74fcb219ab Enhanced Google domain detection in apache-fakegooglebot

avoids to resolve fake Google domains.

36919d9f97 ssh.conf: Fix disconnect "Auth fail" matching
The regex for matching against "Auth fail" disconnect log message does
not match against current versions of ssh.  OpenSSH 5.9 introduced
privilege separation of the pre-auth process, which included
[logging through monitor.c](http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/monitor.c.diff?r1=1.113&r2=1.114)
which adds " [preauth]" to the end of each message and causes the log
level to be prepended to each message.

It also fails to match against clients which send a disconnect message
with a description that is either empty or includes a space, since this
is the content in the log message after the disconnect code, per
[packet.c:1785](http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/packet.c?annotate=1.215),
which was matched by \S+.  Although I have not observed this yet, I
couldn't find anything which would preclude it in [RFC
4253](https://tools.ietf.org/html/rfc4253#section-11.1) and since the
message is attacker-controlled it provides a way to avoid getting
banned.

This commit fixes both issues.

189265a323 Asterisk security log: accept SessionID of PJSIP events
Unlike chan_sip and manager, PJSIP populates SessionID using
Call-Id header of a related SIP message.
As Call-Id of a SIP message can contain almost anything,
the regular expression for SessionID has been loosened.
