This commit prevents pkill from accepting something like `-1garbage` as
a SIGHUP. The previous code was using atoi() which does not check for
trailing garbage and would parse the above as 1.
Handling numeric signals in signal_option() is not really necessary,
since signal_name_to_number() will recognize numeric signals and parse
them properly using strtol() and checking for trailing garbage. It also
checks that the numeric signals are in the proper range. So all we need
to do is remove the buggy numeric signal handling here.
Tested with `pkill -1garbage sleep`, after this patch it will complain
that "1" is not a valid option, which is the expected.

It doesn't make any sense to have the binary version strings
embedded into the library. The version strings are defined
already either in the Makefile or in include/c.h
Recent commit 9742c74e7c ("pgrep: Enable case-insensitive process matching")
caused the "opts" string to overflow the show 32-character space allocated for
it.
Bump it up to 64 bytes, which should be enough even if more options are added.
Tested: Running ./pgrep stopped crashing and `make check` passed.

FreeBSD has case-insensitive matching of processes in pgrep and
pkill, which can be super-useful. This patch uncomments and

The loop that parses options has a of by one bug where the realloc
adds one byte, instead of one list element. This is exposed when
you try things like:

The pgrep usage() rework commit from 26-Sep-2011 introduced
a regression in exitcodes and the pgrep tool now returns
EXIT_FAILURE (1) or even EXIT_SUCCESS (0) instead
of the documented EXIT_USAGE (2). This commit fixes
the usage() so that the exitcodes match the manual.
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.

pgrep does not show the full command line when the -a and -u flags are
combined. The -a flag is ignored when the -u flag is used as well.
In addition, the supplied patch by Elliot did not fix the problem
when invert flag ( -v ) was used; a very small tweak to the patch
fixed this problem as well. This problem existed before.

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.
Additional errors resulting from merge request #13 are
being addressed in this commit. They involve two cases
of trailing whitespace and one xwarnx printf type arg.

A PID should be specified with --ns:
$ pgrep --ns 12345
which will only match the processes which belong to to the same 6
namespaces. It is also possible to specify which namespaces to test:
$ pgrep --ns 12345 --nslist mnt,net,ipc
which will match processes that belong to the same mount, network and
IPC namespaces as PID 12345.

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!

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.
The entire tree's polluted with inappropriate trailing
whitespace. This commit rids our environment of all of
those useless keystrokes. Unfortunately, it sure ain't
a permanent solution and requires every contributor to
instruct their editor(s) to prevent or eliminate them.
Plus it's strongly recommended we all insert something
like what's shown below to our '.gitconfig' file so as
to provide at least some warnings when we try to apply
any patches (git am) that do contain the #@!%& things!

Commig a5d9c40262 caused signal spec,
again, to be required as first option; for example
pkill -3 <program> # worked
pkill <program> -3 # did not
This commit fixes the regression, without breaking option -u <numeric>
argument, assuming no-one is using negative numeric UID specifications
with space after -u && the argument. IMHO such use case is rare enough
to be broken.

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.
Add the following three functions to most of the commands.
setlocale (LC_ALL, "");
bindtextdomain(PACKAGE, LOCALEDIR);
textdomain(PACKAGE);
