Subject: [PATCH] configure.ac: improve alsa handling
Three improvements:
1) "--enable-alsa" or "--disable-alsa" caused a warning about an
unsupported configure option, because AC_ARG_ENABLE was not used.
2) If alsa was disabled, the "Have ALSA" item in the summary would print
an empty string instead of "no".
3) If "--enable-alsa" was passed to configure, but the headers were not
found, configure would still succeed (with alsa disabled). It's better
to fail and abort configure if a feature that was explicitly requested
can't be enabled.
