The first part of fixing skill/snice to use the library instead
of directly readdir()ing /proc which is what it does now.
Remove the kill code from the skill/snice code and put common
elements into lib/signals.c Not 100% sure that is the right
destination instead of a new lib file, but ok for now.
kill shares some parsing logic with skill/snice but mainly
around signal specifications. The "do it" code is very different.

Functions related to namespaces were half-in half-out of the
procps library and didn't fit the standard naming scheme.
While struct { long ns[x]} is a bit clunky, its the only way
to "lock in" x. The alternative is to use ns_* variables.
This work was needed before pgrep could be converted.
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
For the test suite, procps used to use sleep which would just
create a process or two to test the tools against. Some setups
coreutils creates all programs including sleep into one blob which
means a lot of the tests fail, see issue #2
procps has its own sleep program now.
This will be required for subdir-objects, otherwise automake will have
problems with more than one Makefile.am having rules to build the same
files.
Tested that it builds and both `make check` and `make distcheck` work.
Tested `make install` and compared the tree with the one installed
before this commit, both installed the binaries to the same locations.
The binaries are also in the same location in the build tree (for
instance, ps/pscommand is still there.)
Checked the binaries for the correct libraries linked into them. Binary
sizes matched before and after this change.

In order to avoid compiling the same source files twice, with and
without the TEST_PROGRAM define.
Tested that the build still works and that `make distcheck` works as
expected.
Tested that the test_* programs in lib/ keep working. (Though they are
not really invoked by `make check` and in particular test_nsutils is
quite useless, test_fileutils also quite poor.)

This is required for out-of-tree build to work, since many source files
include e.g. proc/*.h which is not under the include/ directory.
Tested that `make distcheck` starts working after this patch.

The previous commit removes the stdio_ext.h header,
but the ns_read function calls snprintf that needs
stdio.h and therefore moving the stdio.h include
from the bottom test program to the top line.
The <stdio_ext.h> include breaks building on platforms without that header and is unused in nsutils.c.
Also remove unused but harmless <error.h> include.
The translated manpage generation has moved from scripts to
Makefiles. This asists with conditional building as well, no
need to regenerate the German pgrep man page if both
the original pgrep.1 and man-po/de.po is not changed.
My Makefile-fu fails me on producing a cross-product or double
iteration for languages and man pages. Until that is solved
each man page is explicitly built. No big deal but it doesn't
look elegant in the Makefile. Languages will be picked
up automatically if they are found in man-po, man-po/top or
man-po/ps
The README describes the three-step process for translating
the files, incase I forget or someone else wants to update them.
When fileutils with stream error checking was borrowed
from GNU lib, an omission was also propagated where an
errno of EPIPE wouldn't be preserved in close_stream()
making a test for EPIPE in close_stdout() meaningless.
This patch corrects such oversight so that an errno of
EPIPE no longer produces 'write error' at program end.
( gnulib provides for optionally ignoring EPIPE, but )
( if a program chooses to ignore it, then their code )
( appears to suffer from this close_stream oversight )

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.

For portability, check for error.h during configure and define
HAVE_ERROR_H accordingly.
If this header is not available, emulate the functionality of error()
from glibc with an inline wrapper in include/c.h.
For portability, check for stdio_ext.h during configure and define
HAVE_STDIO_EXT_H accordingly.
If the current system does not provide this header, use a fallback for
__fpending(). This definition will not work on all systems as it relies
on internal data structures of libc. A more portable solution should be
preferred, for example by using gnulib.
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!

Even as conservative project as coreutils has switched to xz distributions so
neither should we have any reason to use gz and waste space & bandwidth.

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.
The utility library is for functions which are shared in commands,
but that does not belong to libproc-ng. The first function is a
wrapper for strtol that performs error checking, and exists if such
happen.
