If top were invoked under the 'screen' window manager,
writing the terminfo string 'exit_ca_mode' at top exit
would not restore the display to the state existing at
the time top was started. That's what occurs normally.
The net result of that failure was a corrupted screen.
However, there is a 'screen' configuration option that
will produce proper 'rmcup' behavior, but it is off by
default. That screencr option is known as 'altscreen'.
I stumbled across this provision by cloning the screen
git repository then searching for references to 'cup'.
If 'altscreen on' had been in either the /etc/screenrc
or the $HOME/.screenrc configuration file, my poor old
top would never have been accused of such corruptions.
Of course, the Programming Gods decree that any simple
solution for our problem must always be revealed last.
So before discovering that rc option, another approach
was taken involving top only. With just a little extra
refactoring of top display logic he was made immune to
any such quirk in the implementation of 'smcup/rmcup'.
I always feel good about any enhancement that actually
reduces the total number of lines of code. Even though
this change involved mostly rearranging some logic, it
yielded one less line (can't judge by diffstat because
of braces & notes). Anyway, rather than requiring some
change to a screenrc file, now we are self-sufficient.

This commit provides the hard copy support for our new
'Other Filter' feature. The man document contains some
potentially useful examples and it will be interesting
to see what use this new tool is put to in the future.

freeproc was missing from the libproc API which meant while you could
allocate proc structures, you couldn't free them!

We got a bug report, that our project doesn't spell "SELinux"
consistently/correctly. I've fixed that and the patch is attached.

Fix the build where it seems a code fix for Linux was likely untested
on other systems.
Define SCHED_BATCH in test-schedbatch, for systems that don't have it;
the corresponding RH BZ#741090 patch used the magic value 3 in output.c
anyway.

This message has been here for ages and either people ignore it because
they are so used to using -aux or never see it. It was here before 2005
and really 7 years is enought time to people to change their ways.
The notice is now removed, people who make usenames like "x" deserve all
the punishment they can get.
