Approved and reviewed by:       marcus

Say hello to the new "net-mgmt" category.  There are probably more
ports that belong here than the ones I have identified and moved in
this, first, pass.

Fix that and bump PORTREVISION yet again.

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)

Approved by:    portmgr (kris) - for the bsd.port.mk hooks

De-pkg-comment.

Mark IGNORE with $OSVERSION >= 500100.
Backporting 4.x for latest OpenSSL suite will take some timeslots, but
I'll not work for it.

Release maintainership to ports@ until now.  If there is no maintainer
appeared, I'll remove this port some time after.
