This patch added the remove addr and subflow test cases and two new
functions.

The first function run_remove_tests calls do_transfer with two new
arguments, rm_nr_ns1 and rm_nr_ns2, for the numbers of addresses should be
removed during the transfer process in namespace 1 and namespace 2.

If both these two arguments are 0, we do the join test cases with
"mptcp_connect -j" command. Otherwise, do the remove test cases with
"mptcp_connect -r" command.

The second function chk_rm_nr checks the RM_ADDR related mibs's counters.

The output of the test cases looks like this:

11 remove single subflow syn[ ok ] - synack[ ok ] - ack[ ok ]
rm [ ok ] - sf [ ok ]
12 remove multiple subflows syn[ ok ] - synack[ ok ] - ack[ ok ]
rm [ ok ] - sf [ ok ]
13 remove single address syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
rm [ ok ] - sf [ ok ]
14 remove subflow and signal syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
rm [ ok ] - sf [ ok ]
15 remove subflows and signal syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
rm [ ok ] - sf [ ok ]
