Themes: Build icon cache when applying icons

The theme service will schedule building of the icon cache when
an icon pack is applied.  This will allow the icon cache to be
populated immediately after icons are applied rather than build
it up as icons are requested.

Themes: Pass resource IDs instead of bitmaps [1/2]

Rather than passing around bitmaps in the ComposedIconInfo we
can pass the resource IDs associated with each of the components
and retrieve those drawables when composing the icon.

Themes: Allow clearing the wallpaper and ls wallpaper

By providing an empty string for the MODS_LAUNCHER and
MODS_LOCKSCREEN components, the theme service will clear out any
existing wallpaper the user had set.  This provides the same
functionality as if the user was picking "No wallpaper" from the
picker.

Make sure ThemeConfig is non-null when loading resources

When the device boots into safemode, the theme config will end up
being null and we need to check that prior to using it to retrieve
resources for the StatusBarIconView

This fixes CYAN-5009

Themes: Add ability to apply color filters to composed icons

Themes can include one or more of the following filter tags in
assets/icons/res/xml/appfilter.xml

    <!-- HUE filter
         Integer value between -180 and 180 representing the degree.
         0 = no change
    -->
    <filter name="hue">0</filter>

    <!-- SATURATION filter.
         0 = grayscale, 100 = no change, 200 = over saturated
    -->
    <filter name="saturation">0</filter>

    <!-- BRIGHTNESS filter.
         0 = pitch black, 100 = no change, 200 = 200% brightness
    -->
    <filter name="brightness">100</filter>

    <!-- CONTRAST filter.
         -100 = minimal contrast, 0 = no change, 100 = maximum contrast
    -->
    <filter name="contrast">100</filter>

    <!-- ALPHA filter.
         0 = transparent, 100 = opaque
    -->
    <filter name="alpha">75</filter>

    <!-- INVERT filter.
         Valid values are true or false
         true = invert colors
    -->
    <filter name="invert">false</filter>

    <!-- TINT filter.
         A hexadecimal value representing ARGB
    -->
    <filter name="tint">#ff0000ff</filter>

Themes: Make sure composed icon info is meaningful

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: 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.
