Here are various fixes:

- Patch 1: Better handling SKB extension allocation failures. A fix for
  v5.7.

- Patches 2, 3: Avoid resetting MPTCP limits when flushing MPTCP
  endpoints. With a validation in the selftests. Fixes for v5.7.

- Patches 4, 5, 6: Disallow '0' as ADD_ADDR retransmission timeout.
  With a preparation patch, and a validation in the selftests. Fixes for
  v5.11.

- Patches 8, 9: Fix C23 extension warnings in the selftests, spotted by
  GCC. Fixes for v6.16.
