#4 audio ioctl decode patch

[Mattias Engdegård]

This patch adds decoding of audio ioctls to strace.
It is very handy when debugging audio applications.
Only the OSS API (not ALSA) is supported. Also, only
pcm (sampled audio) ioctls are decoded, not those
controlling the mixer, MIDI or anything else. This can
easily be added.

The patch has been tested on Linux only. I have taken
the liberty to update the linux/ioctlent.h file by hand
as well, though it is auto-generated. The right
solution would be to add the missing stuff in a
separate file by hand, or to maintain it by hand (it
cannot change much anyway for ABI reasons).
