This fixes a race condition that would end up with the spell
checker not finding some words in the user dictionary when it
just booted.

Picking a suggestion inserts a space after the word. This change makes
this space a magic space.

Incidentally, do some minor cleanup: add CODE_DASH, CODE_SINGLE_QUOTE
and CODE_DOUBLE_QUOTE to Keyboard and use them throughout the code,
and remove a useless import directive in some unrelated file.

- Have user-history based bigrams used as soon as they are entered,
  not after 6 times.
- Limit bigram frequency to 255 (this limits the multiplier to 1.8, and
  has no effect on main dict bigrams which already have this limit)
- Some TODO resolving

This change also corrects usage of "frequency", "priority" and "score"
* Frequency is the relative probability in dictionary.
* Score is the relative probability in suggestions.
* Priority is kind a sorted score.

Words that matched user input with skipped characters used to be demoted
in BinaryDictionary by a constant factor and not at all in those dictionaries
implemented in java code. To represent the fact that the impact of a skipped
character gets larger as the word is shorter, this change will implement a
demotion that gets larger as the typed word is shorter. The demotion rate
is (n - 2) / (n - 1) where n is the length of the typed word for n >= 2.
It implements it for both BinaryDictionary and java dictionaries.

This is to avoid ANRs during bootup, as some of the providers
may not have been initialized yet.

Move java code to a different directory so that the unbundled
version doesn't try to compile the native code again.

dictionary.

Example, "ho9" would match "Shoemaker", if "Shoemaker" existed in your
contacts. This was due to premature switch to completions mode when
trying to insert a missing letter.

This syncs up the Java version to what the native one was doing.

This increases the chance of hitting the correct letter when typing a word
that exists in the dictionary, rather than only correct it after the fact.
It is most effective after 2 or 3 letters of a word have been typed and gets
more accurate with more typed letters in the word.

If 2 adjacent letters have similar probabilities of occuring, then there is no
hit correction applied.

When there is more than one instance of a name in the Contacts, it
gets a very high weightage and can override corrections for very
high frequency words such as "the".

This fix prevents multiple occurences from increasing the frequency
of a contact and also from bumping it above 255, which is the frequency
of "the", "is", etc.

First pass at automatically adding new words that the user types and deliberately
accepts.
After typing the word 4 times, the word gets promoted to being valid.
After typing the word 7 times, the word gets added into the UserDictionary and can
be removed from the UserDictionary Settings UI.

Also add a second row of symbols to the period popup.
