Minor enhancements, bug fixes, and man-page adjustments.

+ Make `sysrc -x foo' produce error status if foo is unset.
NB: Reported by lme (everything else ``while I'm at it'')
+ Remove mention of SYSRC_VERBOSE from `sysrc --help' output.
NB: False documentation leftover from an ancient precursor.
+ Make `sysrc -qc foo' work the same as `sysrc -ic foo' when foo is unset
NB: For syntax convenience (my fingers know `-q' more than `-i').
+ Update description of `-c' flag in help message/manual.
+ Update description of `-q' flag in help message/manual.
+ Make `sysrc -vc foo' work as documented in the manual
NB: Show message stating whether foo is currently set.
+ Make `sysrc -vc foo=1' work as documented in the manual
NB: Show message stating how value of foo would be changed (if at all).
+ Remove odd usage of parentheses in `-R dir' section of manual.
+ Clarify syntax section of manual w/respect to sysctl(8) similarities.
+ Add new/missing people to the `THANKS TO' section of the manual.

Merge head

IFC @264767

Merge head up to r262222 (last merge was incomplete).

MFC @ r259205 in preparation for some SVM updates. (for real this time)

Revert SVN r257830 -- that feature was annoying and was removed long ago.
Was a momentary memory lapse induced by old code that was lying in my ~/bin

Merge head r232040 through r258006.

Document SYSRC_VERBOSE enviroment variable in the manual.

Fix a bug with `-e' that broke sometime around when I added `-F'. Also,
revamp the `-e' output to truly be sh(1) compatible syntax (even if
passed in `-v' for verbose output).

Add a `-c' option for `check only' to determine if a value is set
(get command) or if the current value is the same as what is desired
(set command). In those cases, the return status is success.

Add a `-c' option for `check only' to determine if a value is set
(get command) or if the current value is the same as what is desired
(set command). In those cases, the return status is success.
Otherwise, if the variable is unset (get command) or set to a different
value that what is desired (set command), returns with error status.
This is useful for puppet integration as well as everyday scripting.

Add new `--version' long option for getting the version (good for
comparing against the ports revision).

Merge head r233826 through r256722.

Update sysrc(8) manual to coincide with r252797:

Do not inherit $SYSRC_VERBOSE from operating environment. The concern is
that when a user (such as myself) which has SYSRC_VERBOSE=1 in his/her
~/.bash_profile or such that when they are told to execute a command like:

hostname `sysrc -n hostname`

NOTE: To activate a recently configured hostname.

If $SYSRC_VERBOSE is set, then POLA is violated because the output of sysrc
is indirectly influenced (making for an inconsistent experience).
