    fortran: enable ptype/whatis for modules.

    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.
        * symtab.h: New domain for fortran modules.

    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.

    fortran: enable ptype/whatis for user defined types.

        (gdb) ptype type
        old> No symbol "type" in current context.
        new> type = Type type
             integer(kind=4) :: t_i
             End Type type

        * f-exp.y (yylex): Add domain array to enable lookup
        in multiple domains. Loop over lookup domains and try
        to find requested symbol. Add STRUCT_DOMAIN to lookup
        domains to be able to query for user defined types.

    testsuite/
        * gdb.fortran/type.f90: New file.
        * gdb.fortran/whatis_type.f90: New file.
