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

Also only process can now add threads to scheduler. Nobody should
have raw access to scheduler and everything should be through

BAN: Add {TRY,MUST}_REF for references
...
It is annoying that we have to have separate macros for these but
I can't find a way to cleanly return lvalue reference from statement
expression. Currently we cast the reference to pointer and return
unreference the pointer outside of the expression.
This feature will probably not be used any time soon, but atleas
it is implemented if I need it one day

BAN: Variant now works with references
...
References can be assigned with the set() method. Construction nor
assigment operators cannot be used with references to avoid ambiguity
with what assignment to reference does.
You can set the underlying reference with the set() method and access
it with the get() method.
The references are stored as pointers to the object under the hood
which means that size of a reference is sizeof pointer.
