VMM: Make it so much gooder
...
There are still some fixes to be made, but I think this is already way cleaner than before.

Kernel: Move VMM from a class to a namespace
...
Also, rename the ugly Paging::VirtualMemoryManager name to just 'VMM'. Which is now used instead of kernelVMM.

Port liballoc to get proper kmalloc/kcalloc/krealloc/kfree functions.
...
Yes, that's not completely-from-scratch.
But let's be honest, am I going to do everything from scratch? Probably not. I'm not making my own bootloader.
And making a proper smaller-than-4-KB allocator is not something I want to do.
Plus, liballoc works perfectly in this rewrite, seeing as the MM code actually works, instead of leaking all your poor memory
And liballoc_{lock, unlock} can be actually defined, since we have spinlocks here!

Kind of a more catchy name, isn't it?
