3388f65c03 build-sys: correct all Makefile.am files for LOCALEDIR, etc
Some of the latest changes to Makefile.am files are missing.

This patch restores the LOCALEDIR variable, among others,
and dispenses with the include directives in the ps/ and top/
subdirectories since they're no longer needed.

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.

2983b30523 Renaming libprocfs to libprocps
The library used to be called libprocps but it was renamed to make sure
there was only one. However the formatting of the library SONAME has
changed so there cannot be any confusion.

libprocps makes it clear that its a library from this project and not a
set of functions directly on the filesystem.

fe82a3246a ps: add build option to disable ps option warning
Slackware seems to have this patch, while it is not in use(?) Well,
the upstream procps-ng allows one to disable warnings if that is
wanted. After all having this sort of 'feature' does not cost much,
while lacking it might annoy someone.

38763ede40 Rename library and use proper versioning
Previously the version of libproc always tracked the version of procps.
This doesn't work when other non-procps programs link to the library as
they are always playing catch up.

This change makes the library version independent of the procps version.
It will only be incremented when needed.

c3a1239efe library: once again properly ignore a final empty cgroup
Commit a5881b5a4e, addressing
command lines with a trailing space, produced an undesirable
side effect in the fill_cgroup_cvt() function.

This patch restores correct cgroup behavior while still
producing command lines with no trailing space.

a5881b5a4e library: create cmdlines consistently with no trailing space
When PROC_FILLARG was used (invoking file2strvec)
command lines contained no trailing space.

When PROC_EDITCMDLCVT was used (invoking read_unvectored)
command lines contained a trailing space.

Now both routes to a cmdline act the same -- no trailing space.

ed59472307 library: provide for huge cmdlines, like old libproc
The CodingStyle document suggests programs should allow for
cmdlines of at least 128k.  Only the ps program can display
such a cmdline, and only with multiple -w switches.

The library function file2strvec can essentially return
a cmdline of unlimited length.  However, the library function
fill_cmdline_cvt used an arbitrary upper limit of 2048 for
buffers automatically allocated on the stack.

This patch raises the fill_cmdline_cvt upper limit to 128k via
dymaically acquired utility buffers ensured by the openproc
function.

It also makes indentation consistent in the openproc function.

827334870d library: exploit enhanced library memory allocation provisions

7126cc4491 library: expanded/generalized memory allocation provisions
A callback provision in the form of xalloc_err_handler
(of type message_fn) was added to the alloc module.

This change allowed a program like top, who alters the
termios structure, to override the default fprint(stderr...)
behavior in the event of an error.

The new function xstrdup was also added for symmetry.

13ce6ebdf0 Use 7 cpu numbers not 4 for Hertz Hack
For the small number of devices that we cannot get Hertz out of ELF
notes but the cpu numbers make sense (ie not kFreeBSD) there is a hack
by using the CPU numbers. The problem is there was 4 numbers, now there
are 7. This fixes the hack by adding all 7 to get a more correct number.

This is from Debian patch sysinfo_7_numbers

a5750100a0 Fix Hertz calculation for FreeBSD
FreeBSD has no good way of finding the Hertz value. ELF notes don't
work, you can't find it in a function and even asm/params.h does
not have it.  Lucky for us, it is always 100.

Based upon Debian patch patch sysinfo_kfreebsd_hertz by Petr Salinger

Caution, 460331 has lots of overlapping bugs all around the Hertz
