2a7f35347b Make snd_hctl_wait() respect the API 
snd_hctl_wait() currently makes a lot of assumptions that fall outside
the defined API. snd_pcm_wait(), however, follows the API nicely so the
new version is based on that.

09f598e57c allow changing of device directory path 
Add configuration options to change the default device path from the
default /dev/snd.  This is useful for embedded systems that do not want
subdirectories in /dev.
