The lock_memory()/unlock_memory() functions cannot be implemented right
now, as the NewOS VM doesn't support locking.

TRACE() macro. Renamed the old TRACE macro to TRACEPFAULT.

Made the "name" argument const for create_area_etc() and vm_map_physical_memory().
Moved some common conversion code (BeOS to NewOS VM constants) to separate
functions to clean them up a bit.
create_area() now automatically sets LOCK_KERNEL if the area is to be created
in kernel space (as I would guess BeOS does, too).

in the kernel.
Use the new delete_area_etc() call for other needs.

delete_area() now only allows to delete areas you have created
yourself before from userland, again.
The kernel's delete_area() still allows everything, though.

delete. Added a comment how the security should be improved by adding another
restriction.
Also mentioned that it's probably a bad idea that vm_delete_region() will
not wait until the region has been freed, but just "mark" it as to be freed.

that will call the internal vm_*() calls. This will make it easier to just
drop in another VM.
Also (partially - Ingo was faster) introduced the new syscall naming scheme
_kern_ & _user_ prefixes to them into the system namespace, and no longer
clobber the application namespace.
Removed the now unused user_vm_create_anonymous_region() call.

field to the thread structure to keep track of the current state.
forbids/permits can be nested.

Implemented realloc().
Adapted all other sources, some minor cleanups in some files as well.

which is now used thorough the VFS code instead of user_strncpy().
fd.c: Replaced some return codes.
vfs.c: joined attr_dir_open(), and attr_dir_open_fd(), added sys_/user_
calls to access attributes, and attribute directory.

benaphores; benaphores aren't that beneficial in kernel land, the benaphores
are a way to reduce the number of kernel calls.
They can now only be released by the same thread who originally acquired it.
Included other changes geist (change 1499) did to a) fix some bugs, and
b) reflect the changes made to the mutexes.
Cleaned the files a bit up, all the commented dprintf()s in elf.c are now
deactivated through a macro.

Fixed some bugs in fd.c (how many more bugs can be in a small file like this? :-).
Added the syscalls for sys_open_dir(), and sys_create_dir().
