[PATCH] isdn4linux: Siemens Gigaset drivers - M105 USB DECT adapter

And: Tilman Schmidt <tilman@imap.cc>

This patch adds the connection-specific module "usb_gigaset", the hardware
driver for Gigaset base stations connected via the M105 USB DECT adapter.  It
contains the code for handling probe/disconnect, AT command/response
transmission, and call setup and termination, as well as handling asynchronous
data transfers, PPP framing, byte stuffing, and flow control.
