Out path term for modpaths
...
Add vvp support for modpath path term outputs. This also introduces
the concept of path terms and moves towards the path term in general
for getting at the endpoits of a modpath.

...
This patch adds ivl_scope_time_precision() to the compiler which can
be used to extract the local scope precision. tgt-stub and tgt-vvp
have been modified to use this new function and output a value that
is appropriate. The vvp runtime has been altered to use this new
data which is accessed with the vpip_time_precision_from_handle()
function. vpiTimePrecision uses this function to return the correct
precision.

Implement the swrite* and sformat system tasks plus a few other fixes.
...
This patch implements the swrite* and sformat system tasks. It also
makes $simtime distinguishable from the other integer time tasks.
This was needed to get the correct time units when $simtime was given
as an argument to $swrite*. The string constant code was also modified
to allow a string to be returned as a vector (0/1 bit pattern).
Here are some more specifics about the swrite* changes.
1. They do not share formatting code with the other display functions,
so they may/will produce different results.
2. All %{alpha} codes allow a width and justification. Others have been
enhanced (%t allows the default width and precision to be overridden,
time functions print with time formatting, better error checking and
messages, etc.).
3. %u and %z formatting codes have been added. It is important to note
that these two formats can produce embedded NULLs, since these
functions are returning a string anything after the first NULL will
not be reachable! memcpy is used instead of regular string processing
where needed so that the original string will contain the total
result. The size returned when the string is created is the true
length. A warning will be printed if a string with embedded NULLs is
produced (strlen() does not match the true length).
4. Real numbers are printed with %g instead of %f.
Once this new formatting code has been evaluated we should incorporate
the changes/fixes into the formatting code for the other functions or
the other functions could be modified to use this new code. The true
string length is available so we should be able to work around the
embedded NULL problem.

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.

routines that check for this can now be simplified since this (string
