Several parameters for zoned devices are missing from lsblk's columns. This
series introduces them as following.

 Column Name      Description             Sysfs path
 ---------------------------------------------------------------------
 ZONE-SIZE        zone size               queue/chunk_sectors
 ZONE-WGRAN       zone write granularity  queue/zone_write_granularity
 ZONE-APPEND      zone append max bytes   queue/zone_append_max_bytes
 ZONES-NR         number of zones         queue/nr_zones
 ZONES-OMAX       max open zones          queue/max_open_zones
 ZONES-AMAX       max active zones        queue/max_active_zones

Sample output:

$ lsblk -o NAME,ZONED,ZONE-SIZE,ZONE-WGRAN,ZONE-APPEND,ZONES-NR,ZONES-OMAX,ZONES-AMAX -i

Factor out a new function device_read_bytes() to read a sysfs path as bytes
for a preparation for the next commit and to reduce the code duplication.

What about to add all the columns to "--zoned" output too? 

We do not keep backward compatibility for set of columns in outputs
like --zoned, so it's open for changes. I guess we can use --zoned as
a generic option for all zoned stuff and not for a model only.

It would be nice to have shorter column names, but I do not have any
sane suggestion (Z-SIZE or Z-APPEND seems strange).

Nice idea. I'll add a patch for that.

Hmm, considering we already have DISC-{ALN,GRAN,MAX,ZERO}, how about
ZONE-{SZ,GRAN,APP,NR,OMAX,AMAX}?

That work for me. One nit though: having the ZONE-NR and ZONE-SZ columns come
first would be nice since these are the 2 most important properties that users
will look at before digging into details of other limits.

I also wonder if we want to add max_zone_append_bytes here... We should only if
attributes such as max_sectors etc are listed too (I have not checked).
