signature work - returns ability to add/remove/specify algorithms by
wildcard.
Algorithm lists are now fully expanded when the server/client configs
are finalised, so errors are reported early and the config dumps
(e.g. "ssh -G ...") now list the actual algorithms selected.
Clarify that, while wildcards are accepted in algorithm lists, they
aren't full pattern-lists that support negation.

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.

when choosing a prime. An extra increment of linenum snuck in as part of the
conversion to getline(). OK djm@ markus@

Add getline for the benefit of platforms that don't have it. Sourced
from NetBSD (OpenBSD's implementation is a little too chummy with the
internals of FILE).
e.g.
PermitListen 2222 8080
is equivalent to:
PermitListen *:2222 *:8080

Since autoconf always uses $CC to link C programs, allowing users to
override LD caused mismatches between what LD_LINK_IFELSE thought worked
and what ld thought worked. If you do need to do this kind of thing you
need to set a compiler flag such as gcc's -fuse-ld in LDFLAGS.
authorized_keys lines that contained permitopen/permitlisten were being
treated as invalid.

addresses may be listened on when the client requests remote forwarding (ssh
-R).
This is the converse of the existing PermitOpen directive and this
includes some refactoring to share much of its implementation.
