only a few events can be watched (team creation/deletion/exec, thread creation/
deletion/name changes). The functions start_system_watching()/
stop_system_watching start/stop watching events.

- Reimplemented mutex to use the _kern_mutex*() syscalls.
- The initializer functions cannot fail anymore -- changed their return type
to void.
- Changed the initializer function semantics to not copy the name by default
anymore (as in the kernel). Also added *_etc() versions of them that take an
additional flags.
- Added static initializer macros.
- Made the mutex (and thus recursive_lock) lock functions non-interruptable.
- Got rid of the "lazy" version. They are no longer needed, since the
initialization of the standard types can be done statically and cannot fail.
* Adjusted libroot, runtime loader, and other code using the private libroot
locking primitives to the new semantics.
* pthreads mutexes and condition variables:
- Reimplemented using the _kern_mutex*() syscalls.
- Consistently use POSIX error codes.
- Fixed some not quite POSIX compliant behavior.

* Implemented a tiny bit more sophisticated version of
estimate_max_scheduling_latency() that uses a syscall that lets the scheduler
decide.

When initializing driver settings, make sure to set the parameter count to 0,
because these settings have not been parsed yet. This allows us to safely free
the settings. Freeing the settings is triggered in load_driver_settings() if
we encounter settings which have been originally loaded by the boot_loader,
which might be stale. I think the bug would trigger for settings which had been
loaded by the boot_loader but had never been parsed.
With this change, I can use the userlandfs on all my machines.

Also added an empty stub for _thread_do_exit_notification() when compiling for GCC2.

* relocated Trash dirs to volume roots by modifying find_directory() to report the trash location as volume/Trash.
* FSUtils no longer creates /home/Desktop on every volume.
* TrashWatcher now keeps icons in sync on all volumes.
* Simplified FSGetDeskDir since it no longer has to worry about getting the desk directory on any volume other than the root.
* Relocated trash context menu logic to BContainerWindow so it can also be used at the volume roots.
* DesktopPoseView now creates a virtual Trash pose representing the trash contents as before.
* Corrected typo: Model::WriteAttrKillForegin() -> Model::WriteAttrKillForeign().
Closes ticket #5245.

system_time_nsecs(), returning the system time in nanoseconds. The function
is only really implemented for x86. For the other architectures
system_time() * 1000 is returned.

difference that the initialization function has an additional void* argument,
so that it is suitable for initializing stuff in objects.

* Split locks.cpp into mutex.cpp, recursive_lock.cpp, and rw_lock.cpp (new
subdirectory locks/).
* runtime_loader no longer includes the rw_lock, allowing removal of the TLS
dependency again.

as a mutex, but allocates its semaphore lazily. This comes at the cost of an
additional atomic_add() when the semaphore has actually to be acquired, but
saves the semaphore creation completely in single-threaded programs and in
any program when there's no lock contention.

"etc" are put there now, as well.

returned by open() aren't suitable for directory iteration and because checks
have to be performed (like whether this is a directory at all and whether the
user has read permission).
* Added __create_dir_struct() for the attribute, index, and query open
functions to use instead.

libroot. The mutex is a simple benaphore, the rw_lock is pretty much the same
as the one from libkernelland_emu but uses a mutex per lock instead of emulating
a global thread lock. Also added MutexLocking and RWLock{Read|Write}Locking and
AutoLockers based on them. It's cased with __cplusplus so the locks are also
usable from C. Everything's currently exposed in shared/private/locks.h but I
think we should make these locking primitves public.

* Got rid of <dirent_private.h> -- the __DIR structure is private to dirent.c,
now. The attribute directory, index directory, and query functions use the
the public POSIX API, so does the kernel module code. Those components were
not initializing the structure correctly anymore since the introduction of
telldir()/seekdir().

each attribute access needed 3 syscalls, now only one as it should.
* Renamed the new Haiku call fs_open_attr() to fs_fopen_attr(), and added a new
function fs_open_attr() that takes a path (same semantics as the
fs_[f]open_attr_dir() functions already present in BeOS).
* Merged former _kern_open_attr(), and _kern_create_attr() into one syscall.
* Cleaned up vfs.h.
