test: fix bloom filter test
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`.

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.
