Revert r295169 and switch `\ ' to `" "'

For +=/-=, add . and / to convenience characters

sysrc(8) supports key+=value and key-=value, but can be told what the
delimiter is by being passed as char1 (e.g., "sysrc key+=",value" to use a
comma as the delimiter instead of space). For convenience, if the first char
is alpha-numeric, it is assumed you wanted whitespace as the delimiter.

However, if you naively (as I just did) execute:
sysrc rc_conf_files+=/etc/rc.conf.other
the result is unexpected.

This commit makes `.' and `/' in-addition to alpha-numeric first-characters
to cause the default of whitespace to be used as the delimiter. This also
means that you can no longer use these as a delimiter.

Replace (Qo \ Qc) with (Qo (space) Qc)

When using col(1) piped to vim(1) as pager for man(1), the former sequence
of (Qo \ Qc) renders as "" without the space. Replace with (Qo (space) Qc)
which renders properly in more (all?) pagers.

Add sysrc(8) support for "rc.conf.d" file(s) when given "-s name" to
indicate service(8) script. While here, add "-l" option for listing the
set of configuration file(s) considered (in order; separated by space).
Also add "-L" for exploring all configuration files and "-E" to omit
files that don't exist from operations.

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.

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

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.
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).

Update release info.

Update copyright/date on the back of r252798.

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).

Remove whitespace at EOL

Import sysutils/sysrc from the ports tree (current version 5.1). Importing
disconnected under the WITH_BSDCONFIG flag (a good idea since this version of
sysrc(8) indeed requires the `sysrc.subr' module installed by bsdconfig(8)).

Multiple reasons sysrc should not simply continue to live in ports. The most
important being that it is tightly coupled with the base.
