/* Function: p7_Calibrate()
* Synopsis: Calibrate the E-value parameters of a model.
* Incept: SRE, Thu Dec 25 09:29:31 2008 [Magallon]
*
* Purpose: Calibrate the E-value parameters of a model with
* one calculation ($\lambda$) and two brief simulations
* (Viterbi $\mu$, Forward $\tau$).
*
* Args: hmm - HMM to be calibrated
* cfg_b - OPTCFG: ptr to optional build configuration;
* if <NULL>, use default parameters.
* byp_rng - BYPASS optimization: pass ptr to <ESL_RANDOMNESS> generator
* if already known;
* <*byp_rng> == NULL> if <rng> return is desired;
* pass <NULL> to use and discard internal default.
* byp_bg - BYPASS optimization: pass ptr to <P7_BG> if already known;
* <*byp_bg == NULL> if <bg> return is desired;
* pass <NULL> to use and discard internal default.
* byp_gm - BYPASS optimization: pass ptr to <gm> profile if already known;
* pass <*byp_gm == NULL> if <gm> return desired;
* pass <NULL> to use and discard internal default.
* byp_om - BYPASS optimization: pass ptr to <om> profile if already known;
* pass <*byp_om == NULL> if <om> return desired;
* pass <NULL> to use and discard internal default.
*
* Returns: <eslOK> on success.
*
* Throws: <eslEMEM> on allocation failure.
* <eslEINVAL> if <hmm>, <gm>, <om> aren't compatible somehow.
*
* Xref: J4/41
