This implements the skeleton implementation, and enables a
fallback implementation in the case the file is coming from the
dictionary provider.
- A better scheme should be used for provider-supplied dicts.
- This does not implement the solution for device-generated
    dicts yet. This will come in a future change.
- This does not implement the checking process on the native
    side yet. This will come in a future change.

Emit a trace when a new dictionary is copied to LatinIME
successfully, not just when it fails. That will help diagnosing
some problems by being able to ensure this step succeeded
looking at the log.
This does not happen often (like, maybe 3 times at device
activation, and once every few weeks afterwards), so I think
the extra line in the log is more than acceptable.

There is no reason not to contact the dictionary provider
when we don't have internet permission or when the URL
is empty. It knows how to handle both these cases.

Upon invoking the settings of the dictionary pack with an unknown
client, we now launch an intent to ask the client to make itself known.
This change also includes the code that receives this intent and
acts upon it.

Improve a slew of logging statements, and put commands that we don't
expect to need protecting against exceptions out of a try {} block.

In this kind of series of calls, it's possible that an outer call to a
constructor fails, but the inner succeeded.
Example:
try {
    is = new A(new B());
} finally {
    if (null != is) is.close();
}
In this case, if new B() succeeds but new A() throws an
exception, is stays null and the intermediate object is never
closed. This is what was happening in this instance.

This introduces a new textual format for the dictionary that combines
words, bigrams and shortcuts to avoid complexity. It is also extensible
to n-grams to fool-prof for the future, and easier to read than XML.

When a dictionary changes locale, we need to remove the file
that corresponds to the old version. It has a different path
than the new one, so we have to search for it explicitly.
