Last step of the algorithm in virDomainSnapshotAlignDisks is to extend the array of disks to all VM's disk and provide defaults. This was done by extending the array, adding defaults at the end and then sorting it. This requires the 'idx' variable and also a separate sorting function. If we store the pointer to existing snapshot disk definitions in a hash table and create a new array of snapshot disk definitions, we can fill the new array directly by either copying the definition from the old array or adding the default. This avoids the sorting step and thus even the need to store the index of the domain disk altogether.
