Logging UDP and TCP connection attempts should not be enabled by default.
...
It's trivial to create a denial of service attack on a box so enabled.
These messages, if enabled at all, must be rate-limited. (!)

Uniformized pr_ctlinput protosw functions. The third arg is now `void
...
*' instead of caddr_t and it isn't optional (it never was). Most of the
netipx (and netns) pr_ctlinput functions abuse the second arg instead of
using the third arg but fixing this is beyond the scope of this round
of changes.

Changed in_pcblookuphash() to not automatically call in_pcblookup() if

the lookup fails. Updated callers to deal with this. Call in_pcblookuphash
instead of in_pcblookup() in in_pcbconnect; this improves performance of
UDP output by about 17% in the standard case.
