Remove ISDN4BSD (I4B) from HEAD as it is not MPSAFE and

parts relied on the now removed NET_NEEDS_GIANT.
Most of I4B has been disconnected from the build
since July 2007 in HEAD/RELENG_7.

This is what was removed:
- configuration in /etc/isdn
- examples
- man pages
- kernel configuration
- sys/i4b (drivers, layers, include files)
- user space tools
- i4b support from ppp
- further documentation

Discussed with: rwatson, re

-.Sh NAME
-.Nm isdnphone
-.Nd telephone dialing and more for isdn4bsd
-.Sh SYNOPSIS
-.Nm
-.Op Fl d
-.Op Fl h
-.Op Fl k Ar string
-.Op Fl n Ar number
-.Op Fl u Ar unit
-.Op Fl v
-.Op Fl w
-.Sh DESCRIPTION
-The
-.Nm
-utility
-is part of the isdn4bsd package and is used to handle dialing and hangup
-for the telephone control interfaces
-.Pa /dev/i4bteld Ns Aq Ar n .
-.Pp
-Options are provided to dial out or hang up using command line parameters
-(for use in scripts) or, if none of those options are specified, bring up
-a curses-based full-screen interface.
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.It Fl d
-Enable debugging message display.
-.It Fl h
-Hang up a possibly open telephone connection on the selected interface.
-.It Fl k
-Send the specified string using the keypad facility information element.
-.It Fl n
-Dial the specified number on the selected interface.
-.It Fl u
-Set the unit number to specify the interface used.
-.It Fl v
-Enable verbose result messages for dialling (-n and -w)
-.It Fl w
-After dialling (using the -n option), wait for the first result message.
-.El
-.Sh FILES
-.Bl -tag -width indent -compact
-.It Pa /dev/i4bteld Ns Aq Ar n
-.El
-.Sh EXAMPLES
-The command:
-.Dl "isdnphone -n 1234"
-.Pp
-dials calls the number 1234 to establish a call on
-.Pa /dev/i4btel0
-.Sh AUTHORS
-The
-.Nm
-utility and this manpage were written by
