[MPTCP][PATCH v6 mptcp-next 0/5] fullmesh path manager support

[Geliang Tang <geliangtang@gmail.com>]

From: Geliang Tang <geliangtang@xiaomi.com>

v6:
 - drop lookup_subflow_by_addrs()
 - pass three arrays instead of 'entries' in fill_local_adresses_vec()
 - drop the 'remote' argument of fill_local_addresses_vec
 - drop the 'local' argument of fill_remote_addresses_vec
 - fix the pm.subflows.
 - add limit testcase.

v5:
 - patch 1, add a new helper lookup_address_in_vec.
 - patch 2, update pm.subflows in the non-fullmesh case.
 - patch 4, add more tests.
 - tag: export/20210727T054640

v4:
 - add new helpers, fill_local/remote_addresses_vec
 - add max_subflows checks
 - add 'local' into the local addresses array only when no fullmesh
   entry found.
 - add signal,fullmesh check

v3:
 - the in-kernel fullmesh path manager has been dropped from this
   patchset, only keep the fullmesh flag support code.

v2:
 - Implement the fullmesh mode as an extension to the netlink PM, not a
   standalone PM as Paolo suggested.
 - drop duplicate code.
 - add a new per endpoint flag MPTCP_PM_ADDR_FLAG_FULLMESH.
