This should work as long as TTY provides only valid utf8.
If the utf is invalid, assertion fails and the shell dies.

Kernel: Remove offset from OpenFileDescriptor
...
This is now handled on the libc side. There might be reasons to
have it in kernel side, but for simplicity's sake I'm moving it
to libc for now :)

Kernel: We add FixedWidthAllocators on demand
...
On SYS_ALLOC we will add a new FixedWidthAllocator if the old ones
are already full or we don't have one with proper size. This allows
arbitary number of allocations as long as you have enough memory
available :)
Next I will be writing a general allocator for allocations larger
than 4096 bytes which should make SYS_ALLOC syscall complete :)

Kernel/LibC: add free function for FixedWidthAllocator
