bug:3360821
1. While my previous change:I3baff68c has partially fixed this bug
it was still possible for a callback to be invoked on init. If a
callback was already regitsered and the init is called the
callback is incorrectly notified.

ContentProviders are allowed to return null and both
of our contact directories (Focus and Exchange) actually
do when they find no data to return.
The problem is that when LoaderManager receives a result
from a loader, it checks if the result is the same as
previously received. That's fine, as long as the loader
always returns a different result. Now consider a loader
that returns null when it cannot produce the result.
What we are seeing is that if the loader is rapidly restared
and returns null twice in a row, the null is never
delivered to the callbacks.
In the case of the reported bug, the scenario is this:
1. We look for "foo"
2. Data for "foo" comes from a directory and we display it
3. We hit backspace twice in rapid succession. Each time
we hit backspace, the loader is restared, but since we do
this very fast, the second restart overrides the first. So
far so good.
4. The directories are programmed to return null if the
query string is less than 3 characters long, so the loader
returns null twice.
5. Loader manager looks at the final result, compares it
to the previous result and since they are the same (both null)
concludes that it does not need to deliver either of them.
6. The UI attempts to show the stale data and blows up

This enables the system bar to carve out a region through which
events will be sent to the IME behind it.

Also hide the bitmap thumbnail stuff, we can't support it in its
current form.
And fix some bugs with propagating paths to native code. Yikes!

action items are added
Rules for action bar overflow:
Items are considered for inclusion in the order specified within the
menu. There is a limit of a total count, optionally including the
overflow menu button itself. This is a soft limit; if an item shares a
group ID with an item previously included as an action item, the new
item will stay with its group and become an action item itself even if
it breaks the max item count limit. This is done to limit the
conceptual complexity of the items presented within an action
bar. Only a few unrelated concepts should be presented to the user in
this space, and groups are treated as a single concept.
There is also a hard limit of consumed measurable space. This limit
may be broken by a single item that exceeds the remaining space, but
no further items may be added. If an item that is part of a group
cannot fit within the remaining measured width, the entire group will
be demoted to overflow. This is done to ensure room for navigation and
other affordances in the action bar as well as reduce general UI
clutter.
The space freed by demoting a full group cannot be consumed by future
menu items. Once items begin to overflow, all future items become
overflow items as well. This is to avoid inadvertent reordering that
may break the app's intended design.

Bug: 3184831
Copied holo layouts to *_holo.xml and restored the old layouts for
non-holo (pre-honeycomb) apps to use so that their layout assumptions
aren't messed up.
