Subject: [PATCH net-next v2 14/15] selftests: mptcp: add
 mptcp_lib_check_transfer

From: Geliang Tang <geliang.tang@...e.com>

To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.

check_transfer() and print_file_err() helpers are defined both in
mptcp_connect.sh and mptcp_sockopt.sh, export them into mptcp_lib.sh
and rename them with mptcp_lib_ prefix. And use them in all scripts.

Note: In mptcp_sockopt.sh it is OK to drop 'ret=1' in check_transfer()
because it will be set in run_tests() anyway.
