gfortran.h (gfc_get_namespace): Add second argument to prototype.

fortran/
* gfortran.h (gfc_get_namespace): Add second argument to prototype.
* intrinsic.c (gfc_intrinsic_init_1): Pass second argument to
gfc_get_namespace.
* module.c (mio_namespace_ref, load_needed): Likewise.
* parse.c (parse_interface, parse_contained): Likewise.  Here the
correct second argument matters.
* symbol.c (gfc_get_namespace): Add parent_types argument, only copy
parent's implicit types if this is set.
(gfc_symbol_init_2): Pass second argument to gfc_get_namespace.
* trans-common.c (build_common_decl): Likewise.

testsuite/
* gfortran.dg/implicit_3.f90: New test.
