This command will analyze and print information about UUID's. The command
is based on libuuid/src/uuid_time.c but modified to use libsmartcol.

Docs: move option naming to howto-contribute.txt
Docs: update howto-usage-function.txt
Docs: add a comment for constants to boilerplate.c
include/c.h: add USAGE_COMMANDS and USAGE_COLUMNS
* 'usage-part1' of https://github.com/rudimeier/util-linux:
misc: no more errtryh()
mkfs.cramfs: add --help and --version
more: add --help and --version
whereis: add --help and --version
login: add --help and --version
fsck: add --help and --version
setarch: use errtryhelp()
dmesg: do not accept any non-option arguments
blkid: use errtryhelp instead of errtryh
misc: remove superfluous null pointer checks for optarg
uuidd: remove unused define
Nowadays all our regular commands have --help options.
test_uuidd does not use translations anyways.

Creating and naming options is not done when writing usage().
A contributor may not even read howto-usage-function.txt, but
they should read howto-contribute.txt. So move option naming
and change information there.

agetty refresh prompt (/etc/issue file etc.) when requested by inotify
or netlink. For this purpose we monitor some file descriptors by
select().
The terminal input file descriptor is switched to non-canonical mode before
select(). The goal is to be informed about user activity before
new-line. The FD is immediately switched back to canonical mode when
activity is detected. The side effect is that all not-read-yet chars in
the input buffer are lost ... so we need to call read() before switch
to canonical mode to save the chars.
The original implementation has been based on TIOCSTI ioctl. It
returns already read chars back to the terminal input buffer to make
them useful for canonical mode. The problem was race (agetty writes to
input buffer in the same time as user) and result was reordered chars
in login name... so useless.
This issue has been later fixed by extra buffer (commit
790119b885) for already read data. And
TIOCSTI ioctl has been removed. Unfortunately this solution is also
wrong, because the buffer is maintained only by agetty and
inaccessible for terminal when user edit (by DEL/CTRL^U) login name in
canonical mode.
The solution is simple -- just don't try to be smart and keep terminal
in canonical mode all time (so terminal controls DEL, CTRL^U, etc) and
flush input buffer (=discard unread data) and ask user for login name
again after prompt reload.
The agetty reload is very rarely situation and for user it's pretty
obvious that he has to type login name again (as all terminal has been
clear+redraw).

As discussed on the mailing list. We fix all places

These tools have special exit codes. They got changed mistakenly.

We can use errtryhelp() now and never print usage to stderr.
One may improve all these "bad usage" messages.
Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
Also we don't print the usage text on stderr anymore.
Note, the usage text could be improved, currently it
does not describe any options. I have only added a
pointer to the man page.

Also cleanup usage() function, never write usage to stderr.
FIXME:
- currently strtou32_or_err() exits with wrong exit code.
- option -C does not use a safe strto*_err function

As buf is passed as a signed char buffer in fwrite_hex, fprintf will
print every byte from 0x80 as a signed-extended int causing each of
these bytes to be printed as "\xffffff80" and such, which can be pretty
confusing. Force fprintf to use the argument as a char to make it print
only 2 digits, e.g. "\x80".

Structure dstring for label has 32 bytes, first byte is 8 (Compression ID),
last byte is 30 (count of 8bit characters in label). Therefore label is not
nul terminated and dstring parser needs to handle it (fixed in previous
commit).
$ dd if=/dev/zero of=udf-hdd-mkudffs-1.3-6.img bs=1M count=10
$ mkudffs -l AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA -b 512 udf-hdd-mkudffs-1.3-6.img
First byte of dstring is OSTA Compression ID and the last byte is length of
recorded bytes (including first byte). Last byte is not a part of recorded
characters, therefore it should not be treated as data to decode.

The current behavior is to report error and continue, it seems strange:
# blockdev --setro /dev/sdc
# wipefs -a /dev/sdc
wipefs: /dev/sdc: failed to erase xfs magic string at offset 0x00000000: Operation not permitted
/dev/sdc: 4 bytes were erased at offset 0x00000000 (xfs): 58 46 53 42
^^^^^^^^^^^

Switching between 'hardware clock' and 'RTC' is ambiguous.
RTC is used due to space constraints, so use it consistently.
