instead. Since we're little endian, we can get away with it. Also,
since the counters in quesitons would require billions of iops for
tens of billions of seconds to overflow, and since such data rates are
unlikely for people using i386 for a while, that's OK. The fastest
cards today can't do even a million IOPs.

it in human readable form. Include a pointer to the public spec that
was followed to implement this in the code. Samsung also implements
page 0xca on some of their drives, but the format is slighly
different, so the code skips printing zero keys. Samsung's log page
has additional, unknown data after the end of Intel defined data which
isn't displayed.

number is printed, even though you'd need like a billion IOPs for a 10
billion seconds to overflow the 64-bit counters (~300 years).

doesn't make them invalid and future versions of the standard may
define then.

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.

* 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.

This includes pretty printers for all of the standard NVMe log pages
(Error, SMART/Health, Firmware), as well as hex output for non-standard
or vendor-specific log pages.
