  expr: Refactor parsing of assignments and exchanges.

As written, it was difficult for the OVN logical action code to add support
for new actions of the form "dst = ...", because the code to parse the left
side of the assignment was a monolithic part of the expr library.  This
commit refactors the code division so that an upcoming patch can support a
new "dst = func(args);" kind of action.
