Stephen Williams e5f68d7c89 Handle dynamic queue objects in event context
In the rare cases where DARRAY signals are in the network, handle
them by creating the proper ivl_nexus_t node. This also implements
the receive of vvp_object_t objects bu vvp_fun_anyedge_sa. This
together makes it possible for IVL_VT_DQUEUE objects to be in
wait lists.

This fixes #412

Thoroughly fix parallel installation issues
In PR #300, @xdch47 pointed out a stable way to fix parallel
installation problems.

This fix applied the method, thanks!

Fix install missing file bug in PR #300
When installing tgt-stub and tgt-vhdl, due to the wrong target
path, the install scripts can't find the file to be installed.

The missing file is: stub.conf, stub-s.conf, vhdl.conf, vhdl-s.conf
Changed to right path fixed this problem.

Thanks @minux help to fix.

Stephen Williams befc91340c Parse and elaborate unique and priority case statements
The unique, unique0, and priority keywords can decorate case statements
to tell the run time (or synthesis) to do extra tests (or make extra
assumptions). These tests are not implemented in the vvp run time, but
now the decorations make it to the code generators.

Cary R d6b6b76015 Update header files to use a more standard name to prevent rereading
This is from github report #16. There are likely a few more issues

Stephen Williams d5fb0f4344 Handle some tricky conditions assignments to parts.
When for example assigning to foo[<x>] within a contitional, and
doing synthesis, we need to create a NetSubstitute device to manage
the l-value bit selects.

Larry Doolittle e221a8ced9 Rearrange compiler warning flags
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.

Larry Doolittle 642acb4082 Clean up some more sign-compare issues
The only known problems left are in files imported from gtkwave,
if not for them you could turn on -Wsign-compare.

Assumes c99 for c code, so the scope of for-loop indexes can be made sane.

Stephen Williams f8dc430fe5 Add synthesis support for casez statements.
This generates an EQZ LPM device that carries the case-z-ness to
the code generator.

Also add to the vvp code generator support for the EQZ device so
that the synthesis results can be simulated.

Account for the wildcard devices in the sizer.

Stephen Williams fa8d35ae9c Support nested l-value objects
This allows for syntax like a.b.c where a is a class with member
b, which is a class with member c, and so on. The handling is mostly
for the support of compound objects like classes.
