Determine if a device supports "Extended" or "Separate" metadata, and
what the current metadata setting is (None, Extended, Separate)
Also determine if the device supports:
- Sanitize Crypto Erase
- Sanitize Block Erase
- Sanitize Overwrite

nvmecontrol tries to upload firmware in chunks as large as it thinks
the device permits. It fails to take into account the FWUG value used
by some drives to advertise the size and alignment limits for firmware
chunks.
- Use the firwmare update granularity value from the
- If the granularity is not reported or not restricted, fall back to
the previously existing logic that calculates the max transfer
size based on MDTS.
- Add firmware update granularity to the identify-controller output.

The Host Buffer feature (NVMe 1.4 section 89) allows for the NVMe card
request the host provide it buffer for lookaside tables and maybe
other things. Report the card's minimum and preferred sizes with
nvmecontrol/camcontrol identify.
It allows to delete all user data from NVM subsystem in one of 3 methods.
It is a close equivalent of SCSI SANITIZE command of `camcontrol sanitize`,
so I tried to keep arguments as close as possible.
While there, fix supported sanitize methods reporting in `identify`.

While very useful by itself, it also makes `nvmecontrol` not depend on
hardcoded device names parsing, that in its turn makes simple to take
nvdX (and potentially any other) device names as arguments.
Also added IOCTL bypass from nvdX to respective nvmeYnsZ makes them
interchangeable for management purposes.

This adds several previously missed but important subcommands to list
namespaces and controllers. It also fixes few previously added but
just found with real testing to be broken subcommands.
Also while there, add possibility to explicitly specify nsid for
`nvmecontrol identify` subcommand. It may be useful to specify nsids
not having own devices, for example 0xffffffff, or just newly created
ones.

Rename print_controller to nvme_print_controller. Put it in its
own file for easy inclusion. Move util.c to be nc_util.c to not
conflict with camcontrol. add nvecontrol_ext.h to define shared
interfaces.
