CM11 Themes: Take into account ALL res/xml dirs

Only res/xml was being searched for redirection XML files, which
causes themes that use xml-v14, xml-v19, etc to be overlooked and
resources not being mapped.

CM11 Themes: Use 32bit hash to decide if idmap should be created

Using the last modified time of the package to determine if an idmap
should be created is not always valid for system packages.  We have
observed some packages having a time stamp of 08/01/2008 even if the
package has changed.  This causes system packages, such as
frameworks-res.apk to not be properly mapped if IDs changed in this
package.

This patch will generate a 32 bit hash code based on the file's
MD5 sum.  This hash code is then provided to idmap for writing these
values into the idmap header for future comparison.

This patch requires the following change found in frameworks/native

Cleanup theme assets when done with them

when a theme was applied due to files being left open.

Return system theme when SecurityException is caught.

Isolated processes cannot access content resolvers so a SecurityException
will be thrown when calling getBootTheme.  This catches that
exception and returns sSystemTheme.

CM11 Themes: Common overlay for sharing resources. [1/2]

This patch will allow themes to contain common resources
which can be shared by all overlays.

Common resources will reside in assets/overlays/common and
can be referenced by other overlays.

Common resources will be referenced using the common package
name, i.e. To reference the common drawable some_drawable for
com.example.theme the theme designer would use
"@*common:drawable/some_drawable"

CM11 Themes: Ensure customTheme is not null.

The configuration retrieved via getConfiguration() sometimes contains
a null customTheme which results in the theme returning to holo when
applying a component such as icons.  Icons will change but styles
and fonts would return to the default.

CM11 Themes: Properly handle themeing apps on install

Previously when an app was installed or re-installed it would not
pick up the currently applied theme.

mOverlays was not being properly updated and therefore newly
installed or re-installed apps would not pick up the currently
applied theme.

CM11 Themes: Fix how common resources are found

During the boot process, application info may not be fully
available and createPackageContext can throw a null pointer which
causes a theme's resource-cache to be cleared.  If this theme is
in /system/app or /system/priv-app the theme will still be installed
but applying it will result in styles not being applied.

Themes: Support launcher based icon packs [1/2]

Before this patch, icon packs written for Trebuchet/Nova/Apex could not be used
with the new theme engine as the formats were different. Particularly the icon package IDs are 7F,
the same ID as as regular apps. Furthermore the location of resources in these icon packs was different
from what the theme engine expects. This patch adds support for these icon packs by overriding
the pkg id.

AssetManager now can override package ids without requiring aapt to recompile the APK.
Note: XML references will still use the original id compiled with AAPT, so it is only useful for resources
which do not use xml drawables (such as icon packs).

PackageInfo now has a new member identify "legacy" (3rd party icon packs) written
for launcher's like Trebuchet, Nova, and Apex.
