38441bd9a9 Add message when nvd disks are attached and detached.
As part of this commit, add an nvme_strvis() function which borrows
heavily from cam_strvis().  This will allow stripping of
leading/trailing whitespace and also handle unprintable characters
in model/serial numbers.  This function goes into a new nvme_util.c
file which is used by both the driver and nvmecontrol.

2fb37e8f1a Fix nvme(4) and nvd(4) to support non 512-byte sector sizes.
Recent testing with QEMU that has variable sector size support for
NVMe uncovered some of these issues.  Chatham prototype boards supported
only 512 byte sectors.

2528d6a326 Send per-namespace logpage commands to the controller devnode, so they
are processed as admin commands, not I/O commands.

As part of this change, pull out the code for parsing a namespace node
string into a separate function, since it is used for both identify and
logpage commands.

821ef73ca6 Incorporate feedback from bde@ based on r252672 changes:
* Use 0/1 instead of sysexits.  Man pages are confusing on this topic,
  but 0/1 is sufficient for nvmecontrol.
* Use err function family where possible instead of fprintf/exit.
* Fix some typing errors.
* Clean up some error message inconsistencies.

49fac6101d Add firmware replacement and activation support to nvmecontrol(8) through
a new firmware command.

NVMe controllers may support up to 7 firmware slots for storing of
different firmware revisions.  This new firmware command supports
firmware replacement (i.e. firmware download) with or without immediate
activation, or activation of a previously stored firmware image.  It
also supports selection of the firmware slot during replacement
operations, using IDENTIFY information from the controller to
check that the specified slot is valid.

Newly activated firmware does not take effect until the new controller
reset, either via a reboot or separate 'nvmecontrol reset' command to the
same controller.

b846efd7ec Add controller reset capability to nvme(4) and ability to explicitly
invoke it from nvmecontrol(8).

Controller reset will be performed in cases where I/O are repeatedly
timing out, the controller reports an unrecoverable condition, or
when explicitly requested via IOCTL or an nvme consumer.  Since the
controller may be in such a state where it cannot even process queue
deletion requests, we will perform a controller reset without trying
to clean up anything on the controller first.
