Jim Warner 29f0a674a8 top: introduce background updates via separate threads 
After the stage had been set in the previous patch, in
this patch we will actually implement those background
updates via 3 separate threads. The design was simple:

. the do-while loops have now been made truly infinite
. 2 semaphores per thread allow needed synchronization
. 1 semaphore will provide for each thread to sem_wait
. 1 semaphore will provide for display o/p to sem_wait
. and all 3 thread's program name was made descriptive

A complication was the potential for a signal directed
to one of our new threads. Rather than having a thread
try to deal with such signals, we pass a mask with all
signals blocked at pthread_create time. Thereafter any
subsequent signals are forwarded to the parent thread.

[ also sigprocmask was exchanged for pthread_sigmask ]
[ since warned about use "in multithreaded process". ]

[ plus we also modified each of those POSIX comments ]
[ about 2004 to agree with current signal-safety(7). ]

Sadly, after all this effort there were no performance
benefits to having separate threads. In fact there was
a measurable performance degradation when running with
ever smaller delay intervals. But even with a delay of
1/10 second the 'real' cost increase is only about 1%.

There is one way whereby any additional costs might be
eliminated (at least seemingly). One could introduce 2
separate sets of contexts for each of those 3 threads.
Then retrieval & display could be overlapped. However,
the resulting display wouldn't represent the real-time
results. Rather it would be stale by 1 delay interval.

// Programmer Note(s):
// Preparation ---------------------------------------------
// Unless you have *something* following the gettext macro,
// xgettext will refuse to see any TRANSLATORS comments.
// Thus empty strings have been added for potential future
// comment additions.
//
// Also, by omitting the argument for the --add-comments
// XGETTEXT_OPTION in po/Makevars, *any* preceding c style
// comment will be propagated to the .pot file, providing
// that the gettext macro isn't empty as discussed above.
// However, this is far too aggressive so we have chosen
// the word 'Translation' to denote xgettext comments.
//
// /* Need Not Say 'TRANSLATORS': ...
// snprintf(buf, sizeof(buf), "%s", _( // unseen comment
//
// /* Translation Hint: ...
// snprintf(buf, sizeof(buf), "%s", _("" // now it's seen!
//
// Translation, from po/ directory after make --------------
// ( this is the procedure used before any translations were )
// ( available in the po/ directory, which contained only the )
// ( procps-ng.pot, this domain's template file. )
//
// ( below: ll_CC = language/country as in 'zh_CN' or 'en_AU' )
//
// msginit --locale=ll_CC --no-wrap
// . creates a ll_CC.po file from the template procps-ng.pot
// . may also duplicate msgid as msgstr if languages similar
// msgen --no-wrap ll_CC.po --output-file=ll_CC.po
// . duplicates every msgid literal as msgstr value
// . this is the file that's edited
// . replace "Content-Type: ... charset=ASCII\n"
// with "... charset=UTF-8\n"
// . translate msgstr values, leaving msgid unchanged
// msgfmt ll_CC.po --strict --output-file=procps-ng.mo
// . after which ensure, chmod 644
// . then copy
// to /usr/share/locale-langpack/ll_CC/LC_MESSAGES/

. It is strongly recommend that the --no-wrap command line option
. be used with all supporting translation tools, when available.
.
. The following line pairs contain only plain text and consist of:
. 1) a field name/column header - mostly upper case
. 2) the related description - both upper and lower case
.
. To avoid truncation on the main top display, each column header
. is noted with its maximum size, while a few are 'variable' width.
. Names for the latter should probably be 10 or fewer characters.
.
. Those fields shown with a '+' are also eligible for user resizing
. using the 'X' command. That means the default width might produce
. truncation but need not if widened (see the man page 'X' command).
.
. All headers are subject to a maximum of 7 on the Fields Management
. screen where truncation is entirely acceptable.
.
. The associated descriptions are always limited to 20 characters,
. and are used only on the Fields Management screen.
.
. In all cases, fewer characters are just fine.

/* Translation Notes ------------------------------------------------
. It is strongly recommend that the --no-wrap command line option
. be used with all supporting translation tools, when available.
.
. The next several text groups contain special escape sequences
. representing values used to index a table at run-time.
.
. Each such sequence consists of a tilde (~) followed by an ascii
. number in the range of '1' - '8'. Examples are '~2', '~8', etc.
. These escape sequences must never themselves be translated but
. could be deleted.
.
. If you remove these escape sequences (both tilde and number) it
. would make translation easier. However, the ability to display
. colors and bold text at run-time will have been lost.
.
. Additionally, each of these text groups was designed to display
. in a 80x24 terminal window. Hopefully, any translations will
. adhere to that goal lest the translated text be truncated.
.
. If you would like additional information regarding these strings,
. please see the prologue to the show_special function in the top.c
. source file.
.
. Caution:
. The next three items represent pages for interacting with a user.
. In all cases, the last lines of text must be treated with care.
.
. They must not end with a newline character so that at runtime the
. cursor will remain on that final text line.
.
. Also, the special sequences (tilde+number) must not appear on the
. last line (the one without the newline). So please avoid any line
. wraps that could place them there.
