[PATCH nbdinfo proposal] info: Add a --map option for displaying allocation metadata
This is a rough-and-ready implementation of nbdinfo --map option, to
display the allocation and other metadata of NBD exports. I only
tested it lightly against nbdkit. It needs at least some tests.
Command like these should work:
nbdinfo --map nbd://localhost
nbdinfo --map=qemu:dirty-bitmap nbd://localhost

Should we favor the use of LIBNBD_CONTEXT_BASE_ALLOCATION instead of
open-coding this?

[PATCH libnbd 0/5] info: --map: Coalesce adjacent extents of the same type.
This adds coalescing of adjacent extents of the same type, as
mentioned by Eric Blake in the commit message here:
https://github.com/libguestfs/libnbd/commit/46072f6611f80245846a445766da071e457b00cd
The patch series is rather long because it detours through adding the
<vector.h> library from nbdkit into libnbd and replacing ad hoc uses
of realloc, char ** etc in various places.
