49ba135fde Perform the actual bigram frequency lookup.
This still returns the unigram frequency, because the values stored
for bigrams in the dictionary are not ready to be returned in-place
instead of unigram values. Aside from this, the code is complete.

8950ce6c44 Replace the bigram list position with the map and filter
Passing the position will not allow us a reasonable lookup
time. Replace this with a map and bloom filter for very fast
lookup.

1ff8dc47be Fill up a map of bigram addresses for lookup.
We don't want to do a linear search on each terminal when there
may be 100+ bigrams for a given word because that would be
disastrous for performance. Also, we need to resolve each bigram
address anyway.
This change resolves the addresses at first and puts them in a
balanced tree so that lookup will be O(log(n)).

This is a cherry-pick of change I2d81742f

4d9b202c40 Pass the bigram list position from the top level
The position itself is still a const int = 0 until we have the previous
word passed to the function. This basically does the plumbing.

171d1809ff Add methods to inverse compute the probability.
For now the probability is just returned with the same
value it had, but this is some ground work that needs to be
done anyway.

522a04ea5b Pass words as int[] to the native code.
We need to get the bigrams during the call to getSuggestions for
bug#6313806. We already give an int[] to getSuggestions and we
wanted to get rid of char[]'s anyway because it doesn't work with
surrogate pairs, so here we go.

ee396df162 Fix a native crash
This was introduced by Ieb2e306a which failed to keep the return
behavior in case the word doesn't have a bigram.

function. This is a preparative change to bug#6313806

This leak was about 500k and would happen whenever a new binary
dictionary was opened/closed.
