clear the DFA without depending on Hopcroft minimisation.

dump: always allocate >=8 bytes for multibit
...
The multibit runtime assumes that it is always safe to read 8 bytes, so
we must over-allocate for smaller sizes. Caught by ASan.

- Use a queue rather than always building the full vector of state
sets.

flat_set/map: workaround for gcc-4.8 C++11 defect
...
The STL shipped with gcc-4.8 does not provide
vector::erase(const_iterator) for C++11, instead only taking a mutable
iterator. This causes problems with flat_set/map if we don't have
Boost small_vector available and we fall back to std::vector.
We work around this by providing a function to construct a mutable
iterator given a const_iterator for internal use.

gcc7: comments for falling through a switch case

GCC 7 adds a warning -Wimplicit-fallthrough to catch when falling
through a switch statement without a break. Since we actually want that
behaviour sometimes, we can add a comment so the compiler knows we
intended the fallthrough.
