Added new domain MODULE_DOMAIN for fortran modules to avoid
issues with sharing namespaces (e.g. when a variable currently
in scope has the same name as a module).
(gdb) ptype modname
old> No symbol "modname" in current context.
new> type = module modname
This fixes PR 15209 and also addresses the issue
with sharing namespaces:

* cp-namespace.c (cp_lookup_nested_symbol): Enable
nested lookups for fortran modules.
* dwarf2read.c (read_module): Add fortran module to
the symbol table.
(add_partial_symbol, add_partial_module): Add fortran
module to the partial symbol table.
(new_symbol_full): Create full symbol for fortran module.
* f-exp.y (yylex): Add new module domain to be parsed.

testsuite/
* gdb.fortran/module.exp: Completion matches fortran module
names as well. ptype/whatis on modules return a proper type.
Add new check for having the correct scope.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
