Add signature for module Crc; hide initial CRC value

In all uses we were passing in the initial CRC constant, so
there was no reason to actually expose it in the interface.

Now we just have:

val crc: string -> int32

Make Constants.fmtt_magic into a static string

Verified by utop (TM):

utop # Stringext.String.implode (List.map Char.chr [0o040;0o114;0o126;0o115;0o062;0o040;0o170;0o133;0o065;0o101;0o045;0o162;0o060;0o116;0o052;0o076]) = " LVM2 x[5A%r0N*>"
;;
- : bool = true

tags: simplify interface

Rather than throwing an exception when we encounter an invalid tag,
we simply treat the unrecognised characters as if they were '_'.

Rename Tag.string_of -> Tag.to_string, to make this more like the
stdlib (Int64 etc)

Remove all unnecessary functions from the Tag interface.

allocator: hook up the test case, begin to narrow the interface

Unfortunately some of the allocator tests seem to fail, but the process
exits with 0.

Note also: most of the allocator interface is only used by the test
case. There's a risk the interface we're actually using is less well
tested.
