visibility set according to the underlying implementation.
Here, we add lt_dlopenadvise() to allow callers to request,
among other things, local or global symbol visibility from the
underlying dlloader:
* libltdl/ltdl.c (LT_DLRESIDENT_FLAG): Removed.
(LT_DLIS_RESIDENT): Use public is_resident info field.
(LT_DLIS_SYMLOCAL, LT_DLIS_SYMGLOBAL): New macros to test for
module symbol visibility status.
(tryall_dlopen): If vtable->module_open() was able to act on
either is_symlocal or is_symglobal hints, store that in
the handle flags.
(lt_dlopenadvise): New function that works like lt_dlopen(),
but accepts an advise type to determine whether to ask
dlloaders to change default symbol visibility.
(lt_dlopen, lt_dlopenext): Just call lt_dlopenadvise() with
the correct parameters.
(lt_dladvise_init, lt_dladvise_destroy): New functions to
initialize and destroy an advise type hint.
(lt_dladvise_ext, lt_dladvise_resident, lt_dladvise_local)
(lt_dladvise_global): Set hints on an advise type.
(openadvise): Factored out of lt_dlopenadvise.
(has_library_ext): Factored out of lt_dlopenadvise.
* libltdl/ltdl.h: Declare all of the above.
(lt_dlinfo): New fields for advise hints.
* libltdl/libltdl/lt_dlloader.h (lt_module_open): Add a new
advise parameter. Adjust all callers.
(lt_dladvise): New opaque type for advise hints.
* libltdl/libltdl/lt__private.h (lt__advise): Declare
contents of opaque lt_dladvise type.
* libltdl/libltdl/lt_error.h (CONFLICTING_FLAGS): New error
for attempts to have local and global symbol visibility at the
same time.
* libltdl/loaders/dld_link.c, libltdl/loaders/dyld.c,
libltdl/loaders/load_add_on.c, libltdl/loaders/loadlibrary.c,
libltdl/loaders/preopen.c, libltdl/loaders/shl_load.c: Adjust.
* libltdl/loaders/dlopen.c (RTLD_LOCAL, RTLD_GLOBAL): Try to
define these symbols if the system has equivalents.
(vmopen): If unable to act on a caller request to set symbol
visibility, then unset the relevant hints in the advise type.
* tests/lt_dladvise.at: New tests for the above.
* doc/libtool.texi (Libltdl Interface): Updated.
* NEWS: Updated.
instead of SYSTEM_ARGZ_IS_BROKEN.
* libltdl/m4/argz.m4 (gl_FUNC_ARGZ): Ditto. Also, minor
stylistic improvements.

in same mechanism system argz.h would have.
* libltdl/libltdl/lt__glibc.h: also detect if
SYSTEM_ARGZ_IS_BROKEN when determining whether to re#def
argz* functions.
* libltdl/m4/argz.m4 (gl_FUNC_ARGZ): add new test to check
if $host's argz facilities are known bad. Err on the side
of caution if cross-compiling.
of `inherited_linker_flags' entries from multiple deplibs, by
adding $new_inherited_linker_flags only once, only in link pass.
* tests/inherited_flags: Amend test to expose this.
* NEWS: Adjust: kill one regression, but add note about the
feature new in 1.9b.

write to stdout
(func_mode_link): move cwrapper source code generation from

* Makefile.am ($(srcdir)/libltdl/Makefile.am): Do not depend
upon the exact text of the copyright header, just copy until
the marker line. Remove the marker lines in the output, and
adjust the description for subpackage setup.

* libltdl/config/ltmain.m4sh (func_mode_link): Avoid grepping a
nonexistent file if using reloadable objects. Do not create a
linker script nor a linker input file if no objects are passed.
Apply export_symbols_regex in case the command line length is
exceeded.
<compiler_needs_object>: New tag variable. Default to `no'.
(_LT_LINKER_SHLIBS) [ linux ]: Set it to yes for Sun C 5.9.
(_LT_LANG_CXX_CONFIG): Also default it to `no'.
[ linux ]: Set it to `yes' for Sun C++ 5.9.
* libltdl/config/ltmain.m4sh (func_mode_link): If we link
no objects but only convenience archives into a library,
force expansion if `compiler_needs_object' is yes.
For creating a linker input filelist due to long cmdline,
extract the first object if `compiler_needs_object' is yes.
* doc/libtool.texi (libtool script contents): Document it.

On Tru64 5.1, const relocations do not work well. Omit the
const here. Fixes failure of demo-make after demo-shared with
link editor error `seg_info_ptr: Couldnt find a seg type 2'.
<whole_archive_flag_spec>: For Sun C/C++ 5.9, do not add
/dev/null as dummy object, it fails with GNU ld version
2.16.91.0.7-amd-sles9. Report by Terry D. Dontje.

Use `${wl}' instead of `-Wl,', for consistency.
