[PATCH net-next 0/8] mptcp: small improvements, fix and clean-ups

This series contain mostly unrelated patches:

- The two first patches can be seen as "fixes". They are part of this
series for -next because it looks like the last batch of fixes for
v6.9 has already been sent. These fixes are not urgent, so they can
wait if an unlikely v6.9-rc8 is published. About the two patches:
- Patch 1 fixes getsockopt(SO_KEEPALIVE) support on MPTCP sockets
- Patch 2 makes sure the full TCP keep-alive feature is supported,
not just SO_KEEPALIVE.

- Patch 3 is a small optimisation when getsockopt(MPTCP_INFO) is used
without buffer, just to check if MPTCP is still being used: no
fallback to TCP.

- Patch 4 adds net.mptcp.available_schedulers sysctl knob to list packet
schedulers, similar to net.ipv4.tcp_available_congestion_control.

- Patch 5 and 6 fix CheckPatch warnings: "prefer strscpy over strcpy"
and "else is not generally useful after a break or return".

- Patch 7 and 8 remove and add header includes to avoid unused ones, and
add missing ones to be self-contained.
