7dca3ab1ea Make local functions really local 
Rename the local functions to snd1_* so that they won't be exported
out of alsa-lib.

Some functions are still kept because aserver requires them.  Sigh.

d5caee8d36 Fix bogus value when no user TLV is defined 
Check whether non-zero size TLV is really returned by comparing
with the pre-filled pattern.  ALSA 1.0.12 driver doesn't notify
the error even if user TLV is empty, so the previous value is
passed bogusly.

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.
