simulation: Fix co-simulation and iterated simulations of BA automata

Browse source 
* src/tgbaalgos/simulation.hh, src/tgbaalgos/simulation.cc
(simulation_sba, cosimulation_sba, iterated_simulations_sba): New
function.  Also speedup the existing functions by avoiding
add_acceptince_conditions() and add_conditions().  Finally, use
scc_filter_states() when dealing with degeneralized automata.
* src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh (do_ba_simul):
New method.  Use it after degeneralization.
* src/tgba/tgbaexplicit.hh (get_transition, get_state): New methods.
* src/tgbatest/basimul.test: New file.
* src/tgbatest/Makefile.am (TESTS): Add it.
* NEWS: Introduce the new function and summarize the bug.
