Checking for linux kernel version 2.7.0 is meaningless now when 3.0.0
is out.

Clean the global list of symbols contain only functions and variables which
are being called from library. The removed symbols are internal for the
library, which means they can be changed without changes to programs using
the library. This clean up should help incoming libprocps clean up work.

On non-linux systems, uts.version provides the version of that
specific kernel (FreeBSD or Hurd version, for example) and not the
emulated procfs pseudo version.
On those systems we need to directly read /proc/version and parse the
string. This change replaces Debian patches gnu-kbsd-version and
complain_unmounted_proc patches.
procps automake defines restrict which means the binaries for procps
binaries compile. However external programs may not of defined
restrict which means they will not complie if they include files found
in /usr/include/proc.
Includes from libc6 use __restrict and if is good enough for
them, its good enough for us.
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.
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 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.
Re-enable signal number to name string, and other way around,
conversion after it broke at the time when long options where
introduced.

The function will convert a signal number string to a signal name, or
vice a verse. Return value is string, which is an function user is
expected to free after use.

Fix few compiler warnings. Some of these warnings appeared multiple
times, and the listing bellow is more about which sort of errors
where fixed.
devname.c:87:12: warning: comparison of integers of different signs: 'int' and 'unsigned long'
output.c:389:36: warning: passing 'char **const' to parameter of type 'const char *const restrict *' discards qualifiers in nested pointer types
output.c:611:31: warning: comparison of integers of different signs: 'const unsigned long' and 'int'
stacktrace.c:33:37: warning: unused parameter 'signum'

The devname.h requires readproc.h header which has dev_t. Unless
header is included the includes in program files must be in
correct order. I also added FIXME item to remind that for uid &
gid value int not correct data type but uid_t or gid_t from
pwd.h.

These xalloc functions are a private function for the library. If using
programs need them, then they should make their own error reporting or
use a common file.
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.
A patch from Slackware.

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.
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.
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.
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.
There were numerous library memory allocation inconsistencies.
Some were checked for failure and others were not.
All library source modules were modified to utilize the alloc.h
memory rouines which are consistent in dealing with errors.
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.
configure.ac now set to 3.3.1
vmstat -p has not worked for a long time, this applies Debian patch

Notice that contents of file library.map file are almost certainly
wrong as it is making everything exported.

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
Bug-Debian: http://bugs.debian.org/460331
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
Bug-Debian: http://bugs.debian.org/460331
Caution, 460331 has lots of overlapping bugs all around the Hertz
problem across many arches.
Suppresses a message about elf notes not found on non-Linux systems.
kFreeBSD systems, for one, don't have this so the message appears
every time you run a procps program otherwise.
