173d5214db ps: add lots of sorting functions
Use NULL in format_array to indicate that the print function shall be
used also for sorting. Change sr_nop() to NULL for all fields which
don't use pr_nop() for printing.

Before the commit (note that '--sort label' has no effect: the rows
are not sorted according to label field):
$ ps -A -o command,label --sort label | grep /lib/systemd
/lib/systemd/systemd-journa system_u:system_r:syslogd_t:s0
/lib/systemd/systemd-udevd  system_u:system_r:udev_t:s0-s0:c0.c1023
/lib/systemd/systemd-networ system_u:system_r:systemd_networkd_t:s0
/lib/systemd/systemd-resolv system_u:system_r:systemd_resolved_t:s0
/lib/systemd/systemd-timesy system_u:system_r:ntpd_t:s0
/lib/systemd/systemd-logind system_u:system_r:systemd_logind_t:s0
/lib/systemd/systemd --user user_u:user_r:user_t:s0
/lib/systemd/systemd --user root:sysadm_r:sysadm_t:s0-s0:c0.c1023
grep /lib/systemd           user_u:user_r:user_t:s0

After the commit, '--sort label' works and the output is sorted:
$ ps -A -o command,label --sort label | grep /lib/systemd
/lib/systemd/systemd --user root:sysadm_r:sysadm_t:s0-s0:c0.c1023
/lib/systemd/systemd-timesy system_u:system_r:ntpd_t:s0
/lib/systemd/systemd-journa system_u:system_r:syslogd_t:s0
/lib/systemd/systemd-logind system_u:system_r:systemd_logind_t:s0
/lib/systemd/systemd-networ system_u:system_r:systemd_networkd_t:s0
/lib/systemd/systemd-resolv system_u:system_r:systemd_resolved_t:s0
/lib/systemd/systemd-udevd  system_u:system_r:udev_t:s0-s0:c0.c1023
/lib/systemd/systemd --user user_u:user_r:user_t:s0
grep /lib/systemd           user_u:user_r:user_t:s0

cde22815af ps/sortformat.c: Catch negative width in format_parse().
The existing strspn() check guarantees that the string contains no '-'

db00f54f4a ps/sortformat.c: Double-check chars in verify_short_sort().
To avoid an out-of-bounds access at checkoff[tmp]. The strspn() at the
beginning of the function protects against it already, but double-check
this in case of some future change.

b2f49b105d Closes: #9 ps: Remove Unix98 output limitations
ps previously followed the Unix98 standard when it comes to
user-defined output, sometimes. This meant you could have
user output format with a header that included commas and
equals signs. It was dependent on if ps thought you wanted
sysv or bsd format and THAT was dependent on things in previous
options.

It was very confusing to a user because
 ps p $$ -o pid=,comm=
gave you a two-column output but
 ps -p $$ -o pid=,comm=
would give you a one column output with the header ",comm="

The -p versus p means (to ps) you want sysv or bsd parsing.
Unix98 standard or not, this is plainly just silly.

The commit removes any of the quirks Unix98 has with user defined
output.  If you really wanted a ps header with commas in the output,
today isn't your day.

ce61089059 docs: clarification to license headers in files
Add license header to all files.  The summary of licensing is below,
taken from Craig Small's email which is referred in commit message
tail.

sysctl and pgrep are GPL 2+
The rest is LGPL 2.1+

79ceb30b5c ps: unify cases and remove trailing dots in messages
Strings with lower caps & no trailing dots have greater change to
have multiple occurences, meaning less effort for translators, than
strings with them.

71b72b36ce ps: minor reformatting and trailing whitespace elimination
This patch mostly reorganizes include files and eliminates
some useless trailing whitespace.

It also adopts the standard procps-ng unconditional approach
to nls initialization.

2865ded64e Removed xalloc type functions from library
These xalloc functions are a private function for the library. If using
programs need them, then they should make their own error reporting or
use a common file.

229be7b160 ps: exploit enhanced library memory allocation provisions
There were numerous ps memory allocation inconsistencies.
Some were checked for failure and others were not.

The program was modified to utilize the library memory
rouines which are consistent in dealing with errors.

(a few changes simply removed trailing whitespace)
