kernel: atomic_*() functions rework

* No need for the atomically changed variables to be declared as
volatile.
* Drop support for atomically getting and setting unaligned data.
* Introduce atomic_get_and_set[64]() which works the same as
atomic_set[64]() used to. atomic_set[64]() does not return the
previous value anymore.

x86_64 changes :
added atomic*64() functions
use int32 instead of long

BeOS build fixes:
* On BeOS compatible host platforms we must not include
BeOSBuildCompatibility.h, but HaikuBuildCompatibility.h.
* Fixed errno usage in command_cp.cpp.
* Fixed fssh_ioctl().
* fssh_set_sem_owner() doesn't invoke BeOS's set_sem_owner() anymore or
otherwise the FS's semaphores are assigned to the kernel.
* Commented out <string.h> functions that don't exist under BeOS (and aren't
used anyway).

Beginnings of a new, better portable FS shell with Haiku FS interface.
Doesn't do anything ATM, but already provides the required system
interface (VFS, caches, POSIX functions).
