8d989c68c0 top: program code changes, enable NUMA/Node extensions
This commit extends the top Summary Area cpu states to
include information on Non-Uniform Memory Architecture
nodes. It is based upon changes originally proposed by
Lance Shelton who was instrumental in the final patch.

With this change, the user will have new commands that
will provide alternatives to the individual cpu stats:

. '2' toggles between cpu & numa node summary displays
. '3' provides node summary and related cpu statistics

These extensions required some minimal system support.
Typically, the numactl package (and maybe libnuma-dev)
are all that's needed to show a single node which owns
all the processors. Failing that, or for slightly more
variety, top also offers a #define named PRETEND_NUMA.

1b63eb8671 Improved regexp test for pmap
The change in pmap is necessary if it happens that the whole output of
pmap -X or -XX has been done before the second regexp is matched. Since
the matching is greedy, it is matched by the full output, so that
nothing is left for the third regexp and the test fails with
FAIL: extra extended output (footer).

7888f6a679 miscellaneous: clean up trailing whitespace once again
An earlier commit attempted to cleanse our environment
of all useless trailing whitespace. But the effort did

This commit hopefully finishes off the earlier effort.

526bc5dfa9 library: avoid SEGV if file2str should read zero bytes
When utility buffers were introduced for file2str read
requests, a subtle change was inadvertently introduced
such that a read of zero no longer returns a -1 value.

This commit ensures that zero bytes read returns a -1.

And although the solution differs from a merge request
submitted by sergey.senozhatsky@gmail.com, a thank you
is offered for revealing this potential abend problem.

6d605f521c library: make dynamic buffer management more efficient
When dynamic buffers were recently introduced for read
of the status, stat and statm subdirectories one extra
call to read() was required for end-of-file detection.

This patch avoids most all such extra calls to read().

Additionally, the frequency of memory reallocations is
reduced by overallocating each increase more than 25%.

4aa917455c top: fix the bug affecting certain Find/Locate results
When 'Other Filtering' was introduced the idea of what
constituted a displayed row changed. No longer was any
call to task_show assured of consuming one screen row.
Now the determining factor was whether or not the rows
were empty. This worked Ok until a certain Find string
was active then the entire display could be corrupted.

With Find active, the task_show() function alters each
returned row while highlighting each visible match. If
the search was on a single byte value & matched at the
beginning of a row the match got overwritten with '\0'
which then appears empty upon return to window_show().
So that row would not be counted as having been shown.

This was best illustrated with a Find on a single ' '.

This patch will restore proper 'Find/Locate' behavior.

a45dace4b8 library: utility buffers now immune to buffer overflow
A recent Debian bug report, dealing with release 3.2.8
and its even more restrictive buffer sizes (1024) used
in stat, statm and status reads via file2str calls, is
a reminder of what could yet happen to procps-ng. Size
needs are determined by kernel evolution and/or config
options so that bug could resurface even though buffer
size is currently 4 times the old procps-3.2.8 limits.

Those sizes were raised from 1024 to 4096 bytes in the
patch submitted by Eric Dumazet, and referenced below.

This patch makes libprocps immune to future changes in
the amount of stuff that is ultimately found in a proc
'stat', 'statm' or 'status' subdirectory. We now trade
the former static buffer of 4096 bytes for dynamically
allocated buffers whose size can be increased by need.

Even though this change is solely an internal one, and
in no way directly affects the API or the ABI, libtool
suggests that the LIBprocps_REVISION be raised. I hope
Craig remembers to do that just before a next release.

We don't want a repeat of the procps-ng-3.3.4 boo-boo,
but with no API/ABI impact that probably can't happen.

p.s. A big thanks to Jaromir Capik <jcapik@redhat.com>
who reviewed my original version and, of course, found
some of my trademark illogic + unnecessary code. After
his coaxing, he helped make this a much better commit.

a6c5e31022 top: tweak 'Inspect' code for isolated edge situations
If the 'Inspect' feature was used to view a file which
contained binary (unprintable) data, and when the last
line for such a file was purely unprintable, then that
line length would be overstated by the terminal width.

