Stephen Williams 68cf5baba5 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.

Stephen Williams 148e6768f6 Clean up modpath vpi interface 
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.

Cary R 3258b7726b Pass local scope precision from compiler to vvp/etc. 
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.

yang yun ju 9d39b3a514 Access to modpaths via VPI 
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.

Cary R 15058a31b9 vpiFullName for real variables will now return the correct value. 
This patch makes vpiFullName for real variables return the correct
value. A Scope reference was added to the base structure along with
the relevant code to support generating the full name. A couple of
memory leaks were plugged and some formatting fixed as well.

steve 91d84e7dc7 Major rework of array handling. Memories are replaced with the 
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.
