Added some x86_64 system/kernel headers and kernel Jamfiles. * Not all of these headers are correct yet, just adding what's necessary to get things to compile for the time being.

kernel/x86_64: remove memset and memcpy from commpage There is absolutely no reason for these functions to be in commpage, they don't do anything that involves the kernel in any way. Additionaly, this patch rewrites memset and memcpy to C++, current implementation is quite simple (though it may perform surprisingly well when dealing with large buffers on cpus with ermsb). Better versions are coming soon. Signed-off-by: Paweł Dziepak <pdziepak@quarnos.org>

x86: move x86_userspace_thread_exit() from user stack to commpage x86_userspace_thread_exit() is a stub originally placed at the bottom of each thread user stack that ensures any thread invokes exit_thread() upon returning from its main higher level function. Putting anything that is expected to be executed on a stack causes problems when implementing data execution prevention. Code of x86_userspace_thread_exit() is now moved to commpage which seems to be much more appropriate place for it.

(COMMPAGE_ENTRY_FIRST_ARCH_SPECIFIC + 1)
Fixed commpage for x86_64. Since the commpage is at a kernel address, changed 64-bit paging code to match x86's behaviour of allowing user-accessible mappings to be created in the kernel portion of the address space. This is also required by some drivers.
