a7e5157fd9 core: add thread_get() 
Remove PID check duplication in `thread_getstatus()` and
`thread_getname()`.

bf6548ca30 core: shadowing in priority_queue_print 
The variable `node` shadows the parameter `node`. The access of
`node->first` would not compile, because there is no member `first` in
`priority_queue_t`.

c2b0423918 core: renamed KERNEL_PID_NULL to KERNEL_PID_UNDEF 
As @authmillenon pointed out the "null" in the old name is somewhat
misleading, since the actual value is -1.

0836cd0b18 core: moved definition of KERNEL_PID_NULL 
kernel_pid_t is defined in kernel_types.h, thus it makes sense to move
the macro for an invalid kernel pid there, too.

9e3830a72b core: only store the stack size for DEVELHELP 
`tcp_t::stack_size` is only examined by the shell command `ps` and
`DEBUG_PRINT`. For the latter one only if `DEVELHELP` was enabled.

This PR guards the member `tcp_t::stack_size` in `#ifdef DEVELHELP`.
Only if DEVELHELP was activated its value get printed by `ps`.

Closes #1287.

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.

5e8c0c9058 converting tabs to spaces in core (#1439) 
This PR converts tabs to white spaces.
The statement I used for the conversion:
'''find . -name "*.[ch]" -exec zsh -c 'expand -t 4 "$0" > /tmp/e && mv /tmp/e "$0"' {} \;'''
Afterwards, I had a quick overview of the converted files to prevent odd indentation.

9cabdb3043 core/sched: clean up 
- remove stray spaces
- remove TODOs:
    - MODULE_HWTIMER is not a module anymore
    - checking for NULL is necessary, at least without API changes:
      `sched_task_exit` sets `sched_active_thread` to `NULL`, then exits,
      afterwards `cpu_switch_context_exit` calls `sched_run`

919cddef19 make: rename VERSION into RIOT_VERSION 
Building MSP boards gives an error, because `VERSION` is somewhere
defined in their toolchain as an integer.

This PR renames `VERSION` into `RIOT_VERSION`, because that's what it
is.

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.

a21c3f45bc core: remove unnecessary tests in sched.c 
The scheduling gets activated by `kernel_init()` calling
`cpu_switch_context_exit()`. Before this `sched_run()` won't be called.
When it gets called, at least the main thread and the idle thread are
spawned. The idle thread won't die / get killed. So there always is at
least one thread in `runqueue_bitcache`.

Closes #19.
