FreeBSD has no good way of finding the Hertz value. ELF notes don't
work, you can't find it in a function and even asm/params.h does
not have it. Lucky for us, it is always 100.
Based upon Debian patch patch sysinfo_kfreebsd_hertz by Petr Salinger
Bug-Debian: http://bugs.debian.org/460331
Caution, 460331 has lots of overlapping bugs all around the Hertz
problem across many arches.
Suppresses a message about elf notes not found on non-Linux systems.
kFreeBSD systems, for one, don't have this so the message appears
every time you run a procps program otherwise.

Documentation changes
ps.1
. added supgid and supgrp
top.1
. added supgid and supgrp
. addition of above required renumbering
many fields in section 3a. DESCRIPTIONS
This source patch addresses the following:
Conceivable Buglets Avoided
. added sanity checks for previous assumptions re: pid size, num cpus
. changed response for rcfile errors to fatal, vs. silent default
Enhancements
. reorganized WIN_t struct for reduced padding and better readability
. generalized code for multiple var-width cols (divorced from pflags)
. absorbed jan gorig's cgroup patch, with attribution
Cosmetic
. reduced numerous #ifdef directives, especially in calibrate_fields
The documentation portion of the patch addresses the following:
README.top
. corrected a minor typo
. updated to reflect current patch level
top.1
. fixed potentially misinterpreted Me/ME strings
. added '.Bd -literal' directives for indented fixed-width font
. some comments changed from \# to .\" to avoid man2html problems
The source portion of the patch addresses the following:
Buglets
. header/task output length now consistent
. fixed 2 obscure horizontal scrolling bugs
. fixed potential bug regarding 'help' and 'current' window
. messages and prompts are now also sensitive to terminal width
. normalized buffer names/sizes now accommodate any SCREENMAX changes
Features
. made %CPU and 'i' mode handling more efficient
. for input the Up/Dn arrows keys act as alternatives to Ins/Del keys
. an optional USE_X_COLHDR define eliminates ALL 'x' toggle overhead
. an optional ZAP_SUSEONLY define was added for Werner's modifications
Cosmetic
