-Repocopy devel/libtool15 -> libtool22 and libltdl15 -> libltdl22. -Update libtool and libltdl to 2.2.6a. -Remove devel/libtool15 and devel/libltdl15. -Fix ports build with libtool22/libltdl22. -Bump ports that depend on libltdl22 due to shared library version change. -Explain what to do update in the UPDATING.

It has been tested with GNOME2, XFCE4, KDE3, KDE4 and other many wm/desktop
and applications in the runtime.

Update to 1.5.24

* Correctly patch devel/libltdl15 with the upstream hack to   prevent eg: gnucash from taking several aeons to start up.

* Hack around the fact that the above then wants to call various
  autotools to rebuild parts of the build infrastructure which,
  depending on the ports installed can cause things to fail in
  weird and wonderful ways.

Remove massive overheads from loading programs that use many libtool-generated shared libraries by forcing libtool into understanding that FreeBSD can correctly handle shared library dependencies.

This code already exists in the libtool CVS repository but without knowing
the release schedule (if any) for a new libtool 1.5.x series, and the
exceptional performance gains (gnucash for example uses 122 shared libraries
and with things rebuilt now starts up in ~10 seconds as opposed to 15
*minutes*).  Further, a number of people have assisted in extensive testing
of this code in a series of different environments, so I am therefore
adding this patch to the tree.

Conversion to a single libtool environment.

Anchor MASTERDIR correctly

Switch over to versioned devel/libltdl15 (from devel/libltdl) after repo-copy.

Avoid libtool vs libltdl friendly fire in the package tree.

Missed in last commit.  Move libltdl's pkg-* to a saner place.

Upgrade to libtool 1.5 after repo-copy.

libtool uber-patch

* kill devel/libtool and move to devel/libtool13, upgrading to 1.3.5
* upgrade repo-copied devel/libtool14 to 1.4.3
* break out libltdl into its own separate port
* move to version-numbered binaries/scripts (ie: there is *no* 'libtool'
  any more -- USE_LIBTOOL and USE_LIBTOOL_VER are your friends)
