o Support callback types NONE, E.164, AUTH and CBCP.

Browse Source 
(see the new ``set callback'' and ``set cbcp'' commands)
o Add a ``cbcp'' log level and mbuf type.
o Don't dump core when \T is given in ``set login'' or
  ``set hangup''.
o Allow ``*'' and blanks as placeholders in ppp.secret and
  allow a fifth field for specifying auth/cbcp dialback
  parameters.
o Remove a few extraneous #includes
o Define the default number of REQs (restart counter) in defs.h
  rather than hardcoding ``5'' all over the place.
o Fix a few man page inconsistencies.

.It set callback [none|auth|cbcp|E.164 *|number[,number]...]...
If no arguments are given, callback is disabled, otherwise,
.Nm
will request (or in
.Ar direct
mode, will accept) one of the given protocols. If a request is NAK'd
.Nm
will request another, until no options remain at which point
.Nm
will terminate negotiations.
The options are as follows (in this order of preference):
.Pp
.Bl -tag
.It auth
The callee is expected to decide the callback number based on
authentication. If
.Nm
is the callee, the number should be specified as the fifth field of
the peers entry in
.Pa /etc/ppp/ppp.secret .
.It cbcp
Microsofts callback control protocol is used. See
.Dq set cbcp
below.
.It E.164 *|number[,number]...
The caller specifies the
.Ar number .
If
.Nm
is the callee,
.Ar number
should be either a comma seperated list of allowable numbers or a
.Dq \&* ,
meaning any number is permitted. If
.Nm
is the caller, only a single number should be specified.
.Pp
Note, this option is very unsafe when used with a
.Dq \&*
as a malicious caller can tell
.Nm
to call any (possibly international) number without first authenticating
themselves.
.It none
If the peer does not wish to do callback at all,
.Nm
will accept the fact and continue without callback rather than terminating
the connection.
.El
.Pp
.It set cbcp Op *|number[,number]... Op delay Op retry
If no arguments are given, CBCP (Microsofts CallBack Control Protocol)
is disabled - ie, configuring CBCP in the
.Dq set callback
command will result in
.Nm
requesting no callback in the CBCP phase.
Otherwise,
.Nm
attempts to use the given phone
.Ar number Ns No (s).
.Pp
In server mode
.Pq Fl direct ,
.Nm
will insist that the client uses one of these numbers, unless
.Dq \&*
is used in which case the client is expected to specify the number.
.Pp
In client mode,
.Nm
will attempt to use one of the given numbers (whichever it finds to
be agreeable with the peer), or if
.Dq \&*
is specified,
.Nm
will expect the peer to specify the number.
