c7c3ef3b9c Cooja: add Msp802154BitErrorRadio interface
The interface more accurately models bit errors due to signal fading as observed in IEEE 802.15.4-compatible radios, such as CC2420 and CC2520.

eb4bdde9ca Finish the transmission at the end of a correct packet
This patch restores the original behaviour of Cooja when
the transmitted packet is correct (which is true in a vast majority
of cases).

In case of a wrong outgoing packet (wrong length, wrong preamble)
the transmission will end when the radio changes its state (which
should always happen after transmitting a packet).

Benchmarks with RPL (33 runs, 50 nodes, 3 hours of simulated time each)
yield the same results (PDR, delay, number of transmitted packets)
as with the unmodified Cooja.

034a97eed2 Don't generate a zero-length packet in case of errors.
The packet converter used to generate packets of length zero
when it encountered errors during conversion. This caused
exceptions in packet analyzers.

Now the converter returns null in case of error. Appropriate
checks have been added to the code that uses the return value.

eae25d622d Check the frame preamble and MPDU length before parsing
Due to errors in mspsim and/or radio drivers, packets of incorrect
length are sometimes transmitted. The length might be larger than
the 127-byte maximum (considered negative in the current code)
or not matching the actual number of transmitted bytes.
This leads to wrong packet delimiting when converting from
the mspsim-level stream of bytes to Cooja-level packets
causing unhandled exceptions that terminate the simulation.

This patch checks the frame preamble (0000007A) and the length field.
If they are wrong, no decoding attempt is done.

The transmitted bytes are still delivered to the receivers untouched.
The connection is terminated when the radio state is changed (which alway
s happens when TX is done).

67427b9b86 Improve multichannel support for Cooja.
* Fix CCA detection in Cooja in the case when the receiver swicthes on the right channel during an ongoing transmission. Always add a connection on transmission, even when the channel is not correct. Initially the connection is in a dormant state; this mimics what Cooja is doing when the receiver radio is turned off;
when the receiver is turned on and switched to the right channel, `updateSignalStrengths()` is called, and the connection starts to recieve PHY-level traffic.

* Add "channel" property for DGRM edges.

* Avoid cross-channel interference on DGRM and MRM radio mediums

0a63922fa2 Buttons: Move implementation of button routines to Button class
The implementation of clickButton(), pressButton(), and releaseButton()
can be shared accross the several node-dependent implementations as
they use the node-dependent doPressButton() doReleaseButton() routines.

9d27b181c1 [cooja/mspsim] Msp802154Radio: Fix maximum power indicator
Previously getOutputPowerIndicatorMax() returned the fixed value 31.
This is valid for e.g. the mspsim CC2420 radio implementation but not for the CC2520 implementation where the maximum returned value is 9.

Thus to fix transmission range issues (for example for Wismote node) the maxium value provided by the radio implementaiton must be used.
