[MPlayer-dev-eng] supported ALSA versions

[Diego Biurrun]

I looked into the baroque ALSA check in configure and noticed that we
support ALSA versions from 2000 (last 0.5 release) and 2003 (last 0.9
release).  While maintaining compatibility and such is all nice and
great a decade sounds like the timeframe when one can safely eliminate
cruft.

Am I overlooking something non-obvious about systems without ALSA
versions from at least 2003 (first 1.0 release)?
