audio(7I) suggests that applications do the following to get the
device and control pseudo-device:
- first look for the device filename in the environment variable
AUDIODEV.
- if not found, use /dev/audio
- calculate the control device by tacking "ctl" onto the base device
name.
We now do this. Also, if the open fails, we call
PyErr_SetFromErrnoWithFilename() to give a more informative error
message.
Added a fileno() method to the audio object returned from open().
This returns the file descriptor which can be used by applications to
set up SIGPOLL notification, as per the manpage.
