We already limited pending_ann_map and early_ann_map to 10,000 entries: do the same for pending_nannounces, pending_cupdates and early_cupdates. Add CI_UNEXPECTED so CI gets upset if this happens unexpectedly. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Decryption is pretty efficient, but incoming traffic can bog down connectd, especially on smaller nodes, so simply limit it to 1MB per second. This triggers in various tests, which is good: shows that it's working, and that we continue to (slowly!) process traffic.
