NOTE: api has changed (different major number on library). all other
libao packages need updating as well
changes:
* New API is not compatible with programs that used the old API.
* Default driver detection works correctly.
* Compilation fixes for the BSDs and Solaris.
* OSS driver no longer freezes on systems using the OSS emulation
layer of ALSA when the dsp device is in use by another device.
* Configuration file support has been added. See the libao.conf(5)
man page for details.
<naddy@openbsd.org> in private communication; a patch against a memory
leak in the wav file writer, forwarded from the vorbis-dev list by
Jeremy C. Reed; also use pkgsrc libtool instead of included one, and
don't depend on esd anymore.
Bump version to 0.6.0nb1.
