8e7ef322e2 Update help files
Benno Schulenberg suggested some changes to the help messages
to provide some consistency and clarity for both the users and
translators of procps.

The test needed to be updated as the pmap output changed too.

8a38cd5eb4 Split help lines to help translators
To assist translators, the help lines are split so that each translation
chunk has one option. This gives bonus of if we add or change an option,
only that option remains untranslated rather than the entire help block.

static int one_proc(proc_t * p)..

rightfully results in an overflow and the program aborts.

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.

c80e93be47 pmap: a spade is a spade, so let's call a Flags a Perm
For some reason when the new -X/-XX options were added
what was always displayed as 'Mode' became 'Flags'. So
now a precious horizontal space is wasted because that
field's data has only 4 bytes whereas the header is 5.

Moreover, this created a conflict with the top program
which used that name in a column header already. Plus,
top emitted a 'Translation Hint' that suggests the max
chars should be 8 which is a limit pmap needn't share!

The xgettext program provides no way to keep identical
strings separate. This meant both top and pmap will be
sharing not only the msgid but a Translation Hint too.
So, the solution will now be two distinct field names.

Besides the kernel folks document it as 'perm' anyway!

0c0c543466 pmap: wield my machete, achieve width-wise nls support
The existing gettext nls support in pmap exposed users
to some potentially ugly misalignments should the text
that's used in headers someday actually be translated.

The length issue had been addressed already for -X/-XX
modes, but the column headers weren't nls translatable
as yet. This commit makes any header (not literally in
/proc/#/smaps) nls aware. It provides translated width
protection to all modes except one that's header-less!

As part of this effort, the occasional two spaces that
preceeded the Mapping column have been reduced to one.

3262143a29 pmap: trade inept width approach for printf's built-in
When the new -X/-XX options were introduced, the width
and justification requirements were satisfied with a 2
step approach. First, format strings would dynamically
be built and then employed in the subsequent printf().

This was a total waste of time and resources since the
printf family of functions provide for the '*' width &
precision conventions to meet this need via arguments.

But even more importantly that foolish endeavor always
hides the potential warnings like the one shown below.

Henceforth this pmap will printf in the proper manner!

d454bfe902 pmap - removing the column width constraints in the -X/-XX modes
This commit changes the width measurement principle in the -X/-XX
modes so that a width of totals is measured instead of the width
of summands. The value of totals is always higher than the value
of summands. That additionally prevents the totals from having
a wrong indentation.

This commit also removes the minimum column width constraints
hardcoded to 7 characters.

20ce346ebd pmap: fixing broken indentation in the -X/-XX modes
This commit changes the processing principle of the -X/-XX modes
from 1-pass to 2-pass. A separate width measurement stage has been
added, so that the real maximum widths can be measured and used
for correct indentation.

The firstmapping variable now has a new value (2) used for the
width measurement stage (1st pass). The printing is disabled
in this stage. The file position is reset to the beginning
of the file once the end of file is reached and the printing stage
(2nd pass) begins.
It's questionable if this approach is sensitive to Read-after-Write
race conditions. Anyway, this feature is a good candidate for
a complete redesign in the future.

Additionally this commit introduces a final cleaning of the list
used for the evaluation of totals in the -X/-XX modes.

365a5fa517 pmap: empty output or crashes on ppc/s390 caused by wrong pidlist type
Previously the pidlist variable was defined as unsigned long *
whilst the openproc function accepts pid_t *.
Both target types differ in size (8 != 4) and therefore the issue
mainly affects big endian architectures.

This commit changes the pidlist type to pid_t * so that it's
compatible with openproc.

dca3c6d08f pmap vmflags support
Some new kernel version added a line in /proc/pid/smaps listing a processes vmflags. This broke pmap such that pmap -X and pmap -XX would always fail.

This patch adds support for the vmflags field so that -X and -XX work again AND they display the flags.

7e8ee148d7 pmap avoid SEGV potential with new X/XX detail options
While permissions suggests that /proc/#/smaps contents
are world-readable, in practice this file might not be
available to a non-root process. Whether this is a bug
in the kernel or an intentional design decision really
makes no difference. This commit will protect pmap -X.

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)

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.
