TCP connect. The connection phase of the SSH session is time-sensitive (due
to server side login grace periods) and is frequently interactive (e.g.
entering passwords). The ultimate interactive/bulk TOS/DSCP will be set after
authentication completes.

On some platforms (at least older HP-UXes such as 11.11, possibly others)
setting SA_RESTART on signal handers will cause it to not interrupt
select(), at least for calls that do not specify a timeout. Try to
detect this and if found, don't use SA_RESTART.
POSIX says "If SA_RESTART has been set for the interrupting signal, it
is implementation-dependent whether select() restarts or returns with
[EINTR]" so this behaviour is within spec.
sigaction(2). This wrapper blocks all other signals during the handler
preventing races between handlers, and sets SA_RESTART which should reduce
the potential for short read/write operations.

connect, not just readable. Prevents a timeout when the server doesn't
immediately send a banner (eg multiplexers like sslh) but is also slightly
quicker for other connections since, unlike ssh1, ssh2 doesn't specify
that the client should parse the server banner before sending its own.

host/port was added in 2001 as an alternative to host:port syntax for
the benefit of IPv6 users. These days there are establised standards
for this like [::1]:22 and the slash syntax is easily mistaken for CIDR
notation, which OpenSSH now supports for some things. Remove the slash
notation from ListenAddress and PermitOpen. bz#2335, patch from jjelen

Also be more strict about handling \r characters - these should only

the limit starts being computed as soon as possible, ie after the second
