29079d35e5 top: accommodate the loss of that OOMEM_ENABLE #define
Now that the conditional OOMEM_ENABLE has been removed
and all users exposed to those 'out of memory' fields,
it's about time we added them to the top man document.

32db4e99a6 library: make sure that the proc_t is now fixed length
The former variable length structure created potential
problems for library users like that referenced below.

We will now parallel the same approach newlib uses for
the configure options --enable-oomem & --with-systemd.
Thus, the --enable-oomem and OOMEM_ENABLE #define have
been eliminated and the --with-systemd option (#define
WITH_SYSTEMD) will hereafter impact one function only.

The proc_t struct itself will now *never* be impacted.

10503c03d4 top: make more responsive when toggling cpu off/online
Using the <STAT> api under the newlib branch, that top
program is very responsive to changes in the number of
on-line cpus. However under the master branch this top
program is very responsive only to losses of some cpu.

When a cpu is brought back on-line potential delays of
60 seconds could be encountered. That delay was simply
an attempt to reduce costs and reflected the erroneous
assumption that adding a cpu required physical effort.

So without redesigning the cpu refresh code to emulate
that of newlib, this commit just reduces the potential
delay to 3 seconds (the same that is used for memory).

[ As an aside, if one wants to have their confidence ]
[ in that htop program badly shaken, try taking some ]
[ cpus off-line & on-line again while it is running. ]

[ Poor ol' htop just continues to report results for ]
[ whatever were the cpus when started. Nice feature, ]
[ but I wonder where those phantom results are from. ]

ac8f49e79e top: miscellaneous accumulated tweaks of code/comments
This commit just tries to parallel that newlib branch.
It contains the following changes, which were prompted
by the newlib coverity analysis which Craig initiated:

. comment typo predicting 'String not null terminated'
. eliminate 'Logically dead code' from insp_make_row()

Some tweaks, unrelated to coverity, are also included:

. use more modern (recommended) approach for time call

5e26512980 top: extend 'zero suppression' scope to several fields
This commit just tries to parallel the implementations
in the newlib branch. The config file Rc.zero_suppress
will be extended to include both out-of-memory fields.

And while we're at it, we'll also extend zero suppress
to that NI (nice value) field, which already should've
had it. Plus we trade those namespaces custom suppress
logic for our now slightly enhanced make_num function.

5892540819 top: man page now includes resident memory enhancement
Since support already exists in the newlib branch this
represents an equivalent master branch implementation,
and this commit message is shared with 2 more patches.

Beginning with linux-4.5, the following new fields are
being added under that /proc/<pid>/status pseudo file:
 . RssAnon - size of resident anonymous memory
 . RssFile - size of resident file mappings
 . RssShmem - size of resident shared memory

p.s. Locked resident memory support was also added but
isn't directly related to the kernel 4.5 enhancements.

p.p.s. Archlinux, Debian-stretch and Fedora-23 already
are currently using a 4.5 linux kernel (as of 6/2/16).

3f5b75035e pidof: check cmd if space in argv0
A difference in behaviour between the sysvinit and procps pidof
was that the procps one would sometimes not find process that
the sysvinit one did.

The difference is that if a space is found in argv[0] then sysvinit
would look at cmd for a match. This isn't perfect and more of a
best guess but does often work.

procps pidof now follows the same "standard". The most obvious
difference is with kde based processes and incoming ssh connections
with sshd.

provided some much needed improvements and corrections

However, it assumed a reader possessed much background

this patch offers an expanded discussion of some terms
and concepts within a separate section under OVERVIEW.

e4bbd3ca1a top: improve/correct several memory fields in man page
Due to quirks in kernel memory management plus limited
information available from /proc/<pid>/status & statm,
some of the top resident memory fields were capable of
exceeding available physical memory. So this commit is
a bit of a band-aid until the kernel has been changed.

Such a change appears to be on the horizon in the form
of three new fields to be added to /proc/<pid>/status.
While not preventing 'resident' memory from apparently
exceeding physical memory, the new fields will help to
clarify any such contingency, if/when we exploit them.

717d73f1dd top: tweaks to vertical scroll management & 'i' toggle
The commit referenced below claims to disable vertical
scrolling when idle tasks weren't being shown. However
it really addresses only a point in time when that 'i'
toggle is keyed. Left untouched were the up/down keys.

So this commit will simply finish the job of disabling
vertical scrolling whenever tasks which have used some
CPU are the only ones which are currently being shown.

1af18812b2 enable transparent large file support
Historically LFS mattered only to open/read large files.  A few programs
here use open/seek, but not generally on files that are large.  However,
LFS also applies to stat which procps does in a bunch of places -- some
filesystems have 64bit inodes and attempts to do a 32bit stat will throw
an error.

Enable transparent LFS everywhere to avoid this.

da715e3ca0 Replace %Lu with standard %llu
Multiple scanf()s use the GNU-permitted %Lu. This is not supported in
other libraries and isn't to the POSIX specification. The L modifier
is only used for floats in POSIX.

Replacing %Lu with %llu is the same for GNU libc (scanf(3) says as much)
but means other libraries will work fine.

32e1b2e297 A locale-independent strtod
There is a need in some utilities to have a way of accepting both
types of decimal points "." and ",". The only way seems to be to
rebuild strtod().

This new function will accept "123.456" and "123,456" as 123.456
and considers them the same number. It means we lose thousands
separator, but this is rarely used.

test scripts are added to check the function returns the proper
values. There was simpler predecessor that got stuck on negative
0 or -0.123 which these tests flushed out.

94e4749be3 top: extend '=' key to include active 'locate' request
It is documented behavior that when certain other keys
are active, sorts column highlighting will temporarily
be disabled. Among those keys is the 'L' (locate/find)
provision. The equals ('=') key can be used to restore
column highlighting by resetting other keys, except 1.

When a locate/find is active, the '=' key will have no
effect on 'x' column highlighting, which still remains
disabled. Further, when 'L' is active an 'x' keystroke
is processed changing the state of column highlighting
but without any visual clue (since it's yet disabled).

So this commit just extends the '=' key to embrace 'L'
processing resets, just like other highlight disabling
keys while avoiding 'x' state changes if approproiate.

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.
