Parse contribution statements as far as pform.
...
Contribution statements have an l-value and r-value. Parse those
expressions into pform so that elaboration has something to work with.
In this process, this patch also changes the PECallFunction class to
use the vector template instead of the svector template. The latter
doesn't add anything over the STL vector template, so this is a start
of working the svector out.

Move implicit net creation from elaboration to elaborate_sig
...
If implicit nets are declared during elaboration, then the success
of binding during elaboration will depend on the order of the code
in the source file.

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.

take over those functions in the netlist.
