so they are useful as comments without extra shell redirection and so they
don't clutter actual errors on stderr.
Add a -q flag to shut them up.

The sanitise_stdfd call makes sure that standard file descriptors are
open (if they were closed, they are connected with /dev/null).
Do not close stdin in any case to prevent error messages when stdin is
read multiple times and to prevent later usage of fd 0 for connections,
e.g.
echo localhost | ssh-keyscan -f - -f -
While at it, make stdin-related error messages nicer.

userspace: remove vestigial '?' cases from top-level getopt(3) loops
getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument. We can
handle this case with the "default" failure case with no loss of
legibility. Hence, remove all the redundant "case '?':" lines.

pfd[].revents is not cleared. There are subtle errors in various programs.
In this particular case, the program should error out. ok djm millert

appropriate. Saves 1k of static storage and prevents snprintf "possible
truncation" warnings from newer compilers (although in this case it's false
positive since the actual sizes are limited by the output size of the SHA1).

exchange method based on Streamlined NTRU Prime (coupled with X25519).
The previous sntrup4591761x25519-sha512@tinyssh.org method is
replaced with sntrup761x25519-sha512@openssh.com. Per the authors,
sntrup4591761 was replaced almost two years ago by sntrup761.
The sntrup761 implementaion, like sntrup4591761 before it, is public
domain code extracted from the SUPERCOP cryptography benchmark
suite (https://bench.cr.yp.to/supercop.html).
Thanks for Daniel J Bernstein for guidance on algorithm selection.

Add monotime_ts and monotime_tv that return monotonic
timespec and timeval respectively. Replace calls to gettimeofday() in packet
timing with monotime_tv so that the callers will work over a clock step.
Should prevent integer overflow during clock steps reported by wangle6 at
