replace deprecated yacc directives
...
bison 3.4.2 complains when encountering '%pure-parser':
"warning: deprecated directive, use ‘%define api.pure’"
A quick google suggests this option has been around since at least
2012, maybe longer, so probably safe to replace.

Correctly handle explicit and wildcard package imports.
...
Explicit imports should always conflict with local declarations using
the same name. Wildcard imports only conflict if they are referenced
before a local declaration with the same name.
This also unifies the detection of identifier conflicts.

With '-i', don't return an error when there are no top-level modules.
...
The '-i' option is there to allow the compiler to be used to check an
incomplete design for errors. With no top-level modules, nothing will
be elaborated, but at least will be checked for syntax errors.

Improve handling of invalid packed and unpacked dimensions.
...
As reported on iverilog-devel on 2018-10-12, a dimension size of zero
could case the compiler to go into an infinite loop. Further tests
showed that unsized or queue dimensions entered as packed dimensions
would cause the compiler to crash.

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.

Schedule UDP initial 0/1 assignments to occur during time 0.
...
This allows any always processes that are sensitive to the UDP output
to start first. This fixes a time 0 race that was found in a Lattice
Semiconductor simulation library (reported on iverilog-devel).
If the initial value is 'x', propagate the value to the UDP output
before the start of simulation, to avoid unwanted update events on
the z -> x transition on downstream nets.
