dc072aced7 vmstat: Fixing format-security flaws
Previously the headers were printed directly without
the format specifier. That way is considered insecure
and leads to build errors with -Werror=format-security
flag set.

4fcd56bf58 vmstat: Support for timestamps with '-t' & fix for '-wd'
From now the vmstat can append a timestamp to each line in the
VMSTAT and DISKSTAT mode. You can achieve that with the '-t'
switch.
The '-w' switch now works in the DISKSTAT mode too.

1baf31be9b vmstat: wide output still not wide enough?
8 digits per memory column is apparently still too low
for systems with 128TB of RAM. Anyway, setting the limit
to 999TB (12 digits) must be sufficient for now as it
produces wide gaps on "regular" computers.
This commit also increases the number of digits per cpu
columns from 2 to 3 as some of them can hit the 100%
maximum in corner cases.

a8a4a4f595 vmstat: support for time stolen from virtual machines
Surprisingly the code for the 'st' column was added in the past,
but wasn't enabled. The vmstat manual already contains the 'st'
column and this commit finally enables the feature.

1b97942c8e vmstat: -w switch for wider output
This is a rework of the merge request #5 that unconditionally
forced the output to cross the 80 chars border.
With this commit users can switch to the wide output mode
with the -w option.

6437aa08d4 Update options to single strings
To assist the translators, each option is a separate string.
This means if we add/change/delete an option the remaining ones
will just keep working and only the impacted option needs some
translation work on it.

042776e04c configure: check for program_invocation_name
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.

00d7d4e37a vmstat si and so fields zero with -S mM 1
'si' and 'so' values depend on the result of the unitConvert
function where the output is a fixed-point size of kb_per_page
after the conversion. It gives 4 for kB units and 0 for MB units.
This also causes problems when switching between 'K' and 'k'
since the output value is 4 in both cases and the result for
'k' and 'K' then doesn't differ ... I swapped the conversion with
multiplication in order to make the number higher so it doesn't
lose precision. Since the unitConvert now accepts long instead
of int, I had to change the input type from int to long.

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.

032f2ed674 vmstat: validate numeric user input and allow infinte updates
The vmstat used ULONG_MAX as definition of infinite updates.  On a
computer with mighty uptime one will find that after 136 years
(assuming 1 second update interval) the vmstat exits, which is in
conflict with a promise of infinite.
