I've adressed John's nit in patch 3, and added the reviews and acks.

Changes since v3:
- Clarify !psock check in sock_map_link_no_progs

Changes since v2:
- Remove sk_psock_hooks based on Jakub's idea
- Fix reference to tcp_bpf_clone in commit message
- Add inet_csk_has_ulp helper

Changes since v1:
- Check newsk->sk_prot in tcp_bpf_clone
- Fix compilation with BPF_STREAM_PARSER disabled
- Use spin_lock_init instead of static initializer
- Elaborate on TCPF_SYN_RECV
- Cosmetic changes to TEST macros, and more tests
- Add Jakub and me as maintainers
