script from othersrc to usr.bin/sys_info
The sys_info script is a small script which will show the version
information for installed utilities. It also works on the kernel, and
on most libraries.
Its use is as follow:

The -a option can be given to the script to print out the information
on all known components.
The sys_info script also works on libraries, returning their
"versions" as given by the shared object version numbers.

realpath(3) is expensive, and meta mode at least uses it extensively.
We use cached_realpath() to save the result of successful calls to
realpath(3) in a private variable context.
This improves the worst case performance (eg examining libc with
nothing to do) by a factor of 4.

Both meta_create() and meta_oodate() now share meta_needed()
to indicate if a .meta file is needed.
This allows for deciding that missing .meta file is cause of out-of-date.
The new knob 'missing-meta' controlls this, and is off by default
since the side effect files of generators like yacc will typically need
.NOMETA to avoid problems.
This however makes it much easier for folk to switch back and forth
with meta mode (eg. FreeBSD's normal build can leverage meta mode for
improved reliablility without need to clean).
Also if .MAKE.MODE does not contain 'nofilemon', the knob
'missing-filemon' allows control as to whether missing filemon data
should cause the target to be out-of-date.
Again off by default.
setting \n as the record delimited using a numeric value rather than literal
\n - and to not incorrectly turn \n into a field separator if -R is used to
make some other char the record separator (\n becomes a field separator in
that case as long as the field separator remains "white space" but should not
be in any other case - unless set explicitly of course.)
Plus more cosmetic changes - the man page and usage are updated to make it
more clear that the 2 (or 1) params to -k are not fields (field1 and field2)
but specifiers of the beginning and end of one key field. There was an
unused 'x' option in the GETOPTS string. The usage message is reformatted
to display properly on both 80 col and > 80 col displays (on < 80 it will
still probably look pretty ugly ... perhaps not quite so bad though), and
is also updated to show the different usage for the -c case (and -C) from the
others (only 1 file permitted) - the man page synopsis has a similar update.
Using more than one of -c -C or -m generates a usage message rather than
just ignoring the -m as it did before (there was no -C before of course).
Aside from the bug fix to the interaction between -R and -t, there are no
changes that affect the way anything is sorted (or read, or written).
Discussed on tech-userlevel earlier this week.

XXX There are still some other warnings remaining to be resolved.
Fixes PR bin/48195 although we really should go back someday and fix
this correctly (by replacing all uses of mktemp(3)!)
If -B compatMake will be true and should be honored.
If -j forceJobs will be true and the command line supplied .MAKE.JOBS
should be respected - for consistency with other usage.
By this change, nexthop caches (IP-MAC address pair) are not stored
in the routing table anymore. Instead nexthop caches are stored in
each network interface; we already have lltable/llentry data structure
for this purpose. This change also obsoletes the concept of cloning/cloned
routes. Cloned routes no longer exist while cloning routes still exist
with renamed to connected routes.
Noticeable changes are:
- Nexthop caches aren't listed in route show/netstat -r
- sysctl(NET_RT_DUMP) doesn't return them
- If RTF_LLDATA is specified, it returns nexthop caches
- Several definitions of routing flags and messages are removed
- RTF_CLONING, RTF_XRESOLVE, RTF_LLINFO, RTF_CLONED and RTM_RESOLVE
- RTF_CONNECTED is added
- It has the same value of RTF_CLONING for backward compatibility
- route's -xresolve, -[no]cloned and -llinfo options are removed
- -[no]cloning remains because it seems there are users
- -[no]connected is introduced and recommended
to be used instead of -[no]cloning
- route show/netstat -r drops some flags
- 'L' and 'c' are not seen anymore
- 'C' now indicates a connected route
- Gateway value of a route of an interface address is now not
a L2 address but "link#N" like a connected (cloning) route
- Proxy ARP: "arp -s ... pub" doesn't create a route
You can know details of behavior changes by seeing diffs under tests/.
Proposed on tech-net and tech-kern:
http://mail-index.netbsd.org/tech-net/2016/03/11/msg005701.html
Prevents an extra "Bad file descriptor" message when trying to hexdump
a single nonexistent file.
The intended behavior seems to have been to read from stdin if there
was one filename given and it wasn't valid. But this seems like a bad
idea, so prevent that case instead of hacking it up so it works.
Like .sinclude missing file will be ignored.
Like .depend stale dependencies will be ignored.
Allows better implementation of auto depend.

Requested by: Bryan Drewery at FreeBSD.
Also handle negative numbers better in general (don't randomly drop
the sign in a number of cases) and don't choke on exponents > 9.
This commit alters the meaning of a few previously valid but marginal
inputs (e.g. "3 foot-5 pound" is now treated as "3*-5 foot-pound"
rather than "3*5 foot-pound"; if you want the latter insert another
space) but corrects obviously wrong handling of many more.
In the bulk of the output making this change would require reworking a
bunch of the internals to allow spaces in type names, which at the
moment doesn't seem worthwhile.
- include the pattern in the error printing of regex
- handle 3 argument and empty patterns the gnu way
- add support for freezing and thawing state (not working yet)
- handle macros > $9
- handle character remapping the the gnu way.
Add a shortcut for the "fake freeze" files to not expand include macros
during thawing.
