Fix: wallpaper changes when changing lockscreen WP

Since LockscreenWallpaperPickerActivity did not override
cropImageAndSetWallpaper the homescreen wallpaper was changing
when selecting the default_wallpaper resource.

Themes: Make sure composed icon info is meaningful

We don't want to try and create a composed icon if the parts that
make up a composed icon are not valid or set.

Themes: Fix blurry composed icons

In a composed icon the original icon could be scaled incorrectly
due to a density mismatch resulting in blurry icons.

For example, Grouper has a screen density of 213 dpi but Trebuchet will want to show a larger icon and therefore
requests to the framework to load app icons with a slightly higher density of 320dpi (XHDPI bucket).

When Resources.loadDrawable(TypedValue value, ...) is called, it will use observe value.density. Since the image
is from the XHDPI bucket it will have a TypedValue.density of 320dpi, much higher than the screen's 213dpi, and therefore
loadDrawablei() will configure BitmapFactory to scale down the image to match the screen density. This is not what we want,
so this patch modifies the density value to prevent scaling, much the same way getDrawableForDensity() does.

Themes: Load missing style attributes from original style

If a theme overrides a style in an app and does not include all
the attributes found in the original, it is possible for the app
to crash because it cannot locate an attribute it is expecting.

To overcome this we need to check the attributes in the original
style's bag and add any missing attributes to the current bag being
populated.  Currently we have only seen one theme that causes this
behavior, but there could be others out there or we may eventually
see this happen in the wild as apps update and the themes have not
had a chance to incorporate the new additions from the app.

Themes: Avoid NPE when setting text in TickerView

It is possible, with the right timing, to receive an NPE in TextSwitcher
when a notification comes in during recreation of the status bar because
of a theme change.

Themes: Track NotFoundException on app launch failure

We should probably keep an eye on NotFoundExceptions too since they
are a common exception thrown when a bad theme is applied.

Themes: Remove listener if exception is thrown

If something goes wrong and a client does not remove itself, the
theme manager may still have a reference to the listener and an
exception is thrown while trying to call one of the listener's methods.
When this happens, we should not only log it but remove the bad listener.

Themes: Fix native crash in libandroidfw

If a missing attribute needs to be added in somewhere in the middle
of the bag, a segfault would occur because we change curEntry to a
value that is beyond the set's allocated space.  This patch stores
curEntry in prevEntry before changing it's value and memmove uses
prevEntry to index the set.
