These functions switch computation function suitable for the given HMM types (tied-mixture or shared-state, use GMS or not, and so on). It also sets various parameters and global pointers for the likelihood computation. These functions should be called at first.

How to usage these acoustic computation routines:

1. First call outprob_init() on startup to configure and setup functions
2. For each input,
   1. call outprob_prepare() to prepare cache
   2. use outprob(t, hmmstate, param) to get output probability of a state
