Mms: Clean up delivery report dialog.

Instead of launching another activity just to show the delivery report,
mimic how showMessageDetails works instead, using AlertDialog.Builder.
This ports the dialog over to Holo as well.

Display message type properly for MMS and SMS

When a message is showed details, android will search it in mms
& sms list according to its message id. But sometime the message
id of sms message is the same with that of mms message and the
special mms message is before the sms message in mms & sms list,
so the sms is displayed as mms.

To fix this bug, message type is to be checked at the same time.

Resize the image in background

Decoding and resizing of the image is done in
Adapter-getView method which runs in the main
thread. As a result edit screen resumes after
few seconds, mean time if user flings on that
activity it leads to ANR.

From getView method, adopt lazy loading - spawn
the thread which will decode and resize the
image, upon receiving the requested resized-image
set the image to the view.

MMS: Fix The slideshow can't be shown in the message

After the MessageItem Pdu Loaded, the MessageItem's AttachmentType
might have changed. So precisely, it's not the same MessageItem
anymore.Since it's not the same MessageItem, we should setImage,
and the slideshow will be shown normally.

After Pdu Loaded, when bindCommonMessage again, the sameItem
argument should be false, because it's not the same MessageItem
anymore.
