PLI 1 was deprecated in 1364-2005, so disable by default and note that
it is deprecated in the help text.
This works round the problem that the clang linker (lld) in MSYS2 does
not support the -r option, so cannot be used to build libveriuser.a.
The clang dlltool is not compatible with the binutils dlltool. However
both the clang and binutils linkers support reading the .def file and
creating the import library directly, so we no longer need to perform
the link in two stages.
Now we publish releases on GitHub, we need to commit the file to the
repository when making a snapshot or release, so we need to use a
different filename to the one that is automatically generated by
'git describe' (which we still want git to ignore).
In addition to providing positional arguments for task and functions
SystemVerilog allows to bind arguments by name. This is similar to how
module ports can be bound by name.
```
task t(int a, int b); ... endtask
...
t(.b(1), .a(2));
```
Extend the parser and elaboration stage to be able to handle this. During
elaboration the named argument list is transformed into a purely positional
list so that later stages like synthesis do not have to care about the
names.
For system functions and tasks all arguments must be unnamed, otherwise an
error will be reported.
In addition to functions and tasks arguments can also be bound by name for
the various different ways of invoking a class constructor.

The figure_packed_base_type() method can be used to check whether a type is
2-state or 4-state at parse time. The parser no longer cares about the
specific type of a data type. The figure_packed_base_type() function is
no longer used, so remove it.

There are a couple of different functions for the different data types that
are called when the type of a signal is set. But they all effectively do
the same.
Consolidate this code by moving the common code into the main
pform_set_data_type() function.
This allows to remove most of the type specific functions and eliminates
some duplicated code. It ensures consistent and data type independent
behavior at the parser level. Something that will be required to eventually
support type parameters.

Currently only dynamic arrays and queues of atom2 and vector types are
supported. Add support for packed arrays. Since these three types are
essentially handled the same internally supporting this only requires to
allow to elaborate a packed array base type.
Factor out type elaboration into a helper function that can be shared
between the elaboration of the base type of a dynamic array or queue and
the type for other signals. This gives consistent behavior and will also
make it easier to support additional base types for dynamic arrays or
queues.
Note that it is not yet possible to index elements of packed array dynamic
arrays or queues. But neither is it possible to do a bit select for vector
or atom2 type dynamic arrays or queues yet. Supporting this needs some
additional work.
There is one test that declares a queue of a struct type, but doesn't use
it since it is not supported. With this change a error will generated when
trying to declare a queue of a struct. So update that test to not declare
the variable so it does not fail.

There are too many ad hoc handlers of symbol_search partial results.
Rewrite symbol_search to clean up things like partial results and
member/method detections. Use this reworked symbol_search function
to rewrite expression elaborate for the PECallFunction expressions.
With a pattern rule, the recipe will only be executed once, even when
the rule has multiple targets. Using this to handle the output from
bison is included as an example in the GNU make manual.
This fixes the makefiles so that bison-generated header files will be
regenerated if they are deleted.
The current bison (3.7) generates a *.cc file that includes the header
it generated. For parse.cc this would be parse.hh. Right now, we rename
this header to have a common name used in other files, but this results
in a compile error for the parse.cc file:
parse.cc:462:10: fatal error: parse.hh: No such file or directory
462 | #include "parse.hh"
| ^~~~~~~~~~
Fix this by telling bison to output the header file to the correct
filename in the first place so that we don't have to rename it.
(using the --defines instead of -d option).
This looks like a bison specific option not available in Posix yacc;
but looks like we're requiring bison anyway.

In PR #300, @xdch47 pointed out a stable way to fix parallel
installation problems.
This fix applied the method, thanks!

bison 3.4.1 writes the header file before the c++ file. Our makefile
rules make the header files depend on the c++ files, so we need to
fix the timestamps accordingly.
Before this patch, WARNING_FLAGS applied to both C and C++,
and WARNING_FLAGS_CXX applied to C++ only.
This patch adds a WARNING_FLAGS_CC that applies to C only.
That change should be generally useful; in particular the C
code is almost ready for -Wstrict-prototypes, which does not
apply to C++.
-Wextra (or -W) used to only apply to C++ via WARNING_FLAGS_CXX.
This patch moves it to WARNING_FLAGS, to apply to both C and C++.
Unfortunately, that triggers a ton of warnings.
For now, cover most of the new warnings up by adding
-Wno-unused -Wno-sign-compare -Wno-type-limits
to WARNING_FLAGS_CC. In the long run, I want to change the C coding
style, and take off these disable-warning flags. But those changes
can dribble in as separate commits; this patch is big enough already.
Actually fix a couple missing-field-initializers in libveriuser/veriusertfs.c.
Add properties to the classes, and elaborate expressions that
have class properties. Describe class object property references
all the way down to the stub target.
