Cary R ddaba5b017 Print a better error message for the optional system tasks/funcs
This patch adds better error messages (compiletf) for the optional
system tasks and functions (Annex C 1364-2005). Doing this also
makes calling them fail more gracefully (it is no longer a RE).

Cary R af08ff64c7 Add message the the $dumpports* task are not available
These are in the standard and we did not have error messages
for them. This patch make calling these tasks a compiletf
fatal error.

Cary R 036c176e8b Add the $fread() system function.
This patch adds the $fread() system function. Icarus does not
currently allow missing arguments in functions so the following
standard specified functionality is not supported:

  res = $fread(mem, fd,,count);

It also fixes a memory leak in fopen related to the get_filename
refactoring I recently did.

Cary R 92dd13a225 Error message for missing system tasks/functions.
This patch adds an error message for the standard system
tasks and functions that are not currently implemented.
These are currently $fmonitor*, $ferror, $fread, the
queue and PLA tasks.

Cary R 7c152685dc Clean up more compiletf routines, etc.
This patch cleans up some of the code to use common compiletf
routines where appropriate. It also adds code to print the
number of extra arguments and cleans up the messages a bit.

Cary R 4010f6e710 Add $simparam and other fixes.
This patch adds $simparam and $simparam$str from Verilog-A.
The analog simulator parameters return 0.0 or N/A. The
vvp_cpu_wordsize system function has been moved into the
$simparam call and is now named CPUWordSize.

This patch also starts the factoring of common code in the
vpi directory. Some routines were renamed.

The priv.c file was renamed to sys_priv.c to match the
include file.

System functions can now have strings put to their output.

Cary R 608c2574bd Add $finish_and_return.
This new system task can be used to set the vvp return value
and finish the simulation.

Cary R 3a8a6976e1 Add $vvp_cpu_wordsize function
This patch adds a new system function $vvp_cpu_wordsize. It returns
the size of the underlying CPU word (long) in bits. This function
can be used to write fully portable tests for the test suite. Other
functions will be added as needed.
