This patch-set introduces the CAIF protocol Stack.

The "Communication CPU to Application CPU Interface" (CAIF) is a packet based
connection-oriented MUX protocol developed by ST-Ericsson for use with its
modems.

* CAIF provides a socket interface which can be used to open virtual AT
  channels, create and configure GPRS Data connections.

* A CAIF Network device is also provided for GPRS access.
  This interface can be managed with socket IOCTLs or RTNL.

* A kernel interface is provided allowing Kernel modules to use CAIF.

* A serial link layer layer implemented as a line discipline is currently 
  implemented. Other link interfaces may be contributed at a later stage.