This was also the occasion where valgrind might object
over potential reference to some unitialized value(s).
It was a harmless situation and somewhat rare to begin
with. Anyway this commit will eliminate the potential.

Additionally, supporting readfile logic was simplified
and the 'status line' bytes read is now more accurate.

c80e93be47 pmap: a spade is a spade, so let's call a Flags a Perm
For some reason when the new -X/-XX options were added
what was always displayed as 'Mode' became 'Flags'. So
now a precious horizontal space is wasted because that
field's data has only 4 bytes whereas the header is 5.

Moreover, this created a conflict with the top program
which used that name in a column header already. Plus,
top emitted a 'Translation Hint' that suggests the max
chars should be 8 which is a limit pmap needn't share!

The xgettext program provides no way to keep identical
strings separate. This meant both top and pmap will be
sharing not only the msgid but a Translation Hint too.
So, the solution will now be two distinct field names.

Besides the kernel folks document it as 'perm' anyway!

0c0c543466 pmap: wield my machete, achieve width-wise nls support
The existing gettext nls support in pmap exposed users
to some potentially ugly misalignments should the text
that's used in headers someday actually be translated.

The length issue had been addressed already for -X/-XX
modes, but the column headers weren't nls translatable
as yet. This commit makes any header (not literally in
/proc/#/smaps) nls aware. It provides translated width
protection to all modes except one that's header-less!

As part of this effort, the occasional two spaces that
preceeded the Mapping column have been reduced to one.

3262143a29 pmap: trade inept width approach for printf's built-in
When the new -X/-XX options were introduced, the width
and justification requirements were satisfied with a 2
step approach. First, format strings would dynamically
be built and then employed in the subsequent printf().

This was a total waste of time and resources since the
printf family of functions provide for the '*' width &
precision conventions to meet this need via arguments.

But even more importantly that foolish endeavor always
hides the potential warnings like the one shown below.

Henceforth this pmap will printf in the proper manner!

1a50f39971 top: fine tune (ie. fix) 'other filter' negation logic
Two too many of these '=' (cooks) spoiled top's broth.

There exists an unintentional variation on the classic
error: off-by-one. When a negation symbol is used with
top's new relational 'other filter' provision, one too
many 'matches' are excluded. This happened because top
covered only 2 of the 3 potential strcmp return codes.
When the strings were equal, they were simply dropped.

So this patch will uninvent that particular variation!

This change represents the extension of user filtering

filtering provides an either/or choice, this extension
offers multiple choices applicable to multiple fields.

The 'inclusion' and 'exclusion' criteria can be freely

and avoid clutter associated with uninteresting tasks.

I'm convinced it offers unimagined future flexibility!

5e4bade595 top: minor refactor in preparation for other filtering
While it's only documented (so far) in commit text and
an occasional email I've tried to maintain some coding
standards primarily for reference/navigation purposes.
They also served, I felt, as useful mental challenges.

Someday I will get around to formerly documenting them
but in the meantime here are the ones for this commit:

. functions are grouped into logical (i hope) sections
. functions & sections are ordered to avoid prototypes
. function names are alphabetical within every section

Thus, given those constraints/objectives, and in order
to prepare for an upcoming Other_Filter feature, a few
things had to be renamed and rearranged. Plus a couple
of other (unrelated) tweaks were made for consistency.

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)

b9976f7056 top: finish the job of correcting the response to a ^Z
if top is suspended while on the 2nd level help screen
the <Enter> key is no longer honored. Thus, users must
use <Esc> to exit help and return to the main display.

Also, line input that was only partially complete when
suspended would still require one additional keystroke
before the read was aborted and the display refreshed.

Lastly, some user interactions might require two input
lines before an operation can be considered completed.
Thus the 2nd line offers another opportunity for users
to suspend top. Resumption would require an extra key.

These issues stem from 2 recent enhancements: preserve
the user context when signaled; complete input editing
with cursor movement keys, insert/overtype modes, etc.

With this patch, the <Enter> key is once again honored
on help screen #2 and partial reads are now completed.

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)
