Shuffle the argument list for the synthesize method.
...
In preparation for using the synthesize method to replace the
elaborate_net method of PExpr, rework the interface to the
synthesize() method. This changes no fnctionality, but does set
up the infrastructure for the next step.

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.

Some synthesis errors were not incrementing the error count
...
This patch cleans up some of the crashes in the synthesis
code by incrementing the error count as appropriate. This
also removes the three false positives in the test suite
(Sorry-Ran-PASSED). A few other messages will change in
the test suite as well (blocksynth? and basiclatch).
