[PATCH 11/16] move some statics from remote_read_qxfer into struct remote_state

[Tom Tromey <tromey@redhat.com>]

This moves a few static variables out of remote_read_qxfer and into
remote_state.  It is unclear to me if this data can ever be required
to be kept around across a potential target switch, but it is
definitely safe to move it into the remote state object.

	* remote.c (struct remote_state) <finished_object,
	finished_annex, finished_offset>: New fields.
	(remote_read_qxfer): Use remote_state fields; remove static
	variables.
