selftests/bpf: Test bpf_skb_adjust_room on CHECKSUM_PARTIAL
When the bpf_skb_adjust_room() shrinks the skb such that its csum_start is invalid, the skb->ip_summed should be reset from CHECKSUM_PARTIAL to CHECKSUM_NONE.
The commit 54c3f1a81421 ("bpf: pull before calling skb_postpull_rcsum()") fixed it.
This patch adds a test to ensure the skb->ip_summed changed from CHECKSUM_PARTIAL to CHECKSUM_NONE after bpf_skb_adjust_room().

selftest/bpf: Add test for bpf_getsockopt()
This patch removes the __bpf_getsockopt() which directly reads the sk by using PTR_TO_BTF_ID. Instead, the test now directly uses the kernel bpf helper bpf_getsockopt() which supports all the required optname now.
TCP_SAVE[D]_SYN and TCP_MAXSEG are not tested in a loop for all the hooks and sock_ops's cb. TCP_SAVE[D]_SYN only works in passive connection. TCP_MAXSEG only works when it is setsockopt before the connection is established and the getsockopt return value can only be tested after the connection is established.

af_unix: Remove UNIX_ABSTRACT() macro and test sun_path[0] instead.
In BSD and abstract address cases, we store sockets in the hash table with keys between 0 and UNIX_HASH_SIZE - 1. However, the hash saved in a socket varies depending on its address type; sockets with BSD addresses always have UNIX_HASH_SIZE in their unix_sk(sk)->addr->hash.
This is just for the UNIX_ABSTRACT() macro used to check the address type. The difference of the saved hashes comes from the first byte of the address in the first place. So, we can test it directly.
Then we can keep a real hash in each socket and replace unix_table_lock with per-hash locks in the later patch.

bpf: selftest: Test batching and bpf_(get|set)sockopt in bpf tcp iter
This patch adds tests for the batching and bpf_(get|set)sockopt in bpf tcp iter.
It first creates: a) 1 non SO_REUSEPORT listener in lhash2. b) 256 passive and active fds connected to the listener in (a). c) 256 SO_REUSEPORT listeners in one of the lhash2 bucket.
The test sets all listeners and connections to bpf_cubic before running the bpf iter.
The bpf iter then calls setsockopt(TCP_CONGESTION) to switch each listener and connection from bpf_cubic to bpf_dctcp.
The bpf iter has a random_retry mode such that it can return EAGAIN to the usespace in the middle of a batch.
