cd8499f5f0 0015-tload: Prevent integer overflows of ncols, nrows, and scr_size.
Also, use xerrx() instead of xerr() since errno is not set.

44d5a5689c 0014-tload: Prevent a buffer overflow when row equals nrows.
When max_scale is very small, scale_fact is very small, row is equal to
nrows, p points outside screen, and the write to *p is out-of-bounds.

39c3542754 0012-tload: Call longjmp() 1 instead of 0.
Do it explicitly instead of the implicit "longjmp() cannot cause 0 to be
returned. If longjmp() is invoked with a second argument of 0, 1 will be
returned instead."

e6e228e7f4 Fix out of boundary write on 1x1 terminals
If a terminal is merely 1x1 in size, setsize() will write a nul byte in
front of the allocated memory, which is an out of boundary write.

ccb6ae8de1 library: cleanup of library includes
The includes used to define a lot of things a library include
should not. It was also a bit messy what was exposed in the library
and what was not.

get_pid_digits -> procps_pid_length and exported correctly

MALLOC attribute move into relevant .c files
NORETURN attribute moved to relevant .c, not used in library
PURE attribute removed, it wasn't used
KLONG/KLF/STRTOUKL were fixed for long, so now just use long

HIDDEN attribute removed. It was for 3 functions. The PROCPS_EXPORT
seems to do the same (opposite) thing.

likely/unlikely removed from most places, its highly debateable
this does anything useful as CPUs have gotten smarter about branches.

Re-arranged the includes, ALL external programs should just #include
<proc/procps.h> then proc/procps.h includes headers for files that
have exported functions. procps.h and the headers it includes should
not use items that are not exportable (e.g. hidden functions or
macros) they go in procps-private.h

2f975ba49d tload: fix lockup
It looks like an off by one error was added to tload a couple years
ago while removing goto statements.  This causes tload to go into
an endless loop when the load is just under a scale change integer.
eg: .99, 1.99, 3.99, 7.99

to reproduce you can add, just under the loadavg at line 170 in tload.c:
av[0] = 1.99;

or get the load to that level separately.

The patch below makes the code more like the original, but without the
goto statements.  This can also be fixed by just changing line 183 in
tload.c from "if (0 < row)" -> "if (0 <= row)".

6437aa08d4 Update options to single strings
To assist the translators, each option is a separate string.
This means if we add/change/delete an option the remaining ones
will just keep working and only the impacted option needs some
translation work on it.

7888f6a679 miscellaneous: clean up trailing whitespace once again
An earlier commit attempted to cleanse our environment
of all useless trailing whitespace. But the effort did
not catch 'empty' lines with a single space before ^J.

This commit hopefully finishes off the earlier effort.
In the meantime, let's pray that contributors' editors
are configured so that such wasted crap is disallowed!

042776e04c configure: check for program_invocation_name
For portabiliy, check for program_invocation_name during configure and
define HAVE_PROGRAM_INVOCATION_NAME accordingly. Use of this symbol is
now enclosed with the appropriate #ifdef block.

The symbol program_invocation_name is only used for error message
handling using error(), so it's safe to omit this if it is not
available.

fb11e1fe0a Changed the err and warns to macros
err and warn are BSD format but they are not recommended by library
developers.  However their consiseness is useful!

The solution is to use some macros that create xerr etc which then
just map to the error() function.  The next problem is error() uses
program_invocation_name so we set this to program_invovation_short_name

This is a global set but seems to be the convention (or at least errors
are on the short name only) used everywhere else.
