[PATCH 2/7] Move rs->support_vCont_t to a separate struct

[Yao Qi <yao@codesourcery.com>]

This is a refactor patch to move field 'support_vCont_t' to a separate
struct 'support_v_cont', to prepare for adding more fields in it in
the next patch.

2013-03-11  Yao Qi  <yao@codesourcery.com>

	* remote.c (struct support_v_cont): New.
	(struct remote_state) <support_vCont_t>: Remove.
	<support_vCont>: New field.
	(remote_vcont_probe, remote_stop_ns): Update.
