* demo/Makefile.am: renamed hell.debug to hell.static
(we're demonstrating static linking, not debugging)
* tests/demo*: ditto
* doc/libtool.texi (libltdl): documented new lt_dlopen(NULL)
feature
* libltdl/acconfig.h: required for config.h
* libltdl/configure.in: use config.h
* libltdl/ltdl.c: use config.h, support lt_dlopen(NULL)
(returns a handle for the program itself)
* ltconfig.in: minor reformatting
* ltmain.in: in lt_preloaded_symbols always define
the program's symbols first, for -export-dynamic list all
program symbols together, -export-symbols was broken for
programs, minor reformatting
* mdemo/Makefile.am: renamed mdemo.debug to mdemo.static
* tests/mdemo*: ditto, mdemo.test was completely broken
* tests/mdemo-shared.test, tests/mdemo-static.test: ditto
* tests/Makefile.am: ditto
* doc/libtool.texi: document them
* demo/Makefile.am, mdemo/Makefile.am (@STATIC@): do not use
-static unconditionally, it can't work with --disable-static
* demo/configure.in, mdemo/configure.in: check whether libtool was
configured to build static libraries and, if not, set STATIC to an
empty string
