If you mark a column with TT_FL_NOEXTREMES flag then extremely
large fields will no have effect to column width. Foe example:
without the TT_FL_NOEXTREMES flag for the 'AAA' column:
AAA BBB CCC DDD
aa bbb ccc ddd
aaaaaaaaaaa bb ccc ddd
aa bb ccc ddd
aa bb ccc ddd
with the flags:
AAA BBB CCC DDD
aa bbb ccc dddddddddd
aaaaaaaaaaa
bb ccc dddddddd
aa bb ccc dddddd
aa bb ccc ddddddddd

We use ARRAY_SIZE() instead to define the amount of available columns.

The lsblk depends on /sys/dev/block/ symlinks, which appeared in
kernel 2.6.27. Users with old, or non-sysfs configured, kernel
got ealier message
lsblk: md0: failed to initialize sysfs handler
lsblk: xvda: failed to initialize sysfs handler
[...]
that I found a little too difficult to understand. This patch will
change the message to
lsblk: failed to access sysfs directory: /sys/dev/block: No such file or directory
and informs in manual page what could be reason to that.

If lsblk runing on system where many devices appears and disappears
during lsblk run, lsblk should not fail or crash but just ignore
disappeared device.
Let's detect context initialization failures and skip device
instead of failing.
Also fix possible dereferencing of NULL parent pointer and
properly handle some error paths.

for device-mapper devices running or suspended.

Use atol() instead of atoi() when extracting discard_max_bytes.
Only print discard_alignment and discard_zeroes_data if the device
supports discard. This prevents printing of undefined values with older
kernels.

I got tired of poking around in sysfs to find the discard topology.
Here's a patch against lsblk that adds a -D option to present this
information in a human-readable form:
NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO
sda 0 0B 0B 0
└─sda1 0 0B 0B 0
sdb 0 512B 2G 1

Solaris lacks err, errx, warn and warnx. This also means the err.h header
doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.
