This creates a new DictionaryInfoUtils class and moves a bunch
of static methods there for later usage.

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.

Also, optimize quite a bit the code that decides whether we have
a default dict or not.

Checking the magic number of a file upon decoding is necessary,
because if the file is corrupt and we don't check it, we will
fall back to a simple copy of the corrupted file. Latin IME
would realize this and would not crash, but would not use the
corrupted dictionary. If this happened to be a main dictionary,
then the user would lose the ability to use the correct
built-in dictionary.

Not the same, but kinda similar to

The message this removes gets printed under normal conditions.
Normally dictionary files are compressed then crypted, but not
compressed a second time; however LatinIME tries to open a
compressed-crypted-compressed file first, because it could not
do it afterwards and we want to support this case. So under
normal operations, the first method LatinIME tries is actually
expected to fail.
Also, if we decide to stop compressing or/and encrypting dicts
LatinIME supports it as a valid use case. It should not print
errors to the log.

If the file cannot be open at all, then it is an unexpected
case, and Latin IME still reports to the log.

Now that the dictionary pack can return several files, it's better
to handle IO exceptions for each file rather than globally. This
also will help with next implementation steps.

The dictionary filename used to be passed directly to Latin IME.
This change implements, on the part of Latin IME, the passing of
them as an id that should then be passed through
openAssetFileDescriptor.

This is necessary because we don't know any more whether the
locale of the process is the expected one when the dictionary
is loaded asynchronously.

This change enables the interface to get multiple dictionaries from a
dictionary pack. It only implements it to the end in the case of the
proprietary method, as the open method needs still some working out,
and the "inside the package" method does not need it.

This change goes together with Iaa95bf36, and breaks the build
without it.

This update is necessary to allow dictionary content providers to use
assets, which are part of their apk, as data to pass to the keyboard.
Using plain file descriptors doesn't allow for sections of files to
be correctly used.
