Merge pull request #783 from authmillenon/fix-at86rf231-followup

drivers : Make at86rf231_switch_to_rx() public to use with transceiver
added gettimeofday syscall

RIOT's gettimeofday needs to be called from syscalls.c to assure that gcc actually links it.

If an RTC if available and enabled it will be used instead.
Use argc and argv in shell handlers

Compare #708.

Now the tokenization of an input line is done by the shell itself. You
may quote arguments with `"..."`. Empty arguments, supplied by `""` are
preserved. Spaces in between arguments are squasheds; spaces inside
quotes are preserved.

You cannot partially quote an argument. You must not use
- `cmd "abc`,
- `cmd abc"def"`, or
- `cmd "abc"def`.
Print error message on any quoting error

core: move inISR check into sched_switch
Adds test for riot threads.

The test uses riot threads to calculate the factorial of 12,
with one thread for each multiplication. The core mutex is
used for synchronization.
