Make the go32-nat.c target inherit inf-child.c.
So that all native targets inherit a single "superclass".
Target methods that are set to or do the same as inf-child.c's are
removed.
Tested by cross building on Fedora 17.

2014-03-07 Pedro Alves <palves@redhat.com>
* go32-nat.c: Include inf-child.h.
(go32_ops): Delete global.
(go32_close, go32_detach, go32_prepare_to_store, go32_can_run):
Delete methods.
(go32_create_inferior): Push the passed in target pointer instead
of referencing go32_ops.
(init_go32_ops): Delete function. Moved parts to _initialize_go32_nat.
(go32_target): New function, based on init_go32_ops, but inherit
inf_child_target.
(_initialize_go32_nat): Use go32_target. Move parts of
init_go32_ops here.
