When invoked with the --chgexit/-g options wait until we have at
least one screen of output before checking if the output changed.
Otherwise, we're comparing the initial screen of output to all
spaces, which usually isn't what we want.
Revert commit ffe5e0b08e. Restores
clean exit when falling through main loop.
Previously, watch only exited when there was an error or when
interrupted by the user. Commit 81f64657ba
added another exit condition when the watched command's output
changes, causing execution to fall out of the main loop.
With this change, watch correctly restores the terminal and returns
an exit code indicating success when invoked with the --chgexit/-g
options.
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.

These per instance warnings have been eliminated:
warning: range expressions in switch statements are non-standard
warning: padding struct to align 'winflags'
warning: dereferencing type-punned pointer will break strict-aliasing rules
These per instance warnings have not been addressed
since they simply trade one warning for another:
From:
warning: ISO C does not permit named variadic macros
warning: ISO C does not support the '%Lu' gnu_scanf format
To:
warning: anonymous variadic macros were introduced in C99
warning: ISO C90 does not support the 'll' gnu_scanf length modifier
Lastly, since all C compilers have supported use of
C++ style comments for the past 20 years, the top
program will never trade them for the often more
cumbersome C style comments simply to avoid this
once per source file warning:
warning: C++ style comments are not allowed in ISO C90

Under openSUSE, old top uses additional fields for
out-of-memory reporting. As a result, under the
original approach to rcfile conversion, new top would
issue a fatal corrupt window entry message asking that
the rcfile be deleted.
This patch extends the conversion range to include
the extra openSUSE field characters. It's effective
when ./configure specifies the --enable-oomem option
which in turn defines OOMEM_ENABLE.
This commit also makes the conversion logic slightly
more forgiving. While enforcing an upper limit on the
expected number of old style field characters, amounts
less than that will be handled seemlessly.

Both these are from [-Werror=format-security]
sig.c:262:5: error: format not a string literal and no format arguments
global.c:517:3: error: format not a string literal and no format arguments
Under certain circumstances, using abort() when either make check
or make distcheck puts ps into an infinite loop around the
function catastrophic_failure() in ps and the C library raise
and abort functions.
Using exit removes this problem and does almost the same thing.
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.

Until the 'locate/search' provisions were added,
top avoided the need for any function prototypes
through careful source file organization. But
the addition of the find_string function required
a prototpe for task_show, lest a massive file
reorganization be undertaken.
This commit moves the actual protype out of top.h
and places it adjacent to the caller in order to
avoid a warning when top_nls.c is compiled.

At one time the 'open_psdb_message' library call was
supported with the concept of a postponed message
which would display after top startup completed.
In turn, that required logic to strip the '\n' which
was embedded (inappropriately) in any such message.
Nowdays top treats such a returned error as fatal so
there is no need for the 'strim' function which is
being removed with this commit.

We originally approached the potential problem of
% CPU distortions as unique to Nehalem type cpus.
The latest information suggests that it may have
been due to a kernel anomaly that has since been
corrected.
Yet even without such a cpu, wide disparities in
tics allocation among all available cpus have
sometimes been observed -- spikes as it were in
the normal pattern. This has happened under both
version 2.26.38-13 and 3.0.0-15 kernels.
The small amount of additional code addressing the
original problem carries very little overhead. It
is being retained to afford protection against any
future tic accounting aberrations.
In this commit, supporting programmer comments have
been divorced from any particular cpu type. Also,
another variable and manifest constant will now be
eliminated when CPU_ZEROTICS is defined.

When the calibrate_fields function was broken up for
mainainability, an obscure regression was introduced.
For the resulting bug to affect the display, all of
the following conditions would have to be met:
. USE_X_COLHDR was not defined
. column highlighting had been turned on
. many, perhaps all, fields were displayable
. the user then typed the <End> key
. and the current sort column just happened to
be immediately to the left of the left-most
visible field
This patch corrects for that remote possibility.
