Initial code for TGBA (Transition Generalized Bchi Automata).

Browse source 
Contains tgba_bdd, a BDD-encoded TGBA, and ltl_to_tgba,
a LTL-to-TGBA translator using Couvreur's algorithm.

* src/Makefile.am (SUBDIRS): Add tgba.
(libspot_la_LIBADD): Add tgba/libtgba.la.

// - atomic propositions, which are things to verify before going on
// to the next state
// - promises: a U b, or F b, both implie that b should be verified
// eventually. We encode this with Prom[b], and check
// that promises are fullfilled in the emptyness check.
