Following positive feedback on tech-userlevel, move the sys_info

Sort options and their descriptions in man page and usage.

Update sys_info to 20170920

+ add a -d <destdir> option, which allows the versions of programs
in a directory tree rooted at "<destdir>" to be reported on, rather
than the programs and libraries rooted under /. This is useful, for
example, for finding out the versions of utilities and libraries
after a build.sh run:

Use Nm.

Fix xref.

Get rid of the arg sorting - it doesn't work properly, and makes it
impossible to support component names containing embedded \n's (the
similar embedded space problem would have been trivial to fix.)
Deleting the sorting makes those issues moot, the args are no longer
processed, hence can be anything.

An alternative would be to sort the results - but that would separate
the -v output from the real output (-v stuff is not rationally sortable)
and also makes it much more difficult to get the error code for an
unknown component (like one containing an embedded \n !) as the pipe
to strt that would be used would cause the while loop to run in a sub-shell
(effectively.)

Put back getopts - it is easier to get correct than hand rolled code.
Add -L and -P flags to allow the library/cmd search paths to be set.
Add support for getting vers info from sh, dhcpcd, and userland (/etc/release).
Stop abusing "sh -x" to support -v - do it properly. Get rid of the duplicate
list of components used when there are no args, instead make better use of sh
capabilities to just process everything. Better use of what sh can do for us
other places too. Add a (more or less random) set of libraries to include
in output when no args are given.

OK agc (well, earlier version...)

Changes to sys_info (20170821)

+ get rid of -a argument, which was superfluous since no arguments
means provide information on everything known

+ add the shell function to check for the path of a program. Taken
from pkgsrc bootstrap script, modified for return values, and "not
found" action

+ use this shell function for tcsh and unbound, both of which may not
exist on systems

+ go back to using standard shell construct for parsing options now,
since there is only 1 option with no optargs

+ from a suggestion from Paul Goyette, run the provided arguments
through sort | uniq

+ add sys_info itself to the list of programs to report

sys_info: Fix a minor typo from 2017, should make -d <directory path> work a bit better for X libraries

branches: 1.18.8;
show the verbose commands for bozohttpd and calendar too

And bump the version.

Also report versions of tcpdump, libpcap, and wpa_supplicant

Bump sys_info version to 20170928

Move back to a simple version string for sys_info. The way of using
CVS's $ Date $ expansion to calculate the date, whilst being more
accurate, runs into issues with reproducible builds, and alternate
repository software. Simplicity wins here.

Add yacc to the list of utilities to report on

Add a \ -- allows sys_info -v pkg_install to tell us who the version info
is obtained, rather than just how we go about printing the result.

add pkg_install to the list of programs reported

don't throw a warning if tcsh is not found in the path

Put back getopts - it is easier to get correct than hand rolled code.
Add -L and -P flags to allow the library/cmd search paths to be set.
Add support for getting vers info from sh, dhcpcd, and userland (/etc/release).

also add tzdata versioning information

restore martin's change for tcsh versioning which got lost in the last update

Use tcsh --version instead of an echo $version -- the old way did not
work for me (not quite sure why not).

Parse the arguments to sys_info(1) a bit differently, using getopts(1)

Thanks to Paul Goyette for the nudge

+ don't assume that tcsh is always installed, pointed out by jmcneill - thanks!

+ a "sys_info" invocation without any args is now the equivalent of sys_info -a,
just like pkg_info
