Stephen Williams 3c2fb6a601 Fix dynamic array assignment to make a copy of the rvalue.
IEEE Std 1800-2017 Section 7.6 Array assignments

Assignment of a dynamic array creates a duplicate of the source,
so that assignments to the copy don't impact the original. Handle
all sorts of dynamic array base types.

Lars-Peter Clausen 1ec5a441f3 tgt-vvp: Remove (almost) empty file vector.c
Since commit 62fce50f8c ("Remove dead code for allocate_vec handling.")
vector.c only contains the license header and some include directives
but no actual code.

Remove the file.

Cary R 112ebb48d8 Add file/line information to procedural warnings and darray fixes
When -pfileline=1 is used the queue procedural warnings have file
and line information added to the messages. Also switch the trace
debugging to be off by default.

Also, Add some preliminary missing darray functionality.

Martin Whitaker 9d15b771b1 Fix GitHub issue #356 - use pull strength for tri0/tri1 tie-offs.
When connecting module inout ports, an island is created. If there
is no other driver on one of the island ports, a tie-off is added.
In the case of a tri0 or tri1 net, this must have the correct (pull)
drive strength.

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!

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.

Martin Whitaker d6391490e3 Resize vector before assigning to a dynamic array word.
Failing to do this leads to an assertion failure in vvp.

Martin Whitaker c066e2d15c Properly implement casts from strings and dynamic arrays to vectors.
As discussed on iverilog-devel (2018-03-09), the existing implementation
(using Icarus-specific vpi functions) only worked with assignments to
simple variables, and could not be easily modified to work more generally.
So use the new vvp instructions added in the previous two commits.

Martin Whitaker ffb34861cf Fix GitHub issue #244: handle mixed signed/unsigned power operations.
The signed version of the power operation in vvp should only be used
if the exponent is signed. Both signed and unsigned versions will
produce the correct result regardless of the type of the base operand,
provided it has been appropriately extended to the result size.
