bbebf29dd1 ps: adapt to the newly added library smaps_rollup item
In that commit referenced below, a new field was added
to the ps program which required adding 2 newlib items
together. Such a need is now satisfied by the library.

So, this commit will just adapt ps for that provision.

e782b1d859 ps: Add PSS and USS fields
The library added smaps_rollup fields in the referenced commit.
This commit exploits the new fields to give pss and uss options.

These options were first proposed back in 2015 by Petr Malat
and, with the library update, they are finally made it into ps.

Why use proportional or unique segment size? It is argued that
these give a better idea of the "real" memory usage of a process.

605ea4a8f7 library: make that 'escape_str' private to our library
In that commit referenced below, a promise was made to
revisit an 'escape_str' function in efforts to make it
private to the library. The problem was it's needed by
both ps plus the library which is why it was exported.

So, in an effort to remove it from libprocps.sym, this
patch duplicates all the required code in ps/output.c.
Now, each version can be made private to their caller.

[ along the way we'll use this opportunity to remove ]
[ the 'restrict' qualifiers from function parameters ]
[ while swatting a compiler warning referenced below ]

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.

* Only functions will begin with that 'procps_' prefix

* 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

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.

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

b2f49b105d Closes: #9 ps: Remove Unix98 output limitations
ps previously followed the Unix98 standard when it comes to
user-defined output, sometimes. This meant you could have
user output format with a header that included commas and
equals signs. It was dependent on if ps thought you wanted
sysv or bsd format and THAT was dependent on things in previous
options.

It was very confusing to a user because
 ps p $$ -o pid=,comm=
gave you a two-column output but
 ps -p $$ -o pid=,comm=
would give you a one column output with the header ",comm="

The -p versus p means (to ps) you want sysv or bsd parsing.
Unix98 standard or not, this is plainly just silly.

The commit removes any of the quirks Unix98 has with user defined
output.  If you really wanted a ps header with commas in the output,
today isn't your day.

584028dbe5 ps: exploit those new <pids> task/threads capabilities
This commit represents the ps transition to the <pids>
'stacks' interface. While an effort to minimize impact
on existing code was made (as with a disguised proc_t)
the changes were still extensive. Along the way, a few
modifications beyond simply conversion were also made.

------------------------------------------------------
Here's a brief overview the design of this conversion:

. The need to satisfy relative enum requirements could
not easily have been made table driven since any entry
in the format_array might require several <pids> items
in support. So I decided to allow every print function
to contribute its own relative enums once the decision
as to exactly what will be printed had been finalized.

. A similar approach was taken for sorting, since it's
possible to have sort keys that will not be displayed.
Here, I relied on the existing print extensions above.

. In summary, just prior to printing ps walks thru two
lists one time (the format_list & sort_list) and calls
each print function. That function does not print, but
sets its required enum if necessary. Later, when those
same functions are called repeatedly for every printed
line, the only overhead will be an if test and branch.

------------------------------------------------------
Below is a summary of major changes beyond conversion:

. Sorts are now the responsibility of the library. And
therefore the total # of sortable fields substantially
increased without effort. Additionally, several quirky
fields remain as sortable, even though they can't ever
be printed(?). Surely that must make sense to someone.

[ while on this subject of sort, please do *not* try ]
[ to sort old ps on 'args'. or better yet, if you do ]
[ try that sort, see if you can determine his order, ]
[ without peeking at the source. that one hurts yet! ]

. All logic dealing with the old openproc flags and ps
struct members known as 'need' have been whacked since
that entire area was solely the new library's concern.

. Remaining malloc/calloc calls to stdlib were changed
to xmalloc/xcalloc from our own include/xalloc.h file.
None of the replaced calls ever checked return values.

[ be aware that 2 minor potential memory leaks exist ]
[ depending on command line arguments. no attempt is ]
[ made to free dynamically acquired format/sort node ]
[ structures upon return; a conscious design choice. ]

caeebdc71f ps: exploit the simplified library interface for wchan
This patch was made necessary by those library changes
in support of recently revised/simplified wchan logic.

In addition, this commit eliminates a broken alternate
'namelist' provision which was intended to allow users
to specify a System.map file to be used in translating
addresses into function names. But, the real effect of
the now defunct 'N' and '-n' options was to indirectly
force addresses (not names) to be displayed since such
user named map files could not be successfully parsed.

Besides when the required FRAME_POINTER kconfig option
is absent there is no address to translate and when it
is present /proc/PID/wchan is already translated. Thus
an alternate mapping is unnecessary and inappropriate.

[ we'll forgive POSIX for documenting '-n  namelist' ]

e751606fcc ps: add -q/q/--quick-pid option
This commit introduces a new option q/-q/--quick-pid
to the 'ps' command. The option does a similar job
to the p/-p/--pid option (i.e. selection of PIDs
listed in the comma separated list that follows
the option), but the new option is optimized
for speed.
In cases where users only need to specify a list
of PIDs to be shown and don't need other selection
options, forest type output and sorting options,
the new option is recommended as it decreases
the initial processing delay by avoiding reading
the necessary information from all the processes
running on the system and by simplifying
the internal filtering logic.

4fb48c0bdb ps: generalize help text logic, add related translator hints
This commit represents an experiment in nls help text support.

The word --help itself been made translatable along with the
help section names and their abbreviations.  Thus, the work of
the translators will ultimately alter program run-time behavior.

Perhaps someday all "long" options can behave in a similar way
which could offer a considerable benefit to other languages.
Instead of translationg just option descriptions, the long
forms of those options could also be transalated.

This commit also:
 . includes the section abbreviations in --help output
 . isolates all --help support in the ps/help.c module
 . provides (hopefully) meaningful Translator guidance
 . removes --help support from the ps/common.h header
 . removes --help support from the ps/parser.c module
 . eliminates tabs in line with the style of other ps modules
 . eliminates the need for the include/c.h header file
