39f4067c66 top: kill/nice provide for a default pid
As an aid to the above 2 commands, and as a prelude to
an upcoming 'inspect other output' capability, the act
of selecting a process for either has been simplified.

Positioning a task as the first one displayed, via the
up/down arrow keys, will now establish it as a default
selection for the appropriate command.  Thus, that pid
will then be incorporated in a subsequent input prompt.

35cd340002 top: 'X' command offers auto option
The recent introduction of a column widths override
(the 'X' command) provided for a user input amount
to be added to default field size which ranged from
5 to 10 bytes.

While that approach could prevent truncated data, the
different default sizes would almost certainly mean
some precious screen real estate was waisted.

This commit introduces the concept of dynamic widths
where top will add only enough to a field default to
prevent truncation for that specific field.

Now users have a choice between their explicit width
override or a width chosen by top to exactly match
display needs.  The former is immediate but likely
wastes some horizontal space while the latter is
iterative but will be sized precisely.

Original 'X' Command:
commit 384afa494a
commit 47e1d063ac

Extensions to 'X' Command:
commit bbf8e44fb4
commit 7557f3f754

384afa494a top: optional wider non-scalable cols
This commit accommodates those fields which may have
suffered truncation due to these default limits:
  . 5 digits for uid/gid type fields
  . 8 characters for user/group type fields

With a new interactive command, users can increase the
width of all such fields, or return to the defaults.

Note:
   There are no restrictions on the amount added to
   the defaults.  The user is free to vastly exceed
   screen limits which simply means such fields can
   never be displayed.

This commit affords user control over justification
for both column headings and the subordinate data.

0f61354bf7 top: refactoring now allows column header nls support
Now that column headings are independent of column
data format and require no carefully managed padding
bytes they are candidates for nls translation.

This commit migrates all column headings to the .pot
file with additional translator guidance in the form
of maximum sizes to avoid truncation.

It also places these new additions adjacent to their
associated descriptions, which were already present.

fbfaa868ba top: improve scroll coordinates message handling
With the introduction of intra-column scrolling, the
scroll coordinates message was enhanced to give some
hint of positioning within a scrolled column.

Rather than rebuild this somewhat costly string from
scratch with each frame, we'll now do the bulk of the
work only when column headers are constructed.

The only remaining per frame costs will then be the
addition of a few terminfo escapes and the current
Frame_maxtask count.

2fc3f15770 top: refer to memory using strict IEC standard names
Admittedly, top referred to memory quantities in
a variety of non-standard ways.  This commit brings
the program and supporting documentation into strict
compliance with IEC standard binary names.

According to wikipedia, as of 2012 this IEC standard
was still not in widespread use.  However, I'm making
this change now for the anal-retentive among us.

4b98733132 top: honor the restrictive, crufty old top rcfile
At one time, new top silently defaulted when an rcfile
was found to be incompatible.  This is exactly what
the old top did.  However, after some discussion it
was decided top should alert the user and thereby
save the system administrator some headaches.

Now, some are upset over the fatal error, proving you
can't please everybody.  But in all fairness, given
the difficulty of customizing old top, any reluctance
to delete an old saved rcfile is understandable.

To ease transition to this new top, old style rcfiles
will now be honored and converted to the new format.
And if not disabled at ./configure time via CFLAGS,
a user will be warned when an old style rcfile is
about to be overwritten using the 'W' command.

Lastly, the config validation logic was enhanced to
help ensure both types of rcfile haven't been edited
manually and possibly made unuseable.

b246af9cec top: force newline for unexpected signal abnormal exit

db88a8d242 top: streamlined creation of nls string tables
The gettext documentation leads one to believe that
a printf type call is necessary for gettext string
extraction.  That turns out to be misleading and
all one really needs is the runtime gettext string
address resolution.

Thus, we can avoid our original snprintf/strdup
overhead and establish an address for the original
or translated string just by issuing the _() macro.

We create these nls string tables so that:
  1) top avoids the overhead of repeated
     runtime function calls
  2) we can control the order of top's
     strings in the .pot file
  3) translator comments don't obscure
     and clutter the main program

617d46633e top: redesign Uniq_nlstab/show_special (nls quirks)
Until this patch, top had used some strings with
special escape sequences to produce colors, normal
text, bold text, etc.  They took the following form,
explained by an excerpt from program comments:
  ...
  Our special formatting consists of:
     "some text <_delimiter_> some more text <_delimiter_>...\n"
  Where <_delimiter_> is a single byte in the range of:
     \001 through \010  (in decimalizee, 1 - 8)
  and is used to select an 'attribute' from a capabilities table
  which is then applied to the *preceding* substring.
  ...

Unfortunately, these nonprinting values revealed
insurmountable inconsistencies in both the front-end
and back-end translation tools.

The xgettext (extraction) program would take those
special escapes, convert them and then output raw
binary values.  Thus the .pot file would contain
lots of unprintable stuff making it unreadable.

If the following was added to po/Makevars, most of
those special escapes would be preserved in their
escape notation:
  XGETTEXT_OPTIONS = ... --escape
But two escapes were converted from octal notation
and there was no way to prevent it:
  \007  -->  \a
  \010  -->  \b

After a pass through the msginit program, most of
the escapes were reconverted to raw binary values
making translation impossible.  There was no
"--escape" option for the back-end programs like
there was for xgettext.

But the real killer was the escape \004, also used
in some of top's special strings.  This value would
be silently accepted by xgettext, only to produce
the following fatal error in back-end programs like
msginit, msgfmt and msgen:
  .pot:2647: context separator <EOT> within string

To quote from one of the references below:
  "Would you create a suite of tools that silently
   allow what is destined to become a fatal error
   to pass unnoticed?"

So the bottom line was: top's special strings, in
use for the past nine years, had to be redesigned.

3f7468082a top: finalized top nls support (or so he thought)
summary of changes:
. adopted relative paths to 'include' and 'proc'
  dirs so that stand alone compiles are made
  easier and no one need guess their locations

. corrected several names for enums and macro
  usage reflecting fmt vs. txt

. expanded all octal escape sequences to a full
  3 digits since one already required 3 digits

. finalized translator hints (for now)

programming note:
  as an aside, by not including an argument for
  the gettext --add-comments, any preceeding c
  style comment will be propagated to the .pot
  file, if the gettext macro isn't empty.
