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

Before this patch if phone was left on long enough it would reboot
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.
