Kernel: Stack pointer out of bounds now panics with a message

Kernel: Cleanup process creation for userspace

Kernel: Stack pointer is validated when updated
...
This allows us not to fail stack pointer when in syscall since
interrupts use their own stack

Kernel: Add barebones per process virtual addresses
...
We now assign every (userspace) process its own MMU which we load
in scheduler. This allows every process to have separate virtual
address space.
This is very hackish implementations but it works for now

Kernel: Process is not reference counted any more
...
This was not necessary and it made things needlessly complicated

Kernel: We can create basic userspace processes
...
These are still allocated on the kernel memory

BAN: Move RefPtr to its own file and create New.h
...
New.h contains definitions for placement new operators and
BAN::allocator and BAN::dealloctor

Kernel: cleanup includes

I went quickly went through all files since I found some weird
includes :D

Kernel: Thread is no longer RefCounted
...
This makes developement with Scheduler much easier against compiler
optimizations. I could now remove the pragma GCC optimize stuff.

Kernel: Add basic concept of Processes
...
We now create Shell as a process that has its own threads

Kernel: Thread creation now takes void(*)() as entry and void* as data
...
This simplifies threading for the future and gets rid of (undefined?)
cast of member function pointer to address

Sleeping is definately broken

Kernel: Improve multithreading support
...
We can now use arbitary BAN::function<void(...)> as the Thread.
I also implemented multithreading for i386 since it was not done
on the initial multithreading commit.

Kernel: Implement somewhat functioning multithread support
...
This still uses only a single cpu, but we can now have 'parallelization'
This seems to work fine in qemu and bochs, but my own computer did not
like this when I last tried.
I have absolutely no idea how multithreading should actually be
implmemented and I just thought and implemented the most simple one I
could think of. This might not be in any way correct :D
