FIXED_BBOX property, as is done with the LEF bounding
box.  Also corrected the property set function to free existing
property value allocated memory when overwriting a property with
a new value.

Tim Edwards 704f1dc69f Corrected an error that has been in the magic code forever, in which
if a GDS (CIF) layer is dependent on, and only on, a templayer or
layers that get hierarchically processed, it will not get added to
the list of layers needing hierarchical processing, and therefore
end up not being generated in the output.

Tim Edwards 66603cdb53 Corrected invalid logic in the interpetation of (cif/gds) label
options "text", "port", and "noport" in the techfile.  The
incorrect interpretation was preventing backwards compatibility,
such that ports would not be output on GDS layers if the "port"
option was not used.

Tim Edwards 9eb406ffba Implemented an idea from Staf Verhaegen to have "labels" options
"port" and "noport" in the cifoutput section to distinguish
between layer:purpose pairs for port text vs. other kinds of
text.  This allows a closer correspondence between GDS read and
write.  Note that the port writing is currently only in the GDS
write routine, not in the CIF routine.
