e01765d30b sysctl: deprecate parameters
According to arp(7) manual page base_reachable_time and retrans_time
are obsolete since kernel 2.6.12. Based on that the print all listing
will not show these two parameters, and attempt to set them will fail.

79ceb30b5c ps: unify cases and remove trailing dots in messages
Strings with lower caps & no trailing dots have greater change to
have multiple occurences, meaning less effort for translators, than
strings with them.

fb11e1fe0a Changed the err and warns to macros
err and warn are BSD format but they are not recommended by library
developers.  However their consiseness is useful!

The solution is to use some macros that create xerr etc which then
just map to the error() function.  The next problem is error() uses
program_invocation_name so we set this to program_invovation_short_name

This is a global set but seems to be the convention (or at least errors
are on the short name only) used everywhere else.

a10282422b sysctl: enable pattern matching with path
Pattern matching support in `sysctl: implement --pattern option'
commit did not work when variable path was defined, for example

$ sysctl net.ipv4 -r arp.ignore

gave no output. Reason being was tht the pattern was matched agains
the specified argument and not the output variable list.

8795154eac sysctl: warn when separators are repeated
For some reason sysctl earlier allowed quite strange separators.

% sysctl kernel./.pty.nr
kernel./.pty.nr = 6
% sysctl kernel///pty//////////nr
kernel...pty..........nr = 6

This commit does not disallow that sort of constructs, but will warn
about them. In future disallowing these might be reasonable thing to
do.

% sysctl kernel./.pty.nr
sysctl: separators should not be repeated: ./.pty.nr
kernel./.pty.nr = 6

100959274c sysctl: add --system switch
instead of requiring distributions to construct a loop around sysctl
in boot scripts just scan a set of default directories if the --system
switch is used.

Config files are applied in alphabetic order of their base name.
Each base name is only applied once according to the directory
preference. /etc/sysctl.conf is always applied last.

81df8e2630 sysctl: options handling & usage output
The sysctl now uses getopt_long and has help screen which be user
friendly. Rest of the modernization is left later, since this is
a command is used in scripts, and changing for instance error
printing to use warn & warnx could break stuff.
