Clean up rather poorly written modpath vpi support, fixing the
parse of the modpath syntax element to not use pointless globals.
Collect the modpath code into the delay.cc file instead of the
inapropriate vpi_signal.cc source file.

Add support for accessing the modpath nodes via PLI,
and add support for the vpi_set_delays and vpi_put_delays
functions to set the delays on those paths.

Modified the code that deals with real variables to accept an integer
value when using vpi_put_value(). Also added some type of diagnostic
message for all switch defaults that have an assert(0) to indicate an
error condition, removed CVS comments and removed a small section of
unreachable code.
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.
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.

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.
Words of net arrays were incorrectly added to the scope. They should
only be attached to the array, and accessed as a word of the array.

more general concept of arrays. The NetMemory and NetEMemory
classes are removed from the ivl core program, and the IVL_LPM_RAM
lpm type is removed from the ivl_target API.
2) adds acc_compare_handle, acc_fetch_range, acc_next_scope and
tf_isetrealdelay, acc_handle_scope
3) makes acc_next reentrant
4) adds basic vpiWire type support
5) fills in some acc_object_of_type() and acc_fetch_{full}type()
6) add vpiLeftRange/RigthRange to signals
length checks for *_get_str() buffers,
temporary buffers for *_get_str() data,
dynamic storage for vpi_get_data() in memory types
shared with signal white space
