djm@openbsd.org 7250879c72 upstream: include SHA2-variant RSA key algorithms in KEX proposal;
allows ssh-keyscan to harvest keys from servers that disable olde SHA1
ssh-rsa. bz#3029 from Jakub Jelen

deraadt@openbsd.org 4d28fa78ab upstream: When system calls indicate an error they return -1, not
some arbitrary value < 0.  errno is only updated in this case.  Change all
(most?) callers of syscalls to follow this better, and let's see if this
strictness helps us in the future.

Add monotime_ts and monotime_tv that return monotonic

timing with monotime_tv so that the callers will work over a clock step.

     [myproposal.h]
     trimm default proposals.

     This commit removes the weaker pre-SHA2 hashes, the broken ciphers
     (arcfour), and the broken modes (CBC) from the default configuration
     (the patch only changes the default, all the modes are still available
     for the config files).

     [myproposal.h]
     The current sharing of myproposal[] between both client and server code
     makes the previous diff highly unpallatable.  We want to go in that
     direction for the server, but not for the client.  Sigh.
