da550bc913 introduce HWTIMER_SPIN_BARRIER (API change) 
Boards should define HWTIMER_SPIN_BARRIER that is used to decide
whether it makes sense to set a timer and yield or call hwtimer_spin
instead.
Used by `core/hwtimer.c` and `sys/vtimer/vtimer.c`.
A default value is provided and a warning is printed when it is used.

983d056c75 core: harmonizes the data type for the process ID 
Instead of using differing integer types use kernel_pid_t for process
identifier. This type is introduced in a new header file to avoid
circular dependencies.

e1705622b7 vtimer: fix crash on spurious hwtimer callback 
It seems that there are corner cases where a vtimer was removed, but
still there comes a hwtimer callback. This is a bug somewhere in the
vtimer or hwtimer. If there still was a vtimer set, then the next one
gets called before its time. If there was no other vtimer scheduled,
then `timer->action(timer)` crashes.

This PR simply fixes the crash, but does not attempt to find the more
fundamental bug.

840c0f0a57 make: detect their module name automatically 
For many modules the `Makefile` contains a line like
```
MODULE:=$(shell basename $(CURDIR))
```
This conclusively shows that we do not have to set the module name
manually.

This PR removes the need to set the module name manually, if it is the
same as the basename. E.g. for `…/sys/vtimer/Makefile` the variable
make `MODULE` will still be `vtimer`, because it is the basename of the
Makefile.

2231a315d4 vtimer: fix callback usage 
There is no need to test the "handler" set in the vtimer struct, and
have some code executed then. We just can make the code to execute the
handler. To lengthy `if else if`, just a call.

07b0cd8863 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.
