modern libtool

[Eric Blake]

This patch keeps libltdl in subproject mode (more libtool fixes are needed 
before we can take the leap to nonrecursive mode); it is mainly to silence a 
bootstrap warning that we are using an obsolete API.  I'm applying it now.

* configure.ac (LT_PREREQ): Require bleeding-edge libtool.
(LT_WITH_LTDL): Delete, now that it is obsolete.
(LTDL_INIT): Use new libtool macro.
