Add new PC300 WAN driver (courtesy Cyclades), and my own changes: 

* patch added stuff to include/linux.  move these three new headers
  to drivers/net/wan.
* change the code to support these changes
* slightly better Config.in entry. needs more work, though.

Cyclades-PC300 support
CONFIG_PC300
This is a driver for the Cyclades-PC300 synchronous communication
boards. These boards provide synchronous serial interfaces to your
Linux box (interfaces currently available are RS-232/V.35, X.21 and
T1/E1). If you wish to support Multilink PPP, please select the
option below this one and read the file README.mlppp provided by PC300
package.
If you want to compile this as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read Documentation/modules.txt. The module will be
called pc300.o.
If you haven't heard about it, it's safe to say N.
Cyclades-PC300 Sync TTY (to MLPPP) support
CONFIG_PC300_MLPPP
Say 'Y' to this option if you are planning to use Multilink PPP over the
PC300 synchronous communication boards.
