- Use seL4_Untyped_Describe to get an accurate view of each
UntypedMemory slab being managed; this makes mstats reflect
rootserver allocations.
- Track memory allocated before we run as "overhead" (was meant to
track fragmentation but was always zero).
- Add an "mdebug" command to describe each managed memory slab;
this is useful to see whether the kernel's view of memory use is
consistent with MemoryManager.

Enabling CONFIG_NOISY_UNTYPEDS causes the UntypedMemory slabs received
at boot to be logged to the console.

Running test_obj_alloc and similar (e.g. install+start+stop+uninstall)
on a release build yields kernel complaints about using a null
capability. Traced this down to delete_caps for ObjDesc's with count >
1. Checking the result from the syscall resolves things. Seems like an
optimizer bug.

- track CAmkES well-known name changes (e.g. RECV_CNODE -> MEMORT_RECV_CNODE)
- initialize the slot allocator for the component
- fix size_bytes to use the object count in its calculation
- add can_combine method to help optimize ObjDescBundle construction
- enhance ObjDescBundle:
- len, count, size_bytes, count_log2, maybe_combine_last
- move_objects_to_toplevel, move_objects_from_toplevel
- fmt (show SELF_CNODE & MEMORY_RECV_CNODE symbolically)
- add MmeCapAllocFailed
- add kata_object_alloc_in_toplevel & kata_object_free_toplevel
- add kata_object_alloc_in_cnode & kata_object_free_in_cnode
- add kata_frame_alloc_in_cnode
- avoid underflow in stats bookkeeping to not crash until we fix
the root cause

- kata-allocator, kata-kata-logger, kata-panic, and kata-slot-allocator
are now submodules of kata-os-common
- be more consistent on use stmts (and remove unneeded deps)
- cleanup various deps on kata-panic that no longer seem to be needed
(likely due to using resolver=2)

The MemoryManager service allocates & frees seL4 objects. Requests can be
batched. Capabilities to dynamically allocated objects are moved in CNode
containers attached to IPC requests.
Specific changes:
- Add new CAmkES MemoryManager component.
- Add api's for allocating & freeing singleton objects (e.g.
kata_cnode_alloc) and batches of objects (kata_object_alloc &
kata_object_free).
- Add support to kata-os-rootserver to hand-off UntypedMemory objects
just before terminating. The objects are placed directly in the
MemoryManager's top-level CNode and a BootInfo frame is constructed
that describes where the objects are.
- Switch the rootserver to kata-os-rootserver as the C version lacks
the UntypedMemory hand-off.
- Add test_bootinfo kata-shell command to dump the MemoryManager BootInfo
frame contents (broken for now because it directlry references the
shared page).
- Add test_obj_alloc kata-shell command that exercises the MemoryManager
singleton and batch api's
While here, did some cleanup of arg handling in kata-shell.
TODO: top-level object allocations use a simplistic capability allocator
TODO: move test_bootinfo to the MemoryManager and add an interface rpc
