bisect: simplify the addition of new bisect terms

Browse Source 
We create a file BISECT_TERMS in the repository .git to be read during a
bisection. There's no user-interface yet, but "git bisect" works if terms
other than old/new or bad/good are set in .git/BISECT_TERMS. The
fonctions to be changed if we add new terms are quite few.

In git-bisect.sh:
	check_and_set_terms
	bisect_voc
