When the p/e-cores support (via the '5' key) was added
in the patch referenced below, I intentionally omitted
that key from the top primary help screen. This seemed
appropriate since it only applied to select Intel cpus
and, besides, that screen was getting kind of crowded.
[ it remains an objective to fit on a 80x24 terminal ]
Upon reflection, I found a way to squeeze it into that
help screen and have decided to included it. Hopefully
its presence will encourage use of top's new provision
on any Intel platforms that distinguish between cores.

In the commits referenced below special code was added
to make the bottom window sticky and fix the bug after
'Cap_nl_clreos' was traded for the 'Cap_clr_eol' loop.
However, there's always major overhead associated with
interacting with a terminal. So we'll only abandon the
single 'Cap_nl_clreos' putp in favor of repeated calls
with 'Cap_clr_eol' when a bottom window isn't present.

The man page said it cannot show changes to comm, such as when you
use prctl(). In fact, ps can see this. The args field may not change
because its due to the path of the executable but comm can.
The field comm no longer shows defunct for zombie processes, use the
state field for this as it could be obscured if not the last
column anyhow.

Put the man-po pot file under version control like its po/*.pot sibling.
Makefile now auto-matically generates the list of man pages as they are
in a single directory. There were some missing!
pot file target is dependent on the untranslated man pages
When downloading from translation project, run po4a to sync the new
po files correctly.
Downloaded man po files from translation project and synched.

Just as our library was made responsive to a potential
missing 'core id', the top program should also change.
That's because he has his own PRETENDECORE #define and
if that was activated on a platform without 'core id',
the 'CpP' notations would have otherwise been omitted.

In that commit referenced below, I removed the command
line help text from any translation so the TP wouldn't
delay our 4.0.1 release any further. In looking to the
future, when we might be able to reverse that, I found
gettext tools blocking use of the compile conditional.
They are too primitive for the original approach so we
must modify that exclusion mechanism hack accordingly.
____________________________excerpted program comments
The provision excluding some strings is intended to be
used very sparingly. It exists in case we collide with
some translation project person in a position to delay
a future release over his or her personal preferences.
If it's ever enabled, it will produce a fatal compiler
error as our only option since those gettext tools are
far too primitive to be influenced with a conditional.
They always ignore a '_X()' macro no matter its state.

Prior to this commit, when the '5' key was struck, top
would check for the presence of e-cores just one time.
That meant if a some cpu was brought online, and it in
turn exposed a new e-core after top has started, users
needed a top restart to activate the new '5' feature.
So, now we'll check for any e-cores with each '5' key.

I sure hope we won't disappoint the library with these
changes since we're only exploiting one of the two new
enumerators that the immediately prior patch provided.
Now top will be able to offer a visual clue as to each
cpu (thread actually) core association. Is it a P-core
offering multiple threads or a single threaded E-core.
We'll accomplish this feat with a subtle change to the
states portion ('t' toggle) of the summary area. Where
before processors were represented as 'Cpu', they will
now be displayed as 'CpP' (P-core) and 'CpE' (E-core).
[ assuming that new '5' command toggle has been used ]
There are also new provisions for filtering those cpus
by their core type association via the new '5' toggle.

With Intel's 12th generation Alder Lake processors now
providing two distinct types of core, it would be nice
if the library offered some sort of clue to core type.
Well, with this patch it does. We'll have 2 additional
enumerators. One deals with the cpu's core association
and the other provides the type of that core (P or E).
[ now, all we need is for some program to exploit it ]

When that 'Bottom' window was being finalized, an enum
of BREAK_screen was added to the Frames_signal values.
This was done so some full screen replacement function
could flag the need for that bottom window to go away.
Around that same time, top was made more responsive to
keyboard input so that residual portions of a previous
bottom window would not linger until the next refresh.
This happened if going from a larger (^N, environment)
bottom window to some smaller window (^P, namespaces).
The combined effect of these changes was to create the
potential race condition this commit addresses. If the
user encountered a SIGWINCH while on any of those full
screen replacement displays (help, fields mgmt, etc.),
endless redraws would occur. A ^C was the only option.
Henceforth we will protect against any redraw loops by
clearing Frames_signal each time a redraw is required.
[ along the way, we'll make the 'q' key work on that ]
t secondary 'windows' help screen as it should, even ]
[ though it is not documented on that screen itself. ]
