upstream commit

Make ssh_packet_set_rekey_limits take u32 for the number of
seconds until rekeying (negative values are rejected at config parse time).
This allows the removal of some casts and a signed vs unsigned comparison
warning.

rekey_time is cast to int64 for the comparison which is a no-op
on OpenBSD, but should also do the right thing in -portable on
anything still using 32bit time_t (until the system time actually
wraps, anyway).

some early guidance deraadt@, ok djm@
