* defs.h (enum lval_type): New enumerator "lval_xcallable".
* extension-priv.h (struct extension_language_ops): Add the
xmethod interface.
* extension.c (new_xmethod_worker, clone_xmethod_worker,
get_matching_xmethod_workers, get_xmethod_argtypes,
invoke_xmethod, free_xmethod_worker,
free_xmethod_worker_vec): New functions.
* extension.h: #include "common/vec.h".
New function declarations.
(struct xmethod_worker): New struct.
(VEC (xmethod_worker_ptr)): New vector type.
(xmethod_worker_ptr): New typedef.
(xmethod_worker_vec): Likewise.
* gdbtypes.c (gdbtypes_post_init): Initialize "xmethod" field of
builtin_type.
* gdbtypes.h (enum type_code): New enumerator TYPE_CODE_XMETHOD.
(struct builtin_type): New field "xmethod".
* valarith.c (value_ptradd): Assert that the value argument is not
lval_xcallable.
* valops.c (value_must_coerce_to_target): Return 0 for
lval_xcallable values.
* value.c (struct value): New field XM_WORKER in the field
LOCATION.
(value_address, value_raw_address): Return 0 for lval_xcallable
values.
(set_value_address): Assert that the value is not an
lval_xcallable.
(value_free): Free the associated xmethod worker when freeing
lval_xcallable values.
(set_value_component_location): Assert that the WHOLE value is not
lval_xcallable.
(value_of_xmethod, call_xmethod): New functions.
