f858e563b7 top: preserved those new '4' and '!' toggles in rcfile
This patch will address Craig's feedback regarding the
original implementation of top's two new toggles. It's
likely other users would have questioned why they were
not saved also, once they discover these new features.

And, since the minimum terminal width was just lowered
to 80 columns, the default for window #1 is also being
changed to show the individual cpu graphs two abreast.

[ assuming no '--disable-modern-top' for ./configure ]

6db0d5eab6 top: reduce minimum terminal width with 2 abreast mode
For the original implementation of the '4' toggle, the
minimum width was set at 165 columns. This was done to
avoid truncations when detailed cpu statistics (versus
graphs) were being displayed. Those can not be scaled.

Upon reflection, it seems more appropriate to give the
user the choice of whether or not to truncate. And, by
reducing that minimum width requirement to 80 columns,
we'll vastly expand potential use of two abreast mode.

[ we'll keep that original as '#define TOG4_NOTRUNC' ]

The patch also updates the man document appropriately.
Along the way, we will trade the potentially confusing
word 'adjacent' for the more natural 'additional' when
detailing the '!' toggle in 4b. Summary-Area-Commands.

f7dc5b1728 top: for symmetry with 'E' add 'e' command line switch
Several years after the 'e' & 'E' interactive commands
were introduce to affect memory scaling, an 'E' switch
was added. This was after discovering a dropped Redhat
patch which provided a unique 'M' command line switch.

If only for symmetry it makes sense to offer a similar
command switch ('e') for the Task Area memory scaling.

As was true with 'E', top's help text will show 'e' as
if it were a switch without arguments in order to keep
help text displayed without wrap in an 80x24 terminal.
The man page, however, will show all of the arguments.

e7aa90a866 top: attempt to provide missing xterm vim keys support
A recent issue (and merge request) reminded me of gaps
in top's alternate 'vim' navigation keys support. Some
xterm emulators do not pass the customary strings when
keys were used with the <Ctrl> and/or <Alt> modifiers.

While it was a known problem, this issue/merge request
prompted research into the root cause. As it turns out
the problem is traceable to an X resource known by the
name 'eightBitInput'. When 'true' (the default), a key
pressed in combination with <Alt> will not be preceded
by the <Esc> character. Rather, a single character was
presented (modified via an 'eightBitMeta' X resource).

The following approaches would eliminate this problem:

. start xterm thus: xterm -xrm '*eightBitInput: false'

. use: ~/.Xresources with 'Xterm*eightBitInput: false'

. build xterm with 'configure --enable-meta-sends-esc'
( apparently used for CentOS, Fedora, openSUSE, etc. )

. enable xterm's menu via 'configure --enable-toolbar'
( so the user can set the 'Meta Sends Escape' option )

Of course, none of the above steps is desirable from a
user's perspective. So, this patch will add additional
entries to the iokey function's tinfo_tab to represent
strings passed when the <Alt> key does not send <Esc>.

[ hopefully they'll be the same across all platforms ]

Lastly, this patch will also eliminate those redundant
<Atl> + '\', '/', '<' & '>' provisions, which now seem
like overkill and suffer from that same 'eightBitMeta'
xterm problem. And we might as well say goodbye to the
4 '<Alt> + arrow key' table entries (which do not seem
to currently work with any emulator which I can find).

[ what in the world was I thinking way back in 2011? ]

Using Ctrl-V for the collapse children key now appears
as a mistake. First, it's too close to that Ctrl-C key

While it's only documented (so far) in commit text and

They also served, I felt, as useful mental challenges.

Someday I will get around to formerly documenting them

. functions & sections are ordered to avoid prototypes
. function names are alphabetical within every section
. all functions & sections must be referenced in top.h

This patch just attempts to honor the above standards,
while also covering this new behavior in the man page.

a238a687ce docs: Document I idle state in ps and top
Linux 4.2 provided a new process state of I which is used for an idle
kernel thread. This new state means that kernel threads do not
contribute to the loadavg as they are no longer state D or S but I.

While both ps and top displayed this state, it wasn't documented in
either manual page until now.

3e6a208ae5 top: allow more flexible approach for startup defaults
Those references below offer more detail regarding the
default startup changes beginning with version 3.3.10.

It is important to remember that all such changes were
supposed to impact only new users or users who had not
saved the personal config file (via that 'W' command).
However, I introduced a bug wherein the rcfile was not
fully honored. This gave the changes a bad reputation.

That bug was corrected in release 3.3.11 but the issue
of default startup options keeps resurfacing. And it's
clear there's no consensus on what should be included.

Our --disable-modern-top configure option is of little
help since it remains an all-or-nothing approach. What
we need is an answer offering unlimited customization.
So, this commit will provide distribution packagers or
system administrators with a much more flexible way to
set their own preferred startup default configuration.

A new rcfile is being introduced: '/etc/topdefaultrc',
whose format/content is the same as a personal rcfile.
Thus once a 'proper' enterprise configuration has been
established and saved via 'W', it can be copied to the
/etc/ directory. Thereafter, startup in the absence of
a saved rcfile will use that configuration as default.

Now if a distribution packager or system administrator
wishes to expose their users to some of top's advanced
capabilities they can do so gradually. Perhaps setting
up graph mode for summary area task and memory display
while retaining the %CPU sort could be tried. Or maybe
showing colors, but better customized for a particular
terminal emulator. Such possibilities are now endless.

[ in exploiting this new capability, i hope that the ]
[ other windows (alt display mode) aren't overlooked ]

89db82d143 top: provide -1 command line switch as 'Cpu(s)' toggle
If built without ./configure --disable-modern-top, the
program displays each cpu individually providing there
is sufficient vertical screen real estate. For massive
SMP environments this will necessitate use of a config
file where the cpu summary toggle ('1') could be saved
via the 'W' command. But, an rcfile may not be viable.

So this commit introduces a '1' command line switch to
emulate exactly the effects of the interactive toggle.

And since it is our first numeric switch some existing
parsing logic had to be changed slightly. Such changes
are, in truth, an improvement. For example, instead of
seeing "inappropriate '2'" with ./top -2 we'll now see
the vastly more appropriate error "unknown option '2'.

fb48b5d9fb top: provide -E command line switch for memory scaling
In their 3.2.7 version of top, Redhat introduced an -M
switch to automatically scale Summary Area memory data
to avoid truncation (and the resulting '+' indicator).

The procps-ng top does not employ suffixes with memory
data nor does it allow for different scaling with each
separate value. Rather, scaling appears at line start.

If built without ./configure --disable-modern-top, the
Summary Area memory will be scaled at GiB which should
lessen chance of truncation. Otherwise KiB was used to
reflect such memory, increasing the truncation chance.

And while 'W' can be used to preserve some appropriate
scaling value, there are arguments against such rcfile
approaches as cited in the issue and bug report below.

So this commit will bump the Summary Area memory scale
factor from KiB to MiB when using --disable-modern-top
as a concession to that Redhat bug report noted below.

And it also introduces a new command line switch which
can force any desired scaling regardless of the rcfile
or which ./configure option might have been specified.

[ for top's help text we'll show 'E' as if it were a ]
[ switch without arguments in order to keep the help ]
[ text displayable without wrap in an 80x24 terminal ]

[ the man page, however, will show all k-e arguments ]

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.

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.

c437faf8d3 library: evolve MenAvailable algorithm on older kernel
Let's not report zero for kb_main_available when older
kernels don't have MemAvailable. Instead, if we simply
duplicate the 'free' amount we can avoid all ancillary
problems, such as those involving top's graphing mode.
