Add analysis support for ContentProviders

Inter-component communication analysis should support ContentProviders as well.

I'm currently having problems to resolve name expressions. Consider the following case

int a = 10;
compute(a);

On the example, I am able to find method call "compute" and its parameter "a". The problem is finding the actual value of "a".

What I am trying to do is to search method calls for "query" and get the actual value of the content URI, usually declared on the same method:

public static final String AUTHORITY = "org.thialfihar.android.apg.provider";

// (...other constants...)

public static final Uri CONTENT_URI_PUBLIC_KEY_RING_BY_EMAILS = Uri.parse("content://" + AUTHORITY + "/key_rings/public/emails/");

// (...in a given method...)
Uri contentUri = Uri.withAppendedPath(Apg.CONTENT_URI_PUBLIC_KEY_RING_BY_EMAILS, emails);
Cursor c = activity.getContentResolver().query(contentUri,
                       new String[] { "master_key_id" }, null, null, null);
