/**
 * Modifies the entries in the resource table to account for compatibility

 * This primarily handles the issue of private/public attribute clashes

 * and then followed those public definitions with private attributes.
 *
 * --- PUBLIC ---
 * | 0x01010234 | attr/color
 * | 0x01010235 | attr/background
 *
 * --- PRIVATE ---
 * | 0x01010236 | attr/secret
 * | 0x01010237 | attr/shhh
 *
 * Each release, when attributes are added, they take the place of the private
 * attributes and the private attributes are shifted down again.
 *
 * --- PUBLIC ---
 * | 0x01010234 | attr/color
 * | 0x01010235 | attr/background

 *
 * Platform code may look for private attributes set in a theme. If an app
 * compiled against a newer version of the platform uses a new public
 * attribute that happens to have the same ID as the private attribute
 * the older platform is expecting, then the behavior is undefined.
 *
 * We get around this by detecting any newly defined attributes (in L),
 * copy the resource into a -v21 qualified resource, and delete the
 * attribute from the original resource. This ensures that older platforms
 * don't see the new attribute, but when running on L+ platforms, the
 * attribute will be respected.
