Port build system to non-recursive Automake.

All but toplevel Makefile.am are replaced with their non-recursive
counterparts. The generation of configure.in was removed (and thus
configure-{pre,post}.in are also removed) in favor of configure.ac
and m4 macros adding backend specific configure parts.

Version number is generated like in old build system.

There are still many things to improve, but for now there are no
immediate regressions. AUTOTOOLS-TODO contains a list of possible
improvements and fixes. AUTOTOOLS-TESTING contains what was tested
with current build system (configure flags, make options).
