libkernel: memory: PageAllocGetter: return ref to allocator
...
Rather than returning a reference to the `OnceCell` wrapping the
allocator, return a static reference to the allocator itself. This
allows flexibility for how the allocator is wrapped.

libkernel: memory: reorganise allocators

Create a new submodule within `memory`, `allocators` which contains all
memory allocators. Also split out the `Frame` struct from the `pg_alloc`
module, allowing it to be used by other modules.

libkernel: ext4: add inode id to metadata
...
Add the proper inode and fs id to the `FileAttr` struct returned by
`getattr`. This prevents the dynamic loader from skipping files which it
considers to be hard-links (share the same inode ID).

fat32: downcase 8.3 filenames
...
Using mtools to prepare the initrd image results in an image that
exclusively uses 8.3 filenames; as per the spec, the 8.3 filenames are
stored uppercase. However, on most UNIX systems, people are used to
dealing with down-case names; therefore convert the strings to
lower-case before passing back to the user.
