Realtime option group). The implementation should be complete, but is
totally untested yet.

* Trivial adjustments of code using mutexes. Mostly removing the
mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
spinlock being held. The spinlock is released while waiting, of
course. This function is useful in cases where the existence of the
mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
another team needs to be locked to use mutex_lock_threads_locked().
Before it required a semaphore-based mutex implementation.

defined/undefined to numeric values (0 for undefined). This allows for
trace levels.
* Set SYSCALL_TRACING_IGNORE_KTRACE_OUTPUT default to 1, since this is
what one usually wants.

but also prints post syscall entries not matching the filter, if the
respective pre syscall entry matched. This way one also sees the syscall
return values. Works only in forward direction ATM.

structure. They are properly inherited and updated on
fork(), load_image(), and exec().
* Implemented the get[e]{u,g}id(), set[[r]e]{u,g}id() family for real.
* getgroups() also calls the kernel now, but only returns the effective
group ID. Supplementary groups support is still missing.

_kern_ktrace_output() syscall, since it will be stored in a separate
entry anyway.

kSyscallParametersInfos to kExtendedSyscallInfos) and added "name"
field. Now the classes for syscall kernel tracing don't need to lookup
the syscall function symbol anymore, which speeds up printing/filtering
of those entries dramatically.

So now there's a central place to enable tracing in general and for
individual components.

parameters, now. We print 64 bit values correctly, and also fetch
strings from userland and print them.

* With post syscall debugging enabled, the x86 syscall handling didn't
remove all parameters from the stack after calling the respective user
debugger hook. Should have been harmless though, since the following
code didn't rely on the stack being in order.
* Added syscall pre/post (kernel) tracing functions
trace_{pre,post}_syscall(). They are generic, but need to be invoked
by the architecture specific syscall code. Currently only done for
x86.
