Update contiki to support more cpus
Update to latest contiki code
Add utility to help with timer impl tests

Just a quick hack to add a timestamp in front of each whole line.
Timer and clock test routines

A set of processes that use clock and timer routines for known expected
durations, and some python host code that compares that to reality

Limited by speed of console printing, but still helpful for sanity
checking.
Work around python bash completion bug

[timer-tests] Make all tests run

Can't figure out how to make contiki run a set of processes one by one, and
it's not the aim of my current project, so just run them all in a row inside
one big test process.
[timer-tests] Add test for clock_seconds()
[timer-tests] Add basic rtimer test
[timer-tests] Add more ranges of clock_delay_usecs
Update to latest clock implementation in core
timer-test: add documentation
platform/stm32-e407/Makefile.stm32-e407 (MCLK): our clock is 48 MHz, not 32 MHz
platform/stm32-e407/contiki-main.c: show PLL configuration and resulting clocks
Update contiki to get new clock routines
Work with merges only, make collaborators much happier :)
Update contiki core, always and forever
Merge remote-tracking branch 'upstream/master' into HEAD

Conflicts:
	contiki
platform/freertos/contiki-main.c (contiki_main): start the resolver
update contiki submodule revision
