remove double t from targeted, add missing r to arbitrary
And fix few more typos along the way in comments and man pages.

use emalloc and friends, add ktrace flag printing.

Provide symbolic printing of some keywords by capitalizing them.

Remove SCCS workaround. No binary change.

- dedup code
- add a safe_strftime() to handle error cases

Fix the column width calculation for the lstart column if an empty
column header is specified.

Add a fallback definition of LSDEAD in ps(1)

The symbol is no longer available in headers.

Requested by <mrg>

Make LSDEAD usage conditional

LSDEAD is not used since NetBSD-5.0 and will be gone.

The same conditional usage is already in ps.c in the same program.

Don't display l_wchan, either there is something in l_wmesg and we display
it, or there's nothing and we print "-".

use EXIT_FAILURE instead of 1

ps: Rename local routine name from uname to usrname

This removes symbol name routine clash with libc's uname(3).
This allows to build ps(1) against LLVM Sanitizers.

Handle functions that use the offset from either kinfo_proc2/kinfo_lwp properly.

provide a tree like display with -d, from FreeBSD

Calculate CPU usage (pcpu) once per process if it is required. This change
significantly improves performance for slow machines when output is sorted
by pcpu.

ok martin

for donlist{,_sysctl}:
- obtain log_ccpu = log(ccpu) rather than ccpu itself
- use common default values and warn users appropriately when errors occur
ok martin

Use l_wmesg if the string is not empty. Don't bother checking l_name for
nullness.

Use an enum type for PRINTMODE vs. WIDTHMODE. Compiler output diffs have
been checked.

Add an LTIME column that prints lwp cputime.

Use C89 function definitions

Remove unused variable.

When converting from pages to kilobytes, cast the return value of
getpagesize() to size_t. For some reason getpagesize() is defined to
return int, and several of the page counts we get come back from the
kernel as int32_t; in LP64 without the cast the byte count will be
computed in a 32-bit value and for large processes will overflow and
become negative... and then remain negative when divided by 1024 to
convert to kilobytes.

Fixes a problem I hit the other day where I saw negative RSS, which
turns out also to be PR 40642.

Note: other logic in here will break down when we first get >2TB
processes... and int32 page counts will break on >8TB processes. But
hopefully we won't see any of that for a few years yet.

fix previous.

Make printing of lwp flags similar to the process one, identifying (O)nproc
(K)ernel threads and scheduler (a)ctivations.

Do not check pcpu value against 100.0 but rather 99.95, to properly
deal with value rounding. From apb@.

Make %cpu drop the decimal part when reaching 100%, to stay in the 5
expected columns.
