Fix too short 6LoWPAN reassembly timeout
[avr] Removed usage of deprecated MCUSR

Since avr-libc 1.8.0 MCUSR is marked as poison as it was replaced by the
correct name MCUCSR.
Thus code still using the old MCUSR name does not compile anymore.

This commit replaces usages of former MCUSR by its new name MCUCSR and
modifies the alias fallback accordingly.
llsec: Renamed ccm to ccm_star & Renamed llsec regression test
avr: changed EEPROM writing to updating to reduce buring of new EEPROM cells
Makefile.inga: Fixed Race condition when flashing multiple Motes on
fast computers (Fixes #25)
serialdump: exit without error on CTRL+C
serialdump: updated binary version
serialdump: updated binary version (macos)
platform/inga: added udev-rule example for inga
platform/inga: Replaced sky motelist script by simpler inga specific
motelist script
Merge pull request #2 from comawill/pull-req/serial-exit

serialdump: updated binary version (macos)
[cooja-platform] Include eeprom.h to avoid implicit declaration warning
[cooja-platform] Remove unused variable 'shortaddr'

This variable was set but never used in the code
[cooja-platform] Add cast to linkaddr_t to avoid warning
[cooja-platform] Fixes for slip-bridge compatibility

* 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.
[cooja/serialsocket] Do not throw UnsupportedOperationException()

Added pack() call to packPlugin() and removed exception throwing.
This issue was caused by merging with mainline version of SerialSocket.
Button: Move common interface visualization to Button class

The implementation of a simple JPanel with a JButton was only code
duplication accross the several button implementations.
SkyButton: Reduce dependency on SkyMote

Placed call to setButton() in implementation-specific functions
doPressButton() and doReleaseButton() as in ContikiButton.
Button: None of the buttons will saves its state

Saving a buttons state in simulation file is not required as its state
is much too volatile.
Button: Add doPressButton() and doReleaseButton() to Button class

As every Button has a node-specific implementation part, this should be
the minimal interface to the backend node emulator for pressing and
releasing a button.
