1aa8b16441 library: eliminated the questionable 'procps.h' header
There was a time when that procps.h file served a more
traditional role. Prior to the commit referenced below
it held just macros plus manifest constants. But, with
that change, such items were replaced with a series of
includes embracing all the library exported functions.

That approach was known to disguise errors which would
have otherwise yielded a compiler warning. And without
such a warning, there was no way to address the error.

So this patch will trade the all inclusive header file
approach for individual includes only where necessary.

Reference(s):
. April 2016, procps.h header file revamped
commit ccb6ae8de1
. Sept 2018, top abandoned use of procps.h
commit a6dfc2382e

eaec2d0977 0121-w: Clamp maxcmd to the MIN/MAX_CMD_WIDTH range.
The current checks allow out-of-range values (for example, if
getenv/atoi returns ~-2GB, maxcmd becomes ~+2GB after the subtraction).
This is not a security problem, none of this is under an attacker's
control.

105058ae2d related: fix inconsistencies in result type references
This patch is a response to errors found in those type
references now that our library allows for validation.

In two cases, former assignments to a result structure
could no longer employ that VAL macro if validation is
active. Thus, direct reference to some stack was used.

For the record, those instances were to be found here:
. ps - uses PIDS_extra to store the cooked pcpu values
. top - uses PIDS_extra to store the forest view level

e0515e23e7 related: respond to VAL macro addition of context parm
Since the VAL macro now requires a 4th parameter, this
commit simply adds the 'info' context structure to it.

In some cases, that context structure needed to become
global, since it was referenced in multiple functions.

612f36189e related: change for lost 'PROCPS_' enumerator prefixes
With this patch we've completed a progression toward a
standard approach to naming conventions which follows:

* Only functions will begin with that 'procps_' prefix
. ........................................... examples
. procps_vmstat_get ()
. procps_diskstats_select ()
- ----------------------------------------------------

* Exposed structures begin with the module/header name
. ........................................... examples
. struct pids_info
. struct stat_reaped
- ----------------------------------------------------

* Item enumerators begin like structs, but capitalized
. ........................................... examples
. VMSTAT_COMPACT_FAIL
. MEMINFO_DELTA_ACTIVE

[ slabinfo varies slightly due to some item variants ]
. SLABINFO_extra
. SLABS_SIZE_ACTIVE
. SLABNODE_OBJS_PER_SLAB
[ could cure with a prefix of SLABINFO, but too long ]
- ----------------------------------------------------

* Other enumerators work exactly like item enumerators
. ........................................... examples
. PIDS_SORT_ASCEND
. STAT_REAP_CPUS_AND_NODES
- ----------------------------------------------------

* Macros and constants begin just like the enumerators
. ........................................... examples
. #define SLABINFO_GET
. #define DISKSTATS_TYPE_DISK
- ----------------------------------------------------

ccb6ae8de1 library: cleanup of library includes
The includes used to define a lot of things a library include
should not. It was also a bit messy what was exposed in the library
and what was not.

get_pid_digits -> procps_pid_length and exported correctly

MALLOC attribute move into relevant .c files
NORETURN attribute moved to relevant .c, not used in library
PURE attribute removed, it wasn't used
KLONG/KLF/STRTOUKL were fixed for long, so now just use long

HIDDEN attribute removed. It was for 3 functions. The PROCPS_EXPORT
seems to do the same (opposite) thing.

likely/unlikely removed from most places, its highly debateable
this does anything useful as CPUs have gotten smarter about branches.

Re-arranged the includes, ALL external programs should just #include
<proc/procps.h> then proc/procps.h includes headers for files that
have exported functions. procps.h and the headers it includes should
not use items that are not exportable (e.g. hidden functions or
macros) they go in procps-private.h

7b08ad19cc w: Adjust command width
w would error out if the window size was smaller than 71 or some
other fields through environment grew too big. The code was a little
convoluted as well. The minimum length for command was 3, which is
pretty useless.

This change does the following:
 w doesn't care by default the window size
 w will adjust the command length up and down, to a minimum of 7
characters.
 if the fields don't fit, w will line-wrap each line.

The idea being its better the line-wrap than it is to error out.

This commit is an outgrowth of the research into a bug
involving the recently added enum 'PROCPS_PIDS_extra'.

The WHAT portion of output is being padded with spaces
since the printf field width format specifier was used
in combination with a precision specifier. This commit

7888f6a679 miscellaneous: clean up trailing whitespace once again
An earlier commit attempted to cleanse our environment

The symbol program_invocation_name is only used for error message

The entire tree's polluted with inappropriate trailing
whitespace. This commit rids our environment of all of
those useless keystrokes. Unfortunately, it sure ain't
a permanent solution and requires every contributor to
instruct their editor(s) to prevent or eliminate them.

Plus it's strongly recommended we all insert something
like what's shown below to our '.gitconfig' file so as
to provide at least some warnings when we try to apply
any patches (git am) that do contain the #@!%& things!

3e7f78d296 Add -p|--pretty option to uptime(1) for pretty output.
This patch adds the -p option to the uptime(1) command, which changes
the uptime displayed from something like:

 10:35:52 up  2:33,  1 user,  load average: 1.69, 1.65, 1.63

to:

 up 2 hours, 33 minutes

I originally implemented this as the up(1) program about 14 years ago.
In 2008 or 2009, I created a patch for procps to add this functionality
to uptime and submitted it to the project.  Never heard from the
project and no new releases of procps had been made.  Then I found out
about this project and decided to port my patch to it.  So here it is.

This is really just for fun.  There is no real technical reason to
have this functionality.  But even now, 14 years later, I still get
emails asking where the source code for up is.  So I thought it would
be nice for the uptime command on Linux to sport the up functionality
by default.

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.
