Change storage migration to use quota APIs.
New quota APIs are much faster than trying to measure manually, and
removing this last user of calculateDirectorySize() means we can
remove it once and for all.

Offer to wait until broadcasts have drained.
We've seen evidence of lab devices racing with other apps that are
using cache space immediately after tests wipe it clean, which can
cause test failures. To mitigate this, try our best to wait for the
device to go "idle" by watching for broadcast queues to fully drain.
Also improve javadocs along the way.

Respond to API council feedback.
Move aggressive allocation to @SystemApi, which means we can hide
the "flags" API variants.
Remove UUID APIs, since we should use existing Serializable APIs.
Relax permission checks to allow apps to ask for their own stats.
Improve docs.

Fix code accounting bugs, track external app data.
When counting code size, don't include APKs baked into the system.
Settings already accounts external storage used by apps, so they
need a way to exclude that from the total space used by external
storage; give them new getAppSize() API.
Refine docs to explain that emulated storage might be included in
measured statistics.
Resolve symlinks as part of matching getUuidForPath().

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.
