Travis: disable 02-sky-ipv6-udp test b/c it's still flaky
Merge pull request #234 from darconeous/pull-requests/platform-econotag-uip-rpl-override

platform/econotag: Allow RPL and Router settings to be overridden.
cpu/avr: Added "AVRDUDE_MCU" configuration parameter.
core/net/uip: Experimental support for loopback capability.

Enabled via setting UIP_CONF_LOOPBACK_INTERFACE to 1.
avr/usb/rndis: Large refactoring/cleanup.

Removed a lot of jackdaw-specific stuff and made it more flexible.
avr/radio/rf230bb: Cleanup and add hooks.

Removes references to the old rf230 code, which isn't being used
anymore.
avr/bootloader.c: Now compatible with bootloaders which always run first.

The boot loader now knows when to go into bootstrap mode by
looking for a specific EEPROM value. Also updated code style
to match Contiki code style guidelines.
Various tweaks to the uip network stack.
avr-ravenusb/cdc_task: Fix compile issues.

A lot more changes are in the pipeline, but compiling is a good start.
cpu/avr/usb/serial: Updates to CDC serial implementation.

jackdaw: Move cdc_task and sicslow_ethernet over to ravenusbstick.

The "Jackdaw" firmware for the Atmel RZUSBStick could be very useful
on other platforms, but it's implementation is highly integrated into
the `avr-ravenusb` platform. This commit takes the first step toward
changing that, by moving the cdc_task and sicslow_ethernet code out
of the `avr-ravenusb` platform and into the `ravenusbstick` example.
platform/avr-ravenusb: Slight improvement to the RNG.
platform/avr-ravenusb: Added experimental mechanism to switch RDC at runtime.
