kernel: Make use of the new ConditionVariable lock-switching APIs in a few places.

kernel/daemon: Sleep as long as possible between runs.

Avoids waking up every 100ms to do nothing.

Replaced no longer necessary send_signal_etc() work-arounds for
resume_thread().

* The kernel daemon no longer hold its lock when calling the registered hooks.
* This fixes bug #5421.

Avoid using DoublyLinkedList internals.

* This should hopefully fix the broken kernel - this code relied on clearing
the next/previous pointers. There might be more, though.

Fixing warnings under GCC4 in preparation to enable -Werror there as well:
* Replaced the use of offsetof() for structs that aren't PODs. Add a
offset_of_member() macro to util/khash.h because that's what it's used for
in our cases.
* Change the signature of add_debugger_command()/remove_debugger_command() on
GCC > 2 to avoid the depricated conversion from string constants to char *.
* Adding some "suggested" parenthesis. I know that not everyone likes that, but
it pointed out at least one bug that is fixed here as well.

* The kernel daemon now uses a recursive lock instead of a mutex. This fixes
bug #3082.
* Also, it now allows to remove daemons in their hook function.
* Added a "daemons" KDL command that dumps all registered kernel daemons, and
resource resizers.

* Refactored the kernel daemon code into a class.
* Added a second kernel daemon service, resource resizer, which is
mainly supposed to be used for resizing allocations asynchrounously.

* Initialize all static mutexes in the kernel through a MUTEX_INITIALIZER()
and remove the then unneeded mutex_init() for them.
* Remove the workaround for allowing uninitialized mutexes on kernel startup.
As they are all initialized statically through the MUTEX_INITIALIZER() now
this is not needed anymore.
* An uninitialized mutex will now cause a panic when used to find possibly
remaining cases.
* Remove now unnecessary driver_settings_init_post_sem() function.

Daemons are now spawned with "new", and thus they should be sent back using
"delete", not free().

the C list mechanism which also makes the code nicer.
