Minor cleanup on the way to fixing spelling for downloaded language.

Bug 19710676.

Change-Id: I7be25fa82248f0317d894d44802bede9dbc4fe2a

Simplify interfaces by passing Keyboard instead of
KeyboardLayout and ProximityInfo directly.  Also require
the Keyboard passed be non-null and change the SpellChecker
to bail out if there is no keyboard for the locale.

This is apparently called only once for every unique word, so repeated instances
of the same word are not handled separately. Upon changing orientation of the
device, however, all invalid words in the textbox are underlined again and this
method is called for each unique instance in order.

package as much as we can.

This member has outlived its usefulness. It's not clear now that it
makes things really faster, but it does bring a lot of complexity
that we can avoid by removing it.

This is not the right way to do it, but it's simple and will kill the
regression. We should investigate why the return values are
wrong in this case.

getSuggestion() is called from spell checker.

This is about as ad-hoc as it gets, but then again, what we want
is probably as ad-hoc as it gets.
All URL boxes I know of double as search bars, and not adding
automatic spaces there sucks (e.g. in Chrome URL bar).
And in other boxes actually you don't want to add a space if
it looks like a URL. QSB isn't even a search box, and it behaves
like this.

So I think this is actually the right answer to the problem.
