e8f25c6266 Define constants for the lengths of the serial number, model number 
and firmware revision in the controller's identify structure.

Also modify consumers of these fields to ensure they only use the
specified number of bytes for their respective fields.

08c29873bf Ensure controller or namespace node name is specified before trying to 
access it.

While here, also fix the identify usage message to show the -v and -x
parameters.

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.

d2cdb28b6f Ensure that a device node is specified when invoking the identify or reset 
commands.

Also improve the checking of device node names, so that better error
messages are displayed when incorrect names are specified.

6420873cd6 Create #defines for NVME_CTRLR_PREFIX and NVME_NS_PREFIX for the "nvme" 
and "ns" strings, rather than hardcoding the string values throughout the
nvmecontrol code base.
