e243721f22 doc: updated 3 man pages for 'LIBPROC_HIDE_KERNEL' var
This patch was prompted by Björn Fischer's merge #147
request referenced below. And since the library change
may impact all users, multiple man pages were updated.

[ and thanks to Björn for initiating this extension ]

9aa09d8862 library: Rename to libproc-2
What to call the new library?

Keep using libprocps wouldn't do, its a very different library from
the programs' point of view. It would also mean we could have some
clashes around the packages (two package names, same library name).

The ancient procps used libproc or libproc-a.b.c where a.b.c was the
package version. Kept the revision numbers down (it was always 0.0.0)
but the name of the library changed.

So if we use libproc-2 is there a clash with an ancient procps?
procps v 2.0.0 was around in 1999 so it was 22 years ago, also the
name of the library would have been libproc-2.0.0.so not libproc-2.so
so we're fine with that.

libproc-2 seems to fit, our second major re-work of the procps
library.

9c98179558 docs: expand 2 man pages 'Usage' to include VAL macros
Maybe, the biggest obstacle to successfully exploiting
this new library is after those `stacks' are returned.

Unless a user requests all available `items', there is
always a need to translate an actual enumerator into a
relative position within returned stack(s) of results.

So, this patch attempts to bridge that gap by adding a
brief explanation to the existing discussion in Usage.

[ along the way, 'Usage' & 'Caveats' were refactored ]

9b3436e0e4 docs: tweak both of those newly created man docs a tad
An important fact was omitted in the DEBUGGING section
for the two newest man documents. Users must utilize a
macro in the header files before verification happens.

So, this commit will sneak in such mention and in that
way reduce future liability if the feature won't work.

fc4fb85e7b docs: replace 'procps_pids' stuff with revised version
The original approach contained a fatal flaw. In order
to use those man pages, users would have been required
to already know how to use the library. Or alternately
one could randomly search each of them while trying to
ascertain which function call satisfies their need and
what exactly was the proper compliment/order required.

So, this revised approach tries to simplify things and
document only what is not apparent in the header file.
Along the way, the following assumptions were germane.

1) It is the kernel folks' job to document /proc files
not to mention fields within those files. And since we
don't yet know what some of those fields represent, we
shouldn't attempt to document any of those we do know.

2) Our header file serves as an essential reference in
successful exploitation of this new library interface.

3) The description represents functions as they appear
in the header itself making them immediately familiar.

4) Armed with our header file users can easily see the
self-documenting enumerators & structures. There isn't
a need to explain them yet again in this man document.

5) Contrary to man guidelines, we shouldn't list error
codes. Simple generic guidance serves everyone better.

The following references represent a history for those
man documents this new version is intended to replace.

eadb9db58f docs: update 'first cut' procps.3 with revised version
This represents the 'second cut' at providing a shared
man page that supports more than one newlib interface.

In this approach, the following assumptions were made:

1) It is the kernel folks' job to document /proc files
not to mention fields within those files. And since we
don't yet know what some of those fields represent, we
shouldn't attempt to document any of those we do know.

2) Our header files serve as an essential reference in
successful exploitation of the new library interfaces.

3) The description represents functions as they appear
in the header itself making them immediately familiar.

4) Some inconsistencies among the interfaces have been
handled more visually rather than in a narrative form.

5) Armed with our header file users can easily see the
self-documenting enumerators & structures. There isn't
a need to explain them yet again in this man document.

6) Contrary to man guidelines, we shouldn't list error
codes. Simple generic guidance serves everyone better.

9abf7d879d library: protect against large version numbers.
Linux release numbers are x.y.z we assumed but never protected
against x> 0x7fff and y,z > 0xff before.

Linux release in 1991, 1 major release per 6 years so we're fine
until 7452, unless they do way too many minor rels (max being 39)

6b5cb345c5 library: procps_uptime() return value is a status
procps_uptime, previously just plain uptime() used to put the
uptime (as a double) in the first argument and return uptime
(as an int).

It meant if you ran
 myuptime2 = procps_uptime(&myuptime1, NULL);
You might get different results for myuptime1 and myuptime2 because
they are different types.

Most library calls use the return value to return the status,
procps_uptime was in the middle.

Until now.

This function will return 0 on success. If you want (for whatever
reason) uptime as an int then cast it.

All of the procps binaries didn't use the return value for uptime
except ps which set a variable to it but never used it anywhere.
