This isn't a great situation -- it suggests the PolicyService
is having some sort of RemoteException -- but when it happens
we should just treat it the same as if the policy is not
enforced.

The IMAP time based query only takes a date, not a
date/time. This means that if we want to load all
messages since, for example, Aug 11 at 3:00 PM,
we'll actually get all messages since Aug 11 at any time.
Our local query actually took into account the time, so
when we loaded a map of local messages, it would not
always include all of the same messages that the IMAP
query would. This meant that if we processed a message
that was in our IMAP query window but not our local query
window, we'd always think it was a new message even
if it wasn't.
It's easy enough to increase the size of our local query
window so that it will definitely include all of the
messages the IMAP query might return, but this adds
a new problem: It's no longer safe to delete any local
message that did not come back in our IMAP query result.
Since our local query may include a larger time window
than the IMAP query window, we need to check each message's
timestamp, and only delete it if it is inside the remote
query time window.

Deleting .db files can make malformed database issues
when WAL(write ahead logging) mode is enabled.
EmailProvider doesn't use WAL mode currently,
But it has to be fixed because it might cause the problem in the
future.

Use DatabaseUtils.longForQuery() method instead of SQLiteDatabase.query().
This reduces processing cost of database cursor.

Now, every 15 minutes we'll sync the last 24 hours.
Every 4 hours we'll perform a full sync, which will
take either the last 7 days, or until the oldest message
we already have locally.

uifolders and uiallfolders cursors now setNotificationUri on
the appropriate uri. That uri is notified whenever:
- A folder is inserted, deleted, or modified.
- A message is inserted or modified (since this can affect
message counts).
This second one is still not quite right: there are some
conditions where counts aren't updating correctly.
While I was here, I renamed the notification uris to
avoid collisions between different versions of the app.

The first problem was that the imap BEFORE clause
is exclusive, so messages on the date given in
BEFORE will not be sent. Now, on the sync for the
most recent messages, we will just not specify a
BEFORE clause, so we can always get the most recent
messages even if our clock drifts from the server.
The second is that some imap servers do not accept
time information on the query dates, and that causes
errors. The imap spec defines the BEFORE and SINCE
clauses to come with a <date> only, not a time,
and although it seems that at least some imap servers
handle that, it can't be expected to always work.
