Refactor ProtectionSystemSpecificInfo class to struct 

This is in preparation of supporting entitlement license API, where
common encryption server may return concatenated PSSHs directly.

Refactored ProtectionSystemSpecificInfo into a struct containing
concatenated PSSHs. This will make it easier to pass PSSHs around.

Also, most of the time, users of ProtectionSystemSpecificInfo do
not care what is in PSSH; so moved PSSH box parsing and building out
of ProtectionSystemSpecificInfo.
