bb1a79f2c8 library: correct that 'escape_str_utf8' guy's behavior
Thanks to Konstantin for discovering 2 problems in the
issue referenced below. That 15+ year old logic went a
little too far overboard wrestling with a utf8 string.

Henceforth, we will not treat 'x9b' as special. And we
also will handle a 'combining acute accent' correctly.

e3249ebb97 top: some miscellaneous accumulated tweaks and cleanup
I've grown to hate that man document rendering when it
comes to hyphenation. So this patch will eliminate it.

And we'll also eliminate an unnecessary initialization
in that top program code concerned with combined cpus.

f0fb35b645 top: fix a minor startup flaw for the '2 abreast' mode
This ensures that a single '4' keystroke will reliably
toggle the new 2 abreast mode ON. Depending on whether
an older configuration file existed or whether top was
configured with '--disable-modern-top', keying the '4'
for a second time might otherwise have been necessary.

f73d8d180f top: help the '#define PRETEND48CPU' be more realistic
The previous PRETEND8CPUS #define was recently changed
to PRETEND48CPU to better exercise the new '4' and '!'
toggles. But, the implementation simply duplicated the
/proc/stat summary line for each cpu. Therefore, every
cpu showed the same graph/detail (depending upon 't').

This patch shows the actual individual cpu information
(duplicated, of course, when total cpus are exceeded).

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 ]

ad6917e3cf top: warn users if rcfile save prevents older top read
I'm about to break older top rcfile compatibility when
preserving those two new toggles. And, though this has
happened several times over the years, we never issued
any warnings that such thing was just about to happen.

So, this patch corrects the long standing shortcoming.

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.

5e1e14b019 top: add '!' toggle for combined cpus display, program
When implementing that earlier '4' toggle, in response
to the issue referenced below, I got to thinking about
those environments with massively parallel processors.

Such environments may not benefit from the '4' toggle.

So, I decided to implement a feature that could enable
use of those '1' and/or '4' toggles no matter how many
active processors top may have ultimately encountered.

With the new '!' toggle, adjacent cpus can be combined
to any degree, represented as a single cpu group/line.

fca48e7e99 top: add '4' toggle for 2 abreast cpu display, program
In the back of my mind, I've always wanted to enable a
two abreast cpu display. Folks with massively parallel
machines must surely have been frustrated with the '1'
toggle when Off (individual cpus in the Summary Area).

So, I'll use that recently raised issue shown below as
a justification for finally implementing this feature.

4090fa711b build-sys: Enable testing of sigqueue
The referenced commits enavled both pkill and kill to send an integer to
the killed or signalled process. The test_process now will report on the
integer if sent and the testsuite changes take advantage of this
new feature.

Another process make/destroy set had to be made as using spawn
instead of exec changes both the SID and TTY for the underlying
process, making other tests fail.

91a396d76e free: Adjust space to really use 9 chars
@steffhip found that while the translation hint said use 9 characters in
the free headers, it really was only 7.

Currently each line is constructed with the following (in non wide format):
Header + 6 Columns.  The header takes 7 characters and each column is 11
characters wide and prefixed with one space. Thus we have
7 + (1 + 11) * 6 = 79 characters for each line

By dropping the leading space for the first column after the header -the
header is already terminated by a colon- one could indeed provide the needed
9 letters for the header and thus have 9 + 11 * 1 + (1 + 11) * 5 = 80 Chars
per line which would fit into one line.

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.
