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.

Kernel: Tweak some String&& => const String&.
...
String&& is just not very practical. Also return const String& when the
returned string is a member variable. The call site is free to make a copy
if he wants, but otherwise we can avoid the retain count churn.

VM: Don't remap each Region page twice in page_in().
...
page_in_from_inode() will map the page after reading it from disk, so we
don't need to remap it once again.

Kernel: Make the Process allocate_region* API's understand "int prot".
...
Instead of having to inspect 'prot' at every call site, make the Process
API's take care of that so we can just pass it through.
