including the new U2F signatures.
Don't use sshsk_ecdsa_sign() directly, instead make it reachable via
sshkey_sign() like all other signature operations. This means that
we need to add a provider argument to sshkey_sign(), so most of this
change is mechanically adding that.

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.

Requires some caching of values, because the PAM code isn't
always called with packet context.

API, started almost exactly six years ago.
This change stops including the old packet_* API by default and makes
each file that requires the old API include it explicitly. We will
commit file-by-file refactoring to remove the old API in consistent
steps.

PubkeyAcceptedKeyTypes options. If only RSA-SHA2 siganture types were
specified, then authentication would always fail for RSA keys as the monitor
checks only the base key (not the signature algorithm) type against

Most people will 1) be using modern multi-factor authentication methods
like TOTP/OATH etc and 2) be getting support for multi-factor
authentication via PAM or BSD Auth.

Drop compatibility hacks for some ancient SSH
implementations, including ssh.com <=2.* and OpenSSH <= 3.*.
These versions were all released in or before 2001 and predate the
final SSH RFCs. The hacks in question aren't necessary for RFC-
compliant SSH implementations.

revert stricter key type / signature type checking in

refactor channels.c
Move static state to a "struct ssh_channels" that is allocated at
runtime and tracked as a member of struct ssh.
Explicitly pass "struct ssh" to all channels functions.
Replace use of the legacy packet APIs in channels.c.
Rework sshd_config PermitOpen handling: previously the configuration
parser would call directly into the channels layer. After the refactor
this is not possible, as the channels structures are allocated at
connection time and aren't available when the configuration is parsed.
The server config parser now tracks PermitOpen itself and explicitly
configures the channels code later.

Remove support for pre-authentication compression. Doing
compression early in the protocol probably seemed reasonable in the 1990s,
but today it's clearly a bad idea in terms of both cryptography (cf. multiple
compression oracle attacks in TLS) and attack surface.
Moreover, to support it across privilege-separation zlib needed
the assistance of a complex shared-memory manager that made the
required attack surface considerably larger.
Prompted by Guido Vranken pointing out a compiler-elided security
check in the shared memory manager found by Stack
(http://css.csail.mit.edu/stack/); ok deraadt@ markus@
NB. pre-auth authentication has been disabled by default in sshd
for >10 years.
