Add snapshotProfile APIs to installd
Add APIs that will snapshot the profile information of packages
in a well known location.
The snapshot ownership is given to AID_SYSTEM. The location is
next to the application reference profile:
/data/misc/profiles/ref/pkg_name/primary.prof.snapshot.
The intended flow for snapshotting profiles is:
mInstaller.snapshotProfile(appId, packageName, codePath);
// open profile snapshot
mInstaller.destroyProfileSnapshot(packageName, codePath);
The reference profile directory is made searchable by others
(in order for the system to be able to open the snapshot profile).
