libpq: Trace frontend authentication challenges
If tracing was enabled during connection startup, these messages would
previously be listed in the trace output as something like this:
F 54 Unknown message: 70
mismatched message length: consumed 4, expected 54
With this commit their type and contents are now correctly listed:
F 36 StartupMessage 3 0 "user" "foo" "database" "alvherre"
F 54 SASLInitialResponse "SCRAM-SHA-256" 32 'n,,n=,r=nq5zEPR/VREHEpOAZzH8Rujm'
F 108 SASLResponse
'c=biws,r=nq5zEPR/VREHEpOAZzH8RujmVtWZDQ8glcrvy9OMNw7ZqFUn,p=BBwAKe0WjSvigB6RsmmArAC+hwucLeuwJrR5C/HQD5M='
