This patch adds a new helper get_info_value(), using 'sed' command to
parse the value of the given item name in the line with the given keyword,
to make chk_mptcp_info() and pedit_action_pkts() more readable.
Also add another helper evts_get_info() to use get_info_value() to parse
the output of 'pm_nl_ctl events' command, to make all the userpsace pm
selftests more readable, both in mptcp_join.sh and userspace_pm.sh.

To: mptcp; +Cc: Geliang Tang
This patch adds a new argument namespace to userspace_pm_add_addr() and
userspace_pm_add_sf() to make these two helper more versatile.
Add two more versatile helpers for userspace pm remove subflow or address:
userspace_pm_rm_addr() and userspace_pm_rm_sf(). The original test helpers
userspace_pm_rm_sf_addr_ns1() and userspace_pm_rm_sf_addr_ns2() can be
replaced by these new helpers.

This patch adds a selftest for userpsace PM to remove id 0 subflow. Use
userspace_pm_add_sf() to add a subflow, and pass initial ip address to
userspace_pm_rm_sf() to remove id 0 subflow.
Add a new helper chk_all_subflows(), in it use 'ss' command
ss -ti | grep -c tcp-ulp-mptcp
to get the "correct" amount of subflows, including the initial
subflow.
When closing the initial subflow in __mptcp_close_ssk(), dispose_it is
false, then tcp_disconnect is invoked. This will send a MP_RST to close
a subflow on the peer too. So chk_rst_nr() is added in this test, and
chk_all_subflows after closing the initial subflow is '1 1', not '2 1'.

This patch drops id 0 limitation in mptcp_nl_cmd_sf_create() to allow
creating additional subflows with the local addr ID 0.
There is no reason not to allow additional subflows from this local
address: we should be able to create new subflows from the initial
endpoint. This limitation was breaking fullmesh support from userspace.
Fixes: 702c2f646d42 ("mptcp: netlink: allow userspace-driven subflow establishment")
Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/391

This patch adds a selftest to create id 0 subflow. Pass id 0 to the
helper userspace_pm_add_sf() to create id 0 subflow. chk_mptcp_info
shows one subflow but chk_all_subflows shows two subflows in each
namespace.

This patch adds the ability to send RM_ADDR for local ID 0. Check
whether id 0 address is removed, if not, put id 0 into a removing
list, pass it to mptcp_pm_remove_addr() to remove id 0 address.
There is no reason not to allow the userspace to remove the initial
address (ID 0). This special case was not taken into account not
letting the userspace to delete all addresses as announced.
