Log message:
        Backported the following patches from the development branch:
        
        Based on a patch from Marius Vollmer <address@hidden>:
        * NEWS: updated.
        * ltdl.m4 (AC_LIB_LTDL): Check for unistd.h.
        * libltdl/ltdl.c: Include unistd.h if it exists.
        (LTDL_SEARCHPATH_VAR): Macro to prevent hardcoding
        "LTDL_LIBRARY_PATH".
        (LTDL_ARCHIVE_EXT): Macro to prevent hardcoding ".la".
        (archive_ext): Have only one copy of ".la" in the readonly
        segment of the compiled library.
        (find_handle_callback): Don't bother trying to dlopen the file if
        it doesn't exist.
        (find_handle): Don't bother searching for files if no search_path
        was supplied.
        (file_not_found): A new function to determine whether the last
        error was due to a file not found condition.
        (try_dlopen): Renamed from lt_dlopen() and changed to have the
        same footprint as tryall_dlopen.  This involved a minor rewrite of
        much of the internals of this function.
        (lt_dlopen): A new function wrapped arounf try_dlopen().
        (lt_dlopenext): If a file already has a suitable extension, don't
        bother adding additional extensions and trying to open those.
        Tidy up the rest of the code to prevent continued searching with
        an eventual FILE_NOT_FOUND when a genuine failure earlier in the
        search process could be legitimately reported.
        
        * libltdl/ltdl.c (argz_create_sep): Don't forget to include the
        terminating '0' when counting argz_len.
        (argz_create_sep): When canonicalizing argz, don't forget to copy
        the terminating '0', incase canonicalization has shortened argz.
        (argz_stringify): Don't covert the final '0' to a separator.
        
        * libltdl/ltdl.c (lt_dlhandle_next): Now we can loop through all
        loaded module handles as originally intended.
        
        * libltdl/ltdl.c (lt_dlseterror): Oops.  This never worked
        either, due to a pair of typos.  Now fixed.
        
        * libltdl/ltdl.c (N_ELEMENTS):  Deleted.  How come nobody noticed
        there was no way this could have ever worked?
        (lt_dlcaller_set_data): Now that valid caller_ids must be
        non-zero, allocate an addition entry in the caller_data vector and
        use a zero valued key as the end marker.
        (lt_dlcaller_get_data): Iterate up to the end marker in one pass.
        
        * libltdl/ltdl.c (lt_dlcaller_register): Caller ids are allocated
        starting from value `1', so that clients can use a value of zero
        to indicate that libltdl has not yet initialised.
        
        * libltdl/ltdl.c (find_file_callback): Fix a multiple free()
        bug.
        (tryall_dlopen_module): Remove some unused variables.
        
        * libltdl/ltdl.c (lt_dlinsertsearchdir): Calculate the address
        of the end of user_search_path correctly.
        
        * libltdl/ltdl.c (rpl_argz_stringify): New fallback implementation.
        * ltdl.m4 (AC_LTDL_FUNC_ARGZ):  Test for argz_stringify in libc.
        * libltdl/ltdl.c (lt_argz_insertinorder): Renamed from
        lt_argz_insert to make room for...
        (lt_argz_insert): Wraps argz_insert with libltdl error handling.
        (lt_dlpath_insertdir): Insert new path elements into an
        argzized path.
        (lt_dlinsertsearchdir): New function to insert new search
        directories anywhere into user_search_path using the above.
        (lt_dladdsearchdir): Rewritten to use lt_dlpath_insertdir.
        * libltdl/ltdl.h (lt_dlinsertsearchdir): Prototype for export.
        * doc/libtool.texi (Libltdl interface): Document it.
