Merge "app install on sdcard. provide skeleton implementation to install an app on sdcard, just resources. Add new install path for /asec in installd. ignore . when checking for apk path since the sdcard packages id'ed by package name. Add new -s option to adb shell pm Refactor fwd locked from scanMode to ApplicationInfo. Add new flag for sd install Add new parse flags for fwd locking and installing on sdcard New mock api's in PackageManagerService to invoke MountService api's. These will be refactored again and so have been wrapped internally. Some error codes in PackageManager Changes in PackageManagerService to use mPath and mScanPath during installation and switch to using PackageParser.Package.applicationInfo attributes for source and public resource directories. Some known issues that will be addressed later  using system_uid for now. needs some tinkering with uid and packagesetting creation to use the actual app uid  error handling from vold not very robust. ignoring lot of things for now  sending a delayed destroy to delete packages. will revisit later  revisit temp file creation later. just copy for now"
