The ltl_to_tgba_fm() translation function was using a hash_map of
maps (ugh!) to merge transitions on output.  However recent libstd++
changed the implementation of hash_map (a.k.a. unordered_map) causing
transitions to be output in a different order.  This
implementation-dependent order caused the ltl2ta.test to fail because
the BA->TA transformation can produce TA of different sizes if you
simply change the order of transitions in the input BA! This does not
sound like a nice property for the BA->TA transformation, but Ala Eddine
isn't sure how to fix it yet.  In the meantime, this patch makes sure
ltl_to_tgba_fm() will return the same output regardless of the
implementation of hash_map.

The ltl2ta.test failure has been observed with g++ 4.9.2 on Arch Linux,
and with gcc-snapshot (5.0.0 20141016) on Debian.

* src/tgbaalgos/ltl2tgba_fm.cc: Rewrite the transition merging
using a std::vector and std::sort instead of nested maps tables.
* src/tgbatest/ltl2ta.test: Adjust sizes to the new order.
* NEWS: Mention the fix.

This is a huge patch, that took over a month to complete.  The bit sets
are currently restricted to what 'unsigned can store', but it should be
easy to extend it to 'uint64_t' should we need it.

* NEWS: Update.
* src/tgba/acc.hh: New file.
* src/tgbatest/acc.cc, src/tgbatest/acc.test: Test it.
* src/tgba/tgbakvcomplement.cc, src/tgba/tgbakvcomplement.hh,
src/tgba/tgbasgba.cc, src/tgba/tgbasgba.hh: Delete.  The KV
complementation is too slow to be used in practice, and I somehow broke
it during the conversion to bitsets.  The tgba->sgba conversion was only
used for the KV complementation, and should be better redone on
tgba_digraph_ptr should it be needed again.
