Fix for br932 part 2 - make $fopen accept SV 'string' type.

The is_string_obj function in vpi/sys_priv.c needed to be updated to
recognise the vpiStringVar object type.

Elaborate VHDL entity port types/expressions.
...
We need to elaborate expressions so that function calls in
expressions (i.e. ranges) get bound to their proper scope.
This binding is in turn used to emit package scopes. This
is particularly interesting for ports of entities.

Fix repeated use of disabled const functions.
...
If constant functions are exited by a return/disable, fix
the leaked "disable" flag that causes blocks in the next
try at the function to not work.
There are also a lot of debug messages added to help find
this and similar problems.

Use $ivl_unsigned to implement VHDL to_unsigned function.
...
The VHDL to_unsigned function with to arguments is best handled
in the ivl elaborator, so have it generate an $ivlh_to_unsigned
function call in the vhdlpp code, and implement it in the ivl
core.
Also, implement the 'length attribute as a $bits() call for
similar reasons.

Rework scope types and constants so we can tell imported from local names.
...
The package emit of types and constants needs to know which names are
from the current type and which are imported from libraries. Rework
the scope handling of those names so that the information is preserved.

Revised fix for bug 931.
...
We can't directly determine that a %fork operation is a task or function
call, so need to infer this by comparing the parent and child scopes.

Fix for br931.
...
Task and function calls are handled in vvp using the fork/join
instructions. The join instruction after a call must reap the
task/function thread.

Handle out-of range and undefined LHS bit/part selects in assignments.

For constant bit/part selects, issue a warning if the select is out
of range or an undefined value. In any case, the RHS value should be
discarded, and the actual assignment should be skipped.

Fix vvp memory leak for VPI call with no calltf.
...
If a VPI call with real arguments has no calltf function, we still
need to pop the arguments off the vthread stack. Similarly, if it
has a real result, we need to push a value onto the vthread stack.

Added thread stack memory leak check to vvp.

When a vvp thread terminates, its real and string stacks should be empty.
Adding assertions to this effect catches some code generator bugs.

Implement class constructors.
...
Class constructors are the "new" method in a class description.
Elaborate the constructor as an ordinary method, but the only
way to access this method is to implicitly call it. The elaborator
will take the constructor call and generate a naked "new" expression
and implicit constructor method call with the object itself as the
return value.
