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).

arch: arm64: detect kernel stack overflow condition
...
Currently, when a kernel stack overflow occures, the exception handler
blindly attempts to write the current context to the stack. If the SP
isn't valid this causes another fault, and so on - locking up the
system.
This commit re-arranges the stack layout, performs SP validation before
usage and switches to an emergency stack when SP isn't valid. This
allows the handler to run and panic gracefully.

libkernel: CpuOps: add 'static trait bound

The CpuOps trait should never hold a reference to any other object. In
fact, it should be a singleton object which is constructed at kernel
boot and live for the entire lifetime of the system. Therefore, it's
safe to add the `'static` trait bound.

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.
