convert to_get_unwinder and to_get_tailcall_unwinder to methods
This converts to_get_unwinder and to_get_tailcall_unwinder to methods
and arranges for them to use the new delegation scheme.
This just lets us avoid having a differing style (neither new-style
nor INHERIT) of delegation in the tree.

* target.c (target_get_unwinder): Rewrite.
(target_get_tailcall_unwinder): Rewrite.
* record-btrace.c (record_btrace_to_get_unwinder): New function.
(record_btrace_to_get_tailcall_unwinder): New function.
(init_record_btrace_ops): Update.
* target.h (struct target_ops) <to_get_unwinder,
to_get_tailcall_unwinder>: Now function pointers. Use
TARGET_DEFAULT_RETURN.
