Kernel: fix some math in physical ranges
...
I allocated 1 bitmap page per 8 data pages. Bitmap page can actually
store 8*PAGE_SIZE data pages.
Also properly set last bits in bitmap. I did not care about endianness
but now we set the bits on unsigned long longs instead of bytes.

PhysicalRange is now much simpler bitmap. This makes expanding
PhysicalRange API much easier.

Kernel: Change PageTable API

Getting free pages not reserves them, so you don't have to hold
the page table lock :)
