an array of symbol name vs. address, and adding the originator as
the first symbol but with a NULL address:
* config/ltmain.in (func_extract_dlsyms): Store originator as a
NULL address symbol.
* libltdl/ltdl.h (lt_dlsymbol): Removed.
(lt_dlsymlist): Remove originator field.

internal lt__handle type.

* NEWS: Updated.
`loaders' list management into a new SList ADT. In the process,
the API for writing loaders is a little cleaner, so all the
existing loaders were tweaked to take advantage of that:
* libltdl/slist.h, libltdl/slist.c: New files implementing a
generic singly linked list container ADT. The ADT is purely
internal, and none of its API's are visible from an installed
libltdl.
* libltdl/lt_dlloader.h (lt_dlloader): Removed next field again
:-) Renamed to lt_dlvtable for API. Changed all callers.
(lt_dlloader_get): New function to turn an lt_dlloader into its
associated lt_dlvtable.
(lt_dlloader_add): Removed unused data parameter. The caller
data belongs to (and is set by) the loader itself, not the
loader's client. Changed all callers.
(lt_dlloader_name, lt_dlloader_data): Removed. Use
lt_dlloader_get instead!
* libltdl/lt__private.h: Include slist.h.
(lt__alloc_die_callback): Add missing LT_SCOPE to declaration.
(lt_dlhandle_struct): Use lt_dlvtable instead of opaque
lt_dlloader.

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.
* libltdl/loaders: New directory for module loaders, to simplify
Makefile rules, and to give the loaders themselves names that are
unique in the first few characters.

the loaders directory contents.
* libltdl/loaders/Makefile.am: New file. Move module building
rules to here...
* libltdl/Makefile.am: ...from here.

appropriately for each library.

Applications should assume that the native dlopen is NOT

of the portability layer, these functions no longer use libltdl
memory management API.
