The new library meminfo & vmstat modules use structure
names for their context which exactly mirror the names
of the very /proc/ files whose particulars they yield.
The one exception to this rule was the readstat module
whose struct was named statinfo yet the file was stat.
This commit simply renames that structure (only) so as
to hopefully establish such a naming convention as our
standard going forward. And, it's makes good symmetry.
[ this module's name itself is just perfect as it is ]

This patch mostly just eliminates darn tab characters.
Plus the library function declarations and definitions
have been standardized. Most visibly, the input params
now have all been indented on their own separate line.
The following names were changed to more closely match
meminfo.c or provide a certain symmetry. Unfortunately
that also impacted some other pgms which were updated.
. 'procps_stat_get' evolved into 'procps_stat_get_sys'
. 'procps_stat_info' is now known as 'procps_statinfo'
[and just a little trailing whitespace was eliminated]

Created new set of functions for meminfo related calls. Liked the
format of that better so changed vmstat around so the look similar.
Missed the makefile change for uptime so added it in now.
Use the standard libc declarations.
For protecting the headers for C++ procps used to have its
own defines, this change makes them use the standard libc ones.
getstat() -> procps_stat_*
vminfo() -> procps_vmstat_*
These two components of the library now use the newer version of
the API with less exposed global variables. The old methods are
there for now.

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.
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.
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.
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.
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.
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.
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.

'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.

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 >/dev/full ; echo $?

This commit brings the few remaining occurances
of kB, etc. into line with the IEC binary naming
standard.

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.
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.
