rS329743: Allow route change requests to not specify the gateway.

Summary

Only require a gateway to be specified on a route add request. On
a route change request that does not specify the gateway, the
gateway will remain the same. This allows changing other route
parameters without having to re-specifying the gateway, like in
"route change 10.0.0.0/8 -mtu 9000".

Do you really need to mix whitespace change with the fix (last chunk)?

This is missing the associated man page change that changes gateway to [gateway] on the change syntax,
Though perhaps BSD did allow this in the past, the man page never said that the gateway was optional as far as I can recall.

I agree with the change as well; the regression seems to have happened when the code was refactored and the "add" and "change" code became joined.

How it supposed to work for RADIX_MPATH case? I know RADIX_MPATH is currently broken, but anyway...

Fix the manpage to document that the gateway parameter is
optional for most route subcommands.

sbin/route/route.8
136	BTW, this is wrong. The syntax implies that "flush" is an argument accepted by the -n flag (you can check out "man route" to see how this is rendered and that it is clearly wrong). I have opened a separate review that fixes this: https://reviews.freebsd.org/D14401

sbin/route/route.8
136	The whole man page could use some reworking. Including expanding out the various correct forms in the SYNOPSIS section and removing the scattering of syntax info. Has anyone run this page through, um, igor from ports?

sbin/route/route.8
136	I did run it through igor. It complains about "aggregatable", believing that it's not a real word (Google seems to disagree). Other than that the file is clean.
