configure.ac: fail when ALSA is enabled but not found
This patch adds a small autoconf M4 library which deals with
auto-detected features. The default for those features is "auto",
which is like the old default: if the library is present on the
system, enable the feature, disable otherwise. If the user explicitly
enables that feature (--enable-alsa), and the library is not present,
configure must fail, because it cannot fulfill the request.
