Remove old cxconfig utility and connect new sconfig utility to the build.

The sconfig utility supports more than just cx boards, and those drivers
will make their way into FreeBSD shortly (maybe before 5.2).

Confirmed that this doesn't break the build.

-.Nd channel options management utility for Cronyx-Sigma adapter
-.Sh SYNOPSIS
-.Nm
-.Op Fl a
-.Op Ar <channel> Op Ar <option>...
-.Sh DESCRIPTION
-The
-.Nm
-utility is used for configuring the channel options of
-the Cronyx-Sigma adapter.
-.Pp
-To change channel options the channel should be free: the corresponding
-network interface in ``down'' state, the asynchronous terminal device
-.Pa /dev/tty*
-closed.
-Generally, the channel options are set up during the operating
-system startup, for example from the
-.Pa /etc/rc
-file.
-.Pp
-Note, that not all options have a sense for every particular
-case, and an attempt to set some of them can hang up the channel or
-the whole adapter.
-.Pp
-The following option is available:
-.Bl -tag -width indent
-.It Fl a
-Display full information.
-.El
-.Sh "Channel options"
-.Bl -tag -width 10n
-.It ispeed=#
-Set the receiver baud rate to the number given.
-The maximal value is 256000 bits/sec.
-In the synchronous mode the receiver baud rate is significant
-only when DPLL mode is used.
-.It ospeed=#
-Set the transmitter baud rate to the number given.
-The maximal value is 256000 bits/sec.
-In the synchronous mode the transmitter baud rate is significant
-only in the case of the internal clock source.
-If receiver and transmitter have equal data rate, then it could
-be set by specifying only the numerical argument.
-.It async
-Set the asynchronous channel mode.
-.It "hdlc, bisync, bsc, x.21, x21
-Set the synchronous channel mode: HDLC, Bisync (BSC) or X.21.
-.It ppp
-Set the link-level protocol: PpP/HDLC.  The built-in simplified synchronous PPP
-implementation is used (see RFC-1548, RFC-1549).
-.It cisco
-Set the link-level protocol: Cisco/HDLC (see RFC-1547).
-This protocol is intended for compatibility with old models of Cisco routers,
-and with early versions of
-.Tn BSD/386
-drivers.
-The extensive usage of this protocol is not recommended.
-.It ext
-Use the external link-level protocol suite (for
-.Tn BSD/386
-only).
-.It "+keepalive, -keepalive"
-Enable the automatic line state control sub-protocol.
-This setting is not significant when the external link-level protocol is used.
-.It "+autorts, -autorts"
-Enable the automatic RTS signal control.
-When enabled, the RTS signal goes up only when both halves of
-the receiver ring buffer are free and ready for receive,
-and goes down when one or both buffers are busy.
-.It "port=rs232, port=rs449, port=v35
-Set the zero channel hardware interface type.
-.El
-.Sh "Common options"
-.Bl -tag -width 10n
-.It "nrz, nrzi, manchester"
-Set the data line signal encoding.
-In the case of
-.Em NRZ
-encoding the zero bit is transmitted by the zero signal
-level, the one bit - by the positive signal level.
-In the case of
-.Em NRZI
-encoding the zero bit is transmitted by the change of
-the signal level, the one bit - by the constant signal level.
-In the case of
-.Em Manchester
-encoding the zero bit is encoded as 01 value,
-the one bit - as 10 value.
-.It "+dpll, -dpll"
-Enable the digital phase locked loop mode (DPLL).
-When enabled, the receiver timing clock signal
-is derived from the received data.
-.It "+lloop, -lloop"
-Set the local loopback mode.
-.It "+extclock, -extclock"
-Set the timing clock source of synchronous channels.  There are
-two possible variants:
-.Em "external clock"
-source or
-.Em "internal clock"
-generation.
-.Pp
-.Em "External clock"
-mode is the most common method for connecting
-external modem hardware.  In this mode the external timing
-signal is received on TXCIN pin of the connector, and it is
-used as a synchronization clock for transmitting data (TXD).
-.Pp
-In the case of
-.Em "internal clock"
-mode the transmitted data (TXD)
-are synchronized using the internal on-board timing generator,
-the internally generated timing signal is driven on the TXCOUT
-pin, and the signal on the TXCIN pin is ignored.  This mode
-is used for direct terminal-to-terminal communication,
-e.g. for connecting two computers together in a synchronous mode
-via relatively short cable.  This method should also be used
-for testing channels with an external loopback connector.
-.It fifo=#
-FIFO threshold level setup for receiver and transmitter.
-.It rfifo=#
-Hardware RTS/CTS flow control FIFO threshold setup.
-.It "+ctsup, -ctsup"
-Enable/disable interrupts on CTS (Clear To Send) signal setup (0 to 1 transition).
-.It "+ctsdown, -ctsdown"

-.It "+cdup, -cdup"
-Enable/disable interrupts on CD (Carrier Detect) signal setup (0 to 1 transition).
-.It "+cddown, -cddown"
-Enable/disable interrupts on CD (Carrier Detect) signal clear (1 to 0 transition).
-.It "+dsrup, -dsrup"
-Enable/disable interrupts on DSR (Data Set Ready) signal setup (0 to 1 transition).
