hm, I haven't been able to reproduce the hang you have experienced when
setting
rekeylimit low. Even setting RekeyLimit=16 produces a working session for me.

This isn't to say that we shouldn't set a minimum.

Created an attachment (id=1015)
 --> (http://bugzilla.mindrot.org/attachment.cgi?id=1015&action=view)
Minimum 1k rekeylimit, check for integer wrap

This checks that the RekeyLimit is >= 1024 and raises a fatal() error if it
isn't. 

It also checks for integer wraparound (because rekey_limit is only a signed
int) and fatal()s if it wraps.
