[channels.c]
Fix a trio of bugs in the local/remote window calculation for datagram
data channels (i.e. TunnelForward):
Calculate local_consumed correctly in channel_handle_wfd() by measuring
the delta to buffer_len(c->output) from when we start to when we finish.
The proximal problem here is that the output_filter we use in portable
modified the length of the dequeued datagram (to futz with the headers
for !OpenBSD).
In channel_output_poll(), don't enqueue datagrams that won't fit in the
peer's advertised packet size (highly unlikely to ever occur) or which
won't fit in the peer's remaining window (more likely).
In channel_input_data(), account for the 4-byte string header in
datagram packets that we accept from the peer and enqueue in c->output.

[ssh-keysign.c]
clean for -Wuninitialized (Id sync only; portable had this change)

Support CA keys in PKCS#11 tokens; feedback and ok markus@

[authfile.c]
commited the wrong version of the hostbased certificate diff; this
version replaces some strlc{py,at} verbosity with xasprintf() at
the request of markus@

[PROTOCOL.certkeys ssh-keygen.c]
tighten the rules for certificate encoding by requiring that options
appear in lexical order and make our ssh-keygen comply. ok markus@

[ssh.1 ssh_config.5 sshd.8]
Remove mentions of weird "addr/port" alternate address format for IPv6
addresses combinations. It hasn't worked for ages and we have supported
the more commen "[addr]:port" format for a long time. ok jmc@ markus@

[ssh.1]
Ciphers is documented in ssh_config(5) these days

[clientloop.c readconf.c readconf.h ssh.c ssh_config.5]
add a "ControlPersist" option that automatically starts a background
ssh(1) multiplex master when connecting. This connection can stay alive
indefinitely, or can be set to automatically close after a user-specified
duration of inactivity. bz#1330 - patch by dwmw2 AT infradead.org, but
further hacked on by wmertens AT cisco.com, apb AT cequrux.com,
martin-mindrot-bugzilla AT earth.li and myself; "looks ok" markus@

bz#1797: fix swapped args in upload_dir_internal(), breaking recursive
upload depth checks and causing verbose printing of transfers to always
be turned on; patch from imorgan AT nas.nasa.gov

[ssh-rsa.c]
more timing paranoia - compare all parts of the expected decrypted
data before returning. AFAIK not exploitable in the SSH protocol.

implement a timing_safe_cmp() function to compare memory without leaking
timing information by short-circuiting like memcmp() and use it for
some of the more sensitive comparisons (though nothing high-value was
readily attackable anyway); "looks ok" markus@

[ssh.c ssh_config.5]
expand %h to the hostname in ssh_config Hostname options. While this
sounds useless, it is actually handy for working with unqualified
hostnames:
Host *.*
Hostname %h
Host *
Hostname %h.example.org
