We have had shell functions in ltmain.in for a few years without
complaint now, and recently a few more have crept in. Make a
start at refactoring the code with shell functions, and
standardising on option parsing style:
* config/ltmain.in (func_echo, func_verbose, func_error)
(func_fatal_error, func_fatal_help, func_missing_arg)
(func_version, func_usage, func_help): Boiler plate shell
functions mostly copied from libtoolize.in. Changed *lots* of
shell snippets to call these functions as appropriate, rather than
inlining the same code over and over.
(func_config, func_features, func_enable_tag, func_mode_help):
Factored out from the shared option parsing loop. Write a new
shared option parser based on the one in libtoolize.in.
(func_check_version_match): Factored out from global scope.
(func_mode_compile, func_mode_execute, func_mode_finish)
(func_mode_install, func_mode_link, func_mode_uninstall): Break
each of the top level mode handlers out into a function. Adjust
main loop.
(modename, prevopt, prev, optarg, show_help): Removed in the
course of cleaning up the shared option parser.
(opt_duplicate_deps): Use `:' and `false' instead of `yes' and `',

My thanks to Alexandre Duret-Lutz <adl@gnu.org> for the insight
required to write this changeset -- especially that ltmain.sh is
the same on any machine for a given release, which I hadn't
noticed for some bizarre reason: It turns out that generating
distributed files from configure causes no end of hassle, as
evidenced by the many patches I've generated over the last few
days to try and get the dist and distcheck make rules to work.
Instead of all that hair, we now simply generate our distributed
files (now including ltmain.sh) with make rules -- and since
automake creates make variables for all AC_SUBSTs, that is really
easy. The code looks a lot more like automake and autoconf
Makefile.ams now, and doesn't have all the rough edges the earlier
hacky solution suffered from. We still generate libtool from
config.status, but that is not a distributed file, and doesn't
break the golden rule. Besides, there is way more going on there

* Makefile.am (edit): New common sed substitutions for files now
generated by make instead of config.status.

This pervasive changeset makes two intertwined deep changes to the
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
