[cooja-platform] Fixes for slip-bridge compatibility

Browse source 
* Added dev/uart1.h header file to cooja platform
* Added slip arch stub
* Suppress examples putchar definition as cooja platform provides its own

Note that the uart1.h file should only be an intermediate solution.
A generic contiki-wide definition for uart handling is required as each
platform defines its own varying set of uart functions.

/*
Copied from mc1322x/dev/cpu.
This file exists as a work-around for the hardware dependant calls
to slip_arch_init.
Current the prototype for slip_arch_init is slip_arch_init(urb)
and a typical call is something like
slip_arch_init(BAUD2URB(115200))
BAUD2UBR is hardware specific, however. Furthermore, for the sky
platform it's typically defined with #include "dev/uart1.h" (see
rpl-boarder-router/slip-bridge.c), a sky specific file. dev/uart1.h
includes msp430.h which includes the sky contiki-conf.h which
defines BAUD2UBR.
To me, the correct think to pass is simply the baudrate and have the
hardware specific conversion happen inside slip_arch_init.
Notably, most implementations just ignore the passed parameter
anyway. (except AVR)
