[RFC] lib/mi-support.exp: kill SID inferior prior to reconnecting

[Kevin Buettner <kevinb@redhat.com>]

Below is another SID related patch.   This patch was motivated by
gdb.mi/mi-var-cp.exp which uses the inline test support in
lib/mi-support.exp.   The first inline test runs okay, but subsequent
tests run into trouble when attempting to reconnect to SID using the
same port as the existing connection.  This patch simply kills (or
attempts to kill) the inferior first to avoid that problem.

Comments?

	* lib/mi-support.exp (mi_gdb_target_load): Do a "kill" prior
	to restarting SID.
