03437d7dd3 A locale-independent strtod
There is a need in some utilities to have a way of accepting both
types of decimal points "." and ",". The only way seems to be to
rebuild strtod().

This new function will accept "123.456" and "123,456" as 123.456
and considers them the same number. It means we lose thousands
separator, but this is rarely used.

test scripts are added to check the function returns the proper
values. There was simpler predecessor that got stuck on negative
0 or -0.123 which these tests flushed out.

f65121ef74 kill: split out from skill/snice
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.

a61f78d6e0 library: rework namespace calls
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.

7e6a371d8a library: implement task/thread support via the new api
This commit is the culmination of efforts to modernize
the library api. It should be treated as a first blush
attempt, especially since I have absolutely no library
design experience. But I did have a very strong desire
to lessen the new library's impact on the top program.

Under this new api, a 'stack' is the equivalent of the
old proc_t. It can be seen as a variable length record
whose contents & order is under complete user control.

That initial stack/record configuration is established
at procps_pids_new() time and will probably serve most
program needs. But, a dynamic & demanding program like
top will later change a stack via procps_pids_reset().

For programs like top & ps, procps_pids_reap() will be
the function that will retrieve all tasks and threads.

Any program that needs to filter / select only certain
processes or users have available other functions that
can be used: procps_pids_stacks_alloc, fill & dealloc.

This implementation attempts to maximize that existing
proven libprocps code base. As we gain more experience
such actual code can be migrated into the pids.c file.

5686cc5cb5 build-sys: include .version in EXTRA_DIST
.version is created in the top_srdir which when building normally
doesn't present a problem. When make distcheck is run, the source
directory is made read-only and it fails with permission denied.

The version of misc/git-version-gen is old and is missing the
instruction to add .version to EXTRA_DIST. This commit does just
that.

make distcheck now passes.

e445f7e6c5 library: Update diskstat API
The calls for reading diskstat have been moved out of
sysinfo and into new files diskstat.[ch] These new
library calls follow the standard pattern for the
new libprocps.

vmstat is updated to use the new API and also got
the weighted IO time added.

vmstat -p previously would only show partitions, not
disks. There does not appear to be any good reason to
artifically deny a user to use this command on a disk,
rather than a partition so this restriction was lifted.

I also realised using int for devid means you can send
the library negative numbers, the index uses unsigned int.
Other similiar calls will need to be fixed too.

56399212c8 library: Remove signal name from library
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

6b8dc5511f library: refactor and rely on modern kernels for wchan
Several Debian based distributions were recently found
to have omitted a kernel configuration option that had
the effect of rendering /proc/#/stat and /proc/#/wchan
useless for providing any 'sleeping in function' info.

That problem also prompted a reevaluation of the whole
approach to wchan matters which had grown increasingly
complex as our library evolved over the last 13 years.

The net result was a decision to rely on /proc/#/wchan
which arrived along with the 2.5 kernel. This then let
us vastly simplify the internal code plus the external
interface which will benefit both the top and ps pgms.

5cabea8409 build-sys: use proper dependencies on libproc.la
Use LDADD or *_LDADD instead of AM_LDFLAGS to refer to libproc.la.
Otherwise, parallel builds will break as there is no explicit dependency
to ensure the library is built before the binaries that try to link to
it.

v2: Added empty rules lib_test_*_LDADD to remove the dependency on
libproc which is not used by the lib/test_* binaries.

Tested by running `make -jNN` repeatedly for different levels of
parallelism to ensure the build works. Also checked that `make check`
and `make distcheck` still work as expected. Also made sure that a
parallel make invocation works with `make -j distcheck`.

430b559ba2 build-sys: install binaries in bindir (get rid of usrbin_execdir)
The "usrbin_execdir" hack meant to install some binaries in /bin and
others in /usr/bin. However:

- It is very inflexible: not much control on the final directory name
  and it is not possible to get rid of the usr/bin suffix without
  patching the build system.

- It is hard to use: it requires configure to receive --exec_prefix=/
  and other settings do not make much sense. It is not very obvious that
  that setting needs to be passed and it takes a while to figure it out.

- It produces garbage with the default setup: the default prefix of
  /usr/local ends up installing the binaries under /usr/local/usr/bin
  which does not make any sense.

Furthermore, the requirement to split binaries in /bin and /usr/bin is
not that strong since some distributions adopted the /usr merge and so
would agree to just deploy all binaries to /usr/bin directly.

Distributions that would still like to split /bin from /usr/bin should
actually move binaries such as `ps` and `kill` to /bin after the install
of procps-ng is complete. After all, they are the ones responsible for
determining what are the binaries that need to be in the root partition
and that list depends on their early boot init scripts, so it is
possible that the list must be augmented with other binaries from this
package.

Therefore, I propose here to get rid of that hack and simply install all
the binaries to bindir instead, which solves the problems described
above and simplifies the build and install of procps-ng.

Tested that it builds and both `make check` and `make distcheck` work.

Tested that `make install` works and produces the expected tree, the
only difference being the absence of the bogus /usr/local/usr/bin
directory and now all binaries are merged into /usr/local/bin as
expected.

0f8f760307 Manpage translations in Makefiles
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.
