* - accscore is the accuracy found by the fast (vector) code DP implementation.
* - accscore_g is the accuracy found by the generic DP implementation.
* accscore and accscore_g should be nearly identical,
* within tolerance of roundoff error accumulation and
* the imprecision of Logsum() tables.
* - accscore_g2 is the accuracy of the traceback identified by the generic
* DP implementation. It should be identical (within order-of-evaluation
* roundoff error) to accscore_g.
*
* the "accscore_g2 < accscore_o" test is carefully contrived.
* accscore_o is a theoretical lower bound but because of fp error,
* accscore and (much more rarely) even accscore_g can exceed accscore_o.
* accscore_g2, however, is calculated with identical order of evaluation
* as accscore_o if the optimal trace does turn out to be identical to
* the originally emitted trace. It should be extremely unlikely (though
* not impossible) for accscore_o to exceed accscore_g2. (The DP algorithm
* would have to identify a trace that was different than the original trace,
* which the DP algorithm, by order-of-evaluation, assigned higher accuracy,
* but order-of-evaluation in traceback dependent code assigned lower accuracy.

/* Function: p7_domaindef_GlocalByPosteriorHeuristics()
* Synopsis: Define glocal domains in a sequence using posterior probs.
* Incept: EPN, Tue Oct 5 10:02:34 2010
* SRE, Sat Feb 23 08:17:44 2008 [Janelia] (p7_domaindef_ByPosteriorHeuristics())
*
* Purpose: Given a sequence <sq> and model <gm> for which we have
* already calculated a Forward and Backward parsing
* matrices <gxf> and <gxb>; use posterior probability
* heuristics to determine an annotated domain structure;
* and for each domain found, score it (with null2
* calculations) and obtain an optimal accuracy alignment,
* using <fwd> and <bck> matrices as workspace for the
* necessary full-matrix DP calculations. Caller provides a
* new or reused <ddef> object to hold these results.
*
* As a special case, if the profile is in unihit mode
* upon entering, we don't ever modify its configuration.
* This is especially important if this function is
* being used within a search/scan pipeline with a
* specially configured p7 profile in which N->N and/or
* C->C transitions have been set to IMPOSSIBLE. (If
* we were to call ReconfigLength() on such a profile
* we would make those transitions possible.)
*
* One case in which profile reconfiguration is necessary
* is when multiple domains are suspected. However, we
* guard against this if the profile enters in unihit mode
* by no allowing multiple domains (in fact, it should
* never happen because J states are unreachable in unihit
* profiles). If multiple domains are suspected in this case,
* we return eslEINCONCEIVABLE.
*
* Upon return, <ddef> contains the definitions of all the
* domains: their bounds, their null-corrected Forward
* scores, and their optimal posterior accuracy alignments.
*
* <do_null2> is TRUE if we'll eventually apply a null2
* penalty FALSE if not. If FALSE, we can save time by
* skipping Backward calls at some stages.
*
* Returns: <eslOK> on success.
*
* <eslERANGE> on numeric overflow in posterior
* decoding. This should not be possible for multihit
* models.
*
* <eslEINCONCEIVABLE> if profile enters as unihit but
* multiple domains are suspected.
