The length option is used to specify the number of zones to
operate on. To be more consistent with other tools, have this
option use a number of sectors and introduce the --count option
to allow users to specify a number of zones.
The --count and --length options cannot be used together on
the command line.

Add "0x" to the zone start, length and write pointer print
to make it always clear that the values are Hexadecimal.
Also update the zone condition string and associated comments
to match more closely the wording in the standard document.
The man page is also updated to match the new wording.

Report all zones of the block device when length is not specified
on the command line. To do this, introduce an inner loop in
blkzone_report to repeatedly issue report zone ioctl to the
device.

If length is 0, operate on all zones starting from offset.
This also fix the maximum length calculation from offset.
