Add snd_{ctl|pcm}_open_fallback() functions
This patch adds new API functions, snd_ctl_open_fallback() and
snd_pcm_open_fallback(). These are just like snd_*_open_lconf() but
used to open a fallback PCM/control. The difference is that it replaces
the name string with the given original name, so that hctl and other
upper-layers will recognize it as an alias.
