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

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.

Move idmap to frameworks/base [2/2]

idmap depends on libandroidfw, so it should go in frameworks/base.
This follows AOSP which moved idmap to frameworks/base back in
February of 2014.

tether: tethering chooses wrong upstream when mobile_dun is required

When mobile_dun is required, the default mobile type will
be deleted from upstream list, this makes wifi become
the highest priority upstream even whne wifi is not available.

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.
