tc are used in some test scripts: mptcp_connect.sh, mptcp_join.sh and simult_flows.sh. It makes sense to check if tc is installed before running these scripts, just like other tools. So this patch add 'tc' check for mptcp_lib_check_tools(), and check it in these test scripts.

This patch exports ip_mptcp into mptcp_lib.sh as a public variable, named MPTCP_LIB_IP_MPTCP. Add a helper mptcp_lib_set_ip_mptcp() to set it, and a helper mptcp_lib_is_ip_mptcp() to test whether it is set. Use these two helpers in mptcp_join.sh.

This patch is prepared for coming commits.

From: Geliang Tang tanggeliang@kylinos.cn

The output formats of 'ip mptcp' commands are much different from that of 'pm_nl_ctl' commands.

This patch adds a new helper format_endpoints() to format the outputs of 'ip mptcp' and 'pm_nl_ctl' with 'endpoints' arguments to hide these differences.

A new helper named get_endpoint() has also been added to show a specific endpoint identified by the given address ID, similar to mptcp_join.sh's pm_nl_show_endpoints() helper, but showing all entries.

Use these two helpers in mptcp_join.sh and pm_netlink.sh to replace all 'pm_nl_ctl get' commands and outputs of 'pm_nl_ctl dump/get'.

This patch uses 'case' statements to simplify pm_nl_add_endpoint() and pm_nl_check_endpoint(). And simplify pm_nl_check_endpoint() with check_output() helper. Also update pm_nl_del_endpoint() to avoid the 'double quote' shellcheck warning.

pm_nl_set_endpoint()

From: Geliang Tang tanggeliang@kylinos.cn

Use those newly added pm_nl endpoint ops helpers to replace all 'pm_nl_ctl' commands with 'limits', 'add', 'del', 'flush', 'show' and 'set' arguments in scripts mptcp_sockopt.sh and simult_flows.sh.

In pm_netlink.sh, add wrappers of there helpers to make the function names shorter. Then use the wrappers to replace all 'pm_nl_ctl' commands.
