Purge 3 outdated, old-and-busted, versions of automake as part of
ongoing cleanup to find sanity in the world.

Feature safe:   yes (surprisingly)

Autotools update.   Read ports/UPDATING 20100915 for details.

Approved by:    portmgr (for Mk/bsd.port.mk part)
Tested by:      Multiple -exp runs

Reassign the autotools-related ports to a new mailing list,
autotools@FreeBSD.org.  This is for individuals willing to put in
the hard work to generate patches and work with portmgr as we put
them through -exp runs and work through port breakage that they
create.  (A huge number of ports depend on these, so -exp runs are
required.)

Thanks to aDe@ for all the thankless work he's done over the years
to tame these beasts.

Hat:            portmgr

Update CONFIGURE_ARGS for how we pass CONFIGURE_TARGET to configure script.
Specifically, newer autoconf (> 2.13) has different semantic of the
configure target. In short, one should use --build=CONFIGURE_TARGET
instead of CONFIGURE_TARGET directly. Otherwise, you will get a warning
and the old semantic may be removed in later autoconf releases.

To workaround this issue, many ports hack the CONFIGURE_TARGET variable
so that it contains the ``--build='' prefix.

To solve this issue, under the fact that some ports still have
configure script generated by the old autoconf, we use runtime detection
in the do-configure target so that the proper argument can be used.

Changes to Mk/*:
 - Add runtime detection magic in bsd.port.mk

Conversion from (now defunct) autoconf-2.61 to autoconf-2.62

Tested by:      exp build run (erwin)

Do the PORTREVISION correctly (ie: old value + 1).  Sigh.  More coffee.
Or, perhaps, less beer.  Nah.  Unthinkable.

Still no functional changes.

Gently reminded by:     kris ;)

Fix PORTREVISION as per krismail.  These two did previously exist way
back when, so make them match up.  No functional changes.

Update to the autotools new world order.

Tested by:      numerous package build runs
Approved by:    portmgr
Thanks to:      des, kris, linimon, pav

Kill off automake18, switching to automake19.  Requiem Mors Pacem.

Other miscellaneous cleanups with info files

Long-overdue cosmetic cleanups.

Actually put in relevant symlinks to the versioned files in
${PREFIX}/bin to non-versioned files in ${PREFIX}/libexec/<autotool><ver>
so that the PATH magic in bsd.autotools.mk works correctly.

Expand %%X11BASE%% to the appropriate ${X11BASE} value in aclocal, so
that it can actually find files in ${X11BASE}/share/aclocal if need be.

Update to 1.8.5

Ensure that automake uses the correct version of autoconf

Update to 1.8.4

Fix one missed instance of pointing to the wrong location in generated
configuration files.

Say hello to autoconf 2.59 and automake 1.8(.3) after repo-copy.
It's likely to be a really bad idea to use these until they're hooked
into the new bsd.autotools.mk
