Wire up storage stats API to installd.
Now that installd has the implementation details we need, we can wire
up the public APIs to use them.
Shuffle APIs around a bit so that StorageStats can be reused for both
UID and UserHandle results, and rename StorageSummary to
ExternalStorageStats. Provide getTotalBytes() and getFreeBytes() as
first-class methods so we can answer those questions quickly without
paying the cost of measuring external storage details.
Current costs on a typical device with a test account after flushing
dentry caches:
queryStatsForUid() manual: 6922ms
queryStatsForUid() quota: 525ms
queryStatsForUser() manual: 1686ms
queryStatsForUser() quota: 113ms
queryExternalStatsForUser() manual: 42ms
queryExternalStatsForUser() quota: 2ms
For verification purposes, a new "fw.verify_storage" system property
can be set to compute both manual and quota statistics, and log any
discrepancies.
Test: builds, boots
