percent_expansions more consistent. - %C is moved into its own function and added to Match Exec. - move the common (global) options into a macro. This is ugly but it's the least-ugly way I could come up with. - move IdentityAgent and ForwardAgent percent expansion to before the config dump to make it regression-testable. - document all of the above ok jmc@ for man page bits, "makes things less terrible" djm@ for the rest.

signature work - returns ability to add/remove/specify algorithms by wildcard.

2018-07-03upstream: Improve strictness and control over RSA-SHA2 signaturedjm@openbsd.org
In ssh, when an agent fails to return a RSA-SHA2 signature when requested and falls back to RSA-SHA1 instead, retry the signature to ensure that the public key algorithm sent in the SSH_MSG_USERAUTH matches the one in the signature itself. In sshd, strictly enforce that the public key algorithm sent in the SSH_MSG_USERAUTH message matches what appears in the signature. Make the sshd_config PubkeyAcceptedKeyTypes and HostbasedAcceptedKeyTypes options control accepted signature algorithms (previously they selected supported key types). This allows these options to ban RSA-SHA1 in favour of RSA-SHA2. Add new signature algorithms "rsa-sha2-256-cert-v01@openssh.com" and "rsa-sha2-512-cert-v01@openssh.com" to force use of RSA-SHA2 signatures with certificate keys. feedback and ok markus@ OpenBSD-Commit-ID: c6e9f6d45eed8962ad502d315d7eaef32c419dde
