1) Corrected spurious error messages about cells already existing
in GDS when using "flatten" or "flatglob".
2) Fixed handling of resistance as a subcircuit parameter
3) Added area and perimeter resistance for a device; this is done
through the "devresist" statement in the tech file, which is an
extension of the original "fetresist" statement. Where "fetresist"
only supported type "linear", "devresist" supports types "area"
and "perimeter".
4) Support for CDL syntax, including generating subcircuit-like
parameters for components starting with SPICE-standard prefixes
like M, R, C, etc., adding "/" between pins and subcircuit name,
and saving the file as ".cdl" instead of ".spice".
5) Estimated L and W for devices whose geometry is complex and do not
reduce to a simple rectangle. L and W are estimated as the square
root of the area.
6) Changed the method of extracting L and W for diodes to use the same
method as capacitors. Note that diodes are not usually specified
by L and W, but if they are, this will produce the right result.
7) Corrected the reported filename and line number when printing error
messages related to errors inside a technology file, when the
technology file uses "include" to combine multiple files.
prefix when doing a reentrant load, causing include files to not
be found. Fixed a divide-by-zero issue that occurs when some
tech file sections are not loaded to the abovementioned error.

contacts) take default values from the DRC section. Since both
are in lambda, but the DRC section uses a two-part integer and
modulus representation, if default values are taken before
scaling, the LEF layers may get rounded values. This has been
solved by marking values with -1 to indicate that they require
defaults, and then set those defaults (from scaled DRC rules)
after scaling all other tech values.
This commit makes the code (mostly) C99-compatible, enabling to compile
it without the -Wno-error=implicit-function-declaration flag. This
way, Magic becomes usable on arm64 architectures, specifically on Apple
computers with M1/M2 SoC.
tech file format "version" section. This can be used to specify the
version of magic that must be used to be compatible with the tech file.
This effectively supercedes the technology version number. (2) Changed
the behavior of "make" to set the version and revision numbers on doing
"make" instead of "configure". This allows the version to update
correctly after doing a "git pull" followed by "make" without doing
"configure" in between. (3) Fixed a couple of issues that were flagged
as compile-time warnings.
