Shadow reduction part 3
...
Continue cleaning up shadowed variables, flagged by turning on -Wshadow.
No intended change in functionality. Patch looks right, and is tested
to compile and run on my machine. No regressions in test suite.

Pass file and line number information for expression constants.
...
This patch passes the file and line number information for
constants that are used in expressions.

Create a branch object to be the argument to the access function.
...
The NetBranch object is connected, but not like an object, so the
NetPins object base class is factored out from NetObj to handle the
connectivity, and the NetBranch class uses the NetPins to connect a
branch.
Also, account for the fact that nets with a discipline are by default
real-valued.

Detect and elaborate AMS access functions.
...
Detect function call expressions that turn out to be calls to the
access function of a nature. Elaborate the access function and stub
the emit code. This gets the access function just short of the code
generator.

A IVL_EX_CONCAT is always unsigned.
...
The signedness of an IVL_EX_CONCAT was not being set. This patch
forces it to always be unsigned as the standard specifies.

LineInfo uses perm_string for path.
...
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.
