add Cisco to the list of clients that choke on the
hostkeys update extension. Pointed out by Howard Kash

Add "PuTTY_Local:" to the clients to which we do not
offer DH-GEX. This was the string that was used for development versions
prior to September 2014 and they don't do RFC4419 DH-GEX, but unfortunately
there are some extant products based on those versions. bx2424 from Jay
Rouman, ok markus@ djm@

Cap DH-GEX group size at 4kbits for Cisco implementations.
Some of them will choke when asked for preferred sizes >4k instead of
returning the 4k group that they do have. bz#2209, ok djm@

Remove pattern length argument from match_pattern_list(), we
only ever use it for strlen(pattern).
Prompted by hanno AT hboeck.de pointing an out-of-bound read
error caused by an incorrect pattern length found using AFL
and his own tools.

Blacklist DH-GEX for specific PuTTY versions known to
send non-RFC4419 DH-GEX messages rather than all versions of PuTTY.
According to Simon Tatham, 0.65 and newer versions will send RFC4419 DH-GEX
messages. ok djm@
Don't send hostkey advertisments
(hostkeys-00@openssh.com) to current versions of Tera Term as they can't
handle them. Newer versions should be OK. Patch from Bryan Drewery and

OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of connections
using the curve25519-sha256@libssh.org KEX exchange method to fail
when connecting with something that implements the spec properly.
Disable this KEX method when speaking to one of the affected
versions.

refuse RSA keys from old proprietary clients/servers that use the
obsolete RSA+MD5 signature scheme. it will still be possible to connect
with these clients/servers but only DSA keys will be accepted, and we'll
deprecate them entirely in a future release. ok markus@

Send client banner immediately, rather than waiting for the server to
move first for SSH protocol 2 connections (the default). Patch based on

[mux.c readconf.h channels.h compat.h compat.c ssh.c readconf.c channels.c version.h]
unbreak remote portforwarding with dynamic allocated listen ports:
1) send the actual listen port in the open message (instead of 0).
this allows multiple forwardings with a dynamic listen port
2) update the matching permit-open entry, so we can identify where
to connect to

bz #1019: some ssh.com versions apparently can't cope with the

Patch originally by Dan Astorian, but worked on by several people
Adds GatewayPorts=clientspecified option on server to allow remote
forwards to bind to client-specified ports.
