added snd_hctl_ctl() function

Browse source 
ordinary mixer:
  - revised Ordinary Mixer I/O type
  - sndo_mixer_open() take PCMs rather than strings to pass
    the real relationship
  - an initial version of toplevel alisp script
more alisp development:
  - renamed a* functions to A* functions (acall -> Acall etc.)
  - many improvements (unset*, exfun, Acall pcm_info, Asnderr, Asyserr)
