Conrad Pankoff aee9317d86 Kernel: Refactor MemoryManager to use a Bitmap rather than a Vector ...

This significantly reduces the pressure on the kernel heap when
allocating a lot of pages.

Previously at about 250MB allocated, the free page list would outgrow
the kernel's heap. Given that there is no longer a page list, this does
not happen.

The next barrier will be the kernel memory used by the page records for
in-use memory. This kicks in at about 1GB.
