r708: implemented double Z-drop thresholds ( #112 )
...
When aligning long reads, we would prefer to align through low-quality
regions. This requires a large Z-drop threshold. However, to find small
inversions, we need to use a small Z-drop. This commit address this
conflict with two Z-drop thresholds. When Z-drop exceeds the smaller
threshold, we perform a local alignment to check if there is a potential
inversion. If there is one, we break the alignment; otherwise we break
the alignment only if Z-drop excess the larger threshold.
This commit also fixes a bug that reported wrong coordinates when the
inversion is on the forward strand (#112 ).

r557: fixed another mapq underestimate
...
When a chain is split during base-level alignment, its chaining score is
reduced. However, the chaining score of its suboptimal chain remains the same.
This leads to underestimated mapping quality.
