Procps library previously held functions that were about either
listing or finding signal names. These are not really the right
location for a library about reading procfs.
This patch handles signal related functions in two ways:
For functions purely found in skill, these have been moved back
into this binary as they are used nowhere else.
For functions used across the binaries, these have been moved
into include/signals.h and lib/signals.c. Besides formatting,
these functions are largely the same.
To assist the skill functions, two functions to access the
signal map array have been added to lib/signals.c
If skill was used with a signal number then it would intepret
the command line with last option interpreted twice. This often
confused the program so it just would end up killing nothing.
So this would work:
skill -t pts/0
This would not:
skill -9 -t pts/0
The kill path (in the same file) uses the same logic that has
been introduced here.

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.

Commit 4359cf0698 restored kill's ability
to kill PID -1. This however left PIDs -2 to -9 (or rather process
groups 2 to 9) still having this problem. The check is now generically
looking for a digit and parses it correctly.
Both the man page and the shell builtin kill mention you can
use PID -1, which means nuke everything you can get at.
Alas this "fun" option was missing and the only way to get
around it was with "kill -HUP -- -1".
This small change means kill -HUP -1 is back for all those
destructive types. The error was introduced when the argument
parser was fixed for other problems.
Thanks to Mike for pointing this out.

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.

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.

kill would not permit negative PIDs and thought they were options. kill
now explicitly checks for unknown options and if they are numeric
assumes they are negative PIDs. The first negative PID stops any
further option processing.

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);

This commit broke `-l <sig>' conversion, which needs to be fixed
before kill can be claimed to work similar enough way as it did
earlier. The fix require libprocps change, because the current
