free, slabtop and uptime would happily take extra command line
arguments and doing nothing about them. The programs now check
optind after option processing and will give you usage screen
if there is anything extra.

This patch will fix a fencepost error that has existed
since at least 2004, the result of which was to always
completely ignore that last merged / sorted slab node.
[ Of course, little harm was done since output would ]
[ have been limited to a terminal's height. Thus, it ]
[ would have required a huge display before noticed. ]
[ But, now that the run once switch shows everything ]
[ such an omission would become really unforgivable. ]

It doesn't make sense to restrict the number of output
lines to the total of terminal rows when using the run
once command line switch. And, in fact, that's how the
newlib version of slabtop works. Everything is output.
So, this commit places both versions on equal footing.
[ it was even worse if the switch was used in a pipe ]
[ since only 23 lines would have then been displayed ]

When the command is executed in one shot mode (-o) with stdin
being something other than a terminal, the tcgetattr() call
would fail, and generate an error message. e.g.:
slabtop: terminal setting retrieval: Inappropriate ioctl for device
Active / Total Objects (% used) : 905319 / 915886 (98.8%)

Minor fixes that the translator (Yuri) has found in some of the
strings. You only know how many typos and thinkos you have when
someone is trying to translate it.

To assist translators, the help lines are split so that each translation
chunk has one option. This gives bonus of if we add or change an option,
only that option remains untranslated rather than the entire help block.

An earlier commit attempted to cleanse our environment
of all useless trailing whitespace. But the effort did
not catch 'empty' lines with a single space before ^J.
This commit hopefully finishes off the earlier effort.
In the meantime, let's pray that contributors' editors
are configured so that such wasted crap is disallowed!

For portabiliy, check for program_invocation_name during configure and
define HAVE_PROGRAM_INVOCATION_NAME accordingly. Use of this symbol is
now enclosed with the appropriate #ifdef block.
The symbol program_invocation_name is only used for error message
handling using error(), so it's safe to omit this if it is not
available.
If stream status is not checked at the end of execution below problem
would not report error, or non-zero exit code. The uptime is just an
example same was true with all commands of the project.
$ uptime >&- ; echo $?
uptime: write error: Bad file descriptor
1
$ uptime >/dev/full ; echo $?
uptime: write error: No space left on device

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.
This commit fixes also peculiar behavior of
$ slabtop -d 0
which did not make sense. The fix is to disallow anything else but
positive integers, which includes zero as is is not positive (or
negative) number.
