Kernel: Add a heap memory allocator
...
This is the first time I've actually dropped liballoc in favor of writing my own implementation.
Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job.
But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code!

Rename physical "pages" to "frames"
