ca4a09c432 library: memory and vmstat API changes
Created new set of functions for meminfo related calls. Liked the
format of that better so changed vmstat around so the look similar.
Missed the makefile change for uptime so added it in now.

d7932b9a13 library: uptime API changes
Removed the printf_uptime, binaries can do printf easily enough.
sprint_uptime split into two as there wasn't a lot of common
code
 sprint_uptime(): old style uptime line
 sprint_uptime_short(): short new style "uptime -p"

Hertz_hack needed this, no sane system uses the code (I think)
so just assume 100 like we do in FreeBSD.

a410e236ab library: sysstat and vmstat api changes
Use the standard libc declarations.
For protecting the headers for C++ procps used to have its
own defines, this change makes them use the standard libc ones.

getstat() -> procps_stat_*
vminfo() -> procps_vmstat_*
These two components of the library now use the newer version of
the API with less exposed global variables. The old methods are
there for now.

9e85c147b2 build-sys: tweak to prevent dirty tree with every make
Please let's stop the nls translation insanity. With a
one time push we can eliminate the dirty tree syndrome
which surfaces with every local build. Later, before a
release, the translations can be updated in final form
then pushed just 1 more time to the gitlab repository.

I'm tired of having to always re-issue this request in
order to circumvent the problem and thus prevent a too
broad commit (not to mention some nasty side effects).

caeebdc71f ps: exploit the simplified library interface for wchan
This patch was made necessary by those library changes
in support of recently revised/simplified wchan logic.

In addition, this commit eliminates a broken alternate
'namelist' provision which was intended to allow users
to specify a System.map file to be used in translating
addresses into function names. But, the real effect of
the now defunct 'N' and '-n' options was to indirectly
force addresses (not names) to be displayed since such
user named map files could not be successfully parsed.

Besides when the required FRAME_POINTER kconfig option
is absent there is no address to translate and when it
is present /proc/PID/wchan is already translated. Thus
an alternate mapping is unnecessary and inappropriate.

[ we'll forgive POSIX for documenting '-n  namelist' ]

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.

0557504f9c library: add support for displaying LXC container name
This commit adds a lxc container name to every proc_t.
If a process is not running in a container, then a '-'
will be provided, making such a field always sortable.

Unlike other proc_t character pointers, lxc containers
will find many duplicate shared values. So rather than
strdup 'em (with a later free required upon reuse), we
try to keep track of those already seen and share that
address among all tasks running within each container.

We rely on the lines in the task's cgroup subdirectory
which may initially seem somewhat unsophisticated. But
the lxc library itself uses a similar approach when it
is called to list active containers. In that case, the
/proc/net/unix directory is parsed for the '/lxc' eye-
catcher, with potential complications from hashed path
and names that are too long (something we don't face).

[ too bad docker abandoned lxc - our commit won't do ]
[ anything for the users of those kind of containers ]

96bce4e11e library: address memory aberration with LXC containers
Under a lxc container, the /proc/meminfo 'MemFree' and
'MemAvailable' amounts will be equal, unless memory is
being limited via cgroups in which case 'MemAvailable'
could exceed that for 'MemTotal'. And when a container
has been nested, there exist additional memory quirks.

A program might then display used or available amounts
greater than total memory (assuming unsigned honored),
or negative values (should a signed cast be employed).

This anomaly primarily impacted the top and free pgms.
Thus, two simple sanity checks have been introduced to
avoid any illogical kb_main_available or kb_main_used.

( Busybox top & free also display anomalous although )
( different results when running in a lxc container. )

2753a8f3db Merge branch 'fix_parallel_build' into 'master'
build-sys: use proper dependencies on libproc.la

Use `LDADD` or `*_LDADD` instead of `AM_LDFLAGS` to refer to `libproc.la`.

This is recommended in the automake manual:
http://www.gnu.org/software/automake/manual/html_node/Linking.html

Before this commit, parallel builds may break, as there is no explicit dependency to ensure the library is built before the binaries that try to link to it.

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`.

e40b0060c2 tests: slabinfo should not be too strict about slab names
Before this commit, the test checking `vmstat -m` (slabinfo) output uses
a fairly strict regular expression that only allows alphanumeric
characters and a few exceptions such as "_", "-", "(" and ")".

However, recent kernels use a wider range of characters, such as ">".
For instance, see this Linux commit which creates a "page->ptl" slab:
  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/mm/memory.c?id=b35f1819acd9243a3ff7ad25b1fa8bd6bfe80fb2#n4283

Other patches for reporting slab usage per memcg include the names of
the cgroup in the slabinfo output, which can include additional
characters and use dots for abbreviation.

The check should not be so string, instead it could simply look for a
chain of non-whitespace characters and that should be enough.

Tested that `make check` is still working, including in some of the
environments where features that enable the additional slabinfo names.

af6e264b46 tests: fix regexp in ps_sched_batch.exp to match in first line
The current regexp checks for a \s+ in the beginning, however that will
only match if there is a \n in the `ps` output before test-schedbatch,
but that will not happen if test-schedbatch is the first process in the
list, which happens if the PID of test-schedbatch is low enough to bring
it up in the sorted list.

Fix it by enabling newline-sensitive matching with (?n) which then
allows using ^ and $ anchors in the regexp (including an optional \r
introduced by expect.) Matching the end of line also improves checking
that the last field matches 18 exactly and not something like 181, etc.

Tested that `make check` does not break and also fixed the flakiness
seen in an environment with few processes running under the test user
which made the issue more frequent.

e981f2bbd2 tests: do not mark ps_sched_batch.exp as untested
Right now the test case is both testing it (expect_pass "$test") and
marking it as untested (untested "$test"), it should do either one or
the other, so stop marking it as untested.

Before this change, these lines appear in testsuite/ps.log or the output
of `make check RUNTESTFLAGS="--all"`:

  PASS: ps SCHED_BATCH scheduler
  UNTESTED: ps SCHED_BATCH scheduler

Note that the second line is confusing, it's implying that the test is
untested, right after having tested it and indicated it passes.

After this change, only the first line will appear.

Tested that both `make check` and `make distcheck` continue working with
this commit.
