Reported by Noah Mish <noah@cs.caltech.edu>
operation of libtool (neither would work alone). First, there is
a new feature that allows libraries to preopen modules. This
entails a backwards incompatible change to the libltdl API for
separating out the preloaded symbol lists by owner. Second, in
the tradition of "eating our own dogfood", libltdl now preloads
its own dlloaders. The internal API for dlloaders has also had to
change in a backwards incompatible way in support of the new
library preloading feature. If you don't use preloaded libraries,
you needn't change your project sources, though you will need to
recompile against the new libltdl. The API changes are mostly
confined to dlloaders, so you probably needn't worry about those
(unless you have written a custom loader that you want libltdl to
use):
* configure.ac (AC_CONFIG_FILES): Add libltdl/loaders/Makefile.
* libltdl/configure.ac (AC_CONFIG_FILES): Add loaders/Makefile.

Makefile rules, and to give the loaders themselves names that are
unique in the first few characters.
* libtoolize.in (func_copy_all_files): Copy recursively to pick up
the loaders directory contents.
* libltdl/loaders/Makefile.am: New file. Move module building
rules to here...

(symlist_chain): ...a new structure which maps lists of preloaded
symbols from the object that loads them.
(lt_dlpreload_open): New function to automatically open all
preloaded modules belonging to a named object (ORIGINATOR).

dlloader loading.

symbols to bootstrap the loader chain.
(lt_dlinit): Load the preopen dlloader manually, and then use it
to load any other preloaded dlloaders.
(lt_dlloader_add): Simplify parameter list. Populate new
fields. Chain new loaders according to priority field.
* libltdl/ltdl.h (lt_dlsymlist): Add a new originator field.
(lt_dlpreload_callback_func): Type of a callback for automatic

loading libraries/apis rather that stopping when an acceptable one
is discovered.
(LT_DLLOADERS): New variable for holding dlloaders that can be
preloaded.
