AC_INIT: add --runstatedir option to configure
http://lwn.net/Articles/436012/ documents that many distros
are now preferring to use /run rather than /var/run for
storage of pid files and other per-process temporary files
that must not be cleaned out during arbitrary TMPDIR sweeps.
As such, the GNU Coding Standards were recently changed to
recommend a new configure option to make it easy to choose
this directory at configure time. This patch adds support
for the option to all configure scripts built by autoconf.
* general.m4 (_AC_INIT_PARSE_ARGS): Add new directory option.
(_AC_INIT_HELP): Document it.
* doc/autoconf.texi (Installation Directory Variables): Document
new option.
(Site Defaults): Mention typical use within a distro.
* NEWS: Mention the addition.

+** Configure scripts now support a '--runstatedir' option, which
+ defaults to '${localstatedir}/run', and which can be used to place
+ per-process temporary runtime files (such as pid files) into '/run'
+ instead of '/var/run'.

** The use of the long-deprecated name 'configure.in' for the autoconf
input file now elicits a warning in the 'obsolete' category.
