build-sys: sensible errors when autogen.sh requirements are is missing
<quote="Jim">
I tested the build on several "new" linux installs that didn't yet have any
development tools beyond gcc. On those systems the following error messages
were received:
./autogen.sh: line 46: libtoolize: command not found
./autogen.sh: line 47: test: =: unary operator expected
</quote>
This commit also removes few unnecessary empty lines, and makes all shell
variables to be wrote in caps & quoted properly.

build-sys: use AC_HEADER_STDBOOL in configure.ac
The AC_CHECK_HEADER_STDBOOL, which was used earlier, requires
autoconf 2.68 (2010-09-22), without great functional benefit in
comparison AC_HEADER_STDBOOL. The only thing newer macro does is
a problem for many user who has older autoconf in use.

build-sys: add contrib directory

alternative ps & w, and and broken utmp examination / printing

autotools where re-introduced.

build-sys: take autotools in use again
This will revert change at Oct 2002 when autotools support was
removed.
Unlike before the package developers are expected to use
./autogen.sh to generate ./configure script, and run make after
that. The build system is also able to create, with make dist, a
tar ball release which compiles correctly, and has files which
seemed to be important to have.
The patch removes few unnecessary files, but no everything. Files
procps.lsm and procps.spec in git repository are useless as is,
but I left them lying around for someone who can make more
justified call about removal of them.
Last, but not least package version number is set 3.3.0 to
distinct this procps from the sourceforge's upstream procps.
Please notice that libproc relese is kept as 3.2.8.

Read the system boot time from /proc instead of computing
Read the time of system boot from /proc/stat (entry: btime) instead
of computing it as the difference between the current time and the
uptime. This is the only way to get a consistent result which won't
possibly change from one run to the next.
The problems with the original code were:
* Both the current time and the uptime are rounded down to the second,
but the system doesn't boot on an integer second value so they do not
tick at the same moment. Thus, the rounding errors can cause a one
second difference from one run to the next.
* We can't read the uptime and the current time at the exact same moment
anyway, so the time difference we compute is bound to be inaccurate.
