Since the VAL macro now requires a 4th parameter, this
commit simply adds the 'info' context structure to it.
In some cases, that context structure needed to become
global, since it was referenced in multiple functions.

With this patch we've completed a progression toward a
standard approach to naming conventions which follows:
* Only functions will begin with that 'procps_' prefix
. ........................................... examples
. procps_vmstat_get ()
. procps_diskstats_select ()
- ----------------------------------------------------
* Exposed structures begin with the module/header name
. ........................................... examples
. struct pids_info
. struct stat_reaped
- ----------------------------------------------------
* Item enumerators begin like structs, but capitalized
. ........................................... examples
. VMSTAT_COMPACT_FAIL
. MEMINFO_DELTA_ACTIVE
[ slabinfo varies slightly due to some item variants ]
. SLABINFO_extra
. SLABS_SIZE_ACTIVE
. SLABNODE_OBJS_PER_SLAB
[ could cure with a prefix of SLABINFO, but too long ]
- ----------------------------------------------------
* Other enumerators work exactly like item enumerators
. ........................................... examples
. PIDS_SORT_ASCEND
. STAT_REAP_CPUS_AND_NODES
- ----------------------------------------------------
* Macros and constants begin just like the enumerators
. ........................................... examples
. #define SLABINFO_GET
. #define DISKSTATS_TYPE_DISK
- ----------------------------------------------------

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
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.

From original:
commit 9646f7cba4
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
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.

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

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!

commit fe75e26ab6

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,
