Add vpiType to the vpi_get_str() function.
...
vpi_get_str() can now return a reasonable value for most of the
types used in vvp. I'm not certain I got all of them, but they
are easy to add if any are missing. I also fixed a couple of
typos that I found while looking for all the different types.

Fix return of net strength value.
...
The calculated return value for the calculated strength value of
a net was left dangling. This patch fixes that. See pr1770199 in
the regression test suite.

Check the random function seed type and a fix to handle time variables.
...
The standard states that the seed for the random functions should be
an integer/time variable or a register. This patch fixes the compiletf
routines to check for this. There is also a small patch to
vvp/vpi_signal.cc that removes an assert that was failing and replaces
it with appropriate code. The assert was verifying that the source was
not bigger than an integer. The problem with this is that a time
variable or register may be bigger than an integer. I altered the code
to remove the assert and copy only the lower (8 * sizeof integer) bits.
The potential overflow/loss of precision is not checked. This passes
the regression tests.

more general concept of arrays. The NetMemory and NetEMemory
