build: upgrade build system

- add .gitignore files
- replace outdated autoconf macros by new constructs, including autogen.sh
- and use AC_CONFIG_MACRO_DIR as suggested by libtool2:

libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and
libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
