This commit introduces an extremely powerful, flexible
brand new capability. Now, users can pause the normal
iterative display and inspect the contents of any file
or output from any script, command, or even pipelines.
It's invoked via the 'Y' interactive command which, in
turn, is supported with simple user supplied additions
as new entries in the top personal configuration file.
A separate new 'Inspect' window supports scrolling and
searching, similar to the main top display. Except it
extends existing 'L'/'&' (locate/locate-next) commands
so that an out-of-view match automatically adjusts the
horizontal position bringing such data into view. And
it provides for multiple successive same line matches.
Also, the basic 'more/less' navigation keys are active
in this new 'Inspect' window, to ease user transition.
There are no program changes required when entries are
added to or deleted from the rcfile. And there are no
known limits to the complexity of a script, command or
pipeline, other than the unidirectional nature imposed
by the 'popen' function call which top cannot violate.
Since it's impossible to predict exactly what contents
will be generated, top treats all output as raw binary
data. Any control characters display in '^C' notation
while all other unprintable characters show as '<AB>'.
The biggest problem encountered was with the find/next
capability since that strstr guy was really diminished
given the possibility that numerous 'strings' could be
encountered *within* many of top's raw, binary 'rows'.
Oh, and another problem was in maintaining the perfect
left & right text justification of this commit message
along with all of the commit summaries. Some of those
summaries (like this very one) are of course, slightly
shorter, to make room for the 'man document' addition.
Enjoy!

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.

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.

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.

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.

This commit corrects some outdated programmer comments.
Additionally, certain nls justifications might become
increasingly obscure with the passage of time so some
previous nls commit text has been added as comments.
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.
