NetworkStats.Bucket API polish.
-Add @IntDef constants for STATE_ and ROAMING_.
-Expand docs for ROAMING_ constants.
-Use ROAMING_NO/YES instead of ROAMING_DEFAULT/ROAMING.

Implementation of data usage callbacks.
NetworkStatsService will register data usage requests
and keep data usage stats scoped to the request.
There are different types of data usage requests
- scoped to a set of NetworkTemplate; these are restrictred to
device owners and carrier apps and allow the caller to monitor
all activity on the specified interfaces.
- scoped to all uids visible to the user, if the user has
android.Manifest.permission#PACKAGE_USAGE_STATS permission.
The set of uids may change over time, so we keep track of that.
- scoped to a set of uids given by the caller, granted that
the caller has access to those uids.
- scoped to the caller's own data usage. This doesn't require
PACKAGE_USAGE_STATS.

Implement roaming tracking in NetworkStats summary queries.
Whether a network is deemed roaming or not was already being tracked
as part of the NetworkIdentitySet, so the underlying data store
already tracks roaming and native data separately. However, this data
was being aggregated together in NetworkStatsCollection#getSummary,
since the NetworkIdentitySet is converted to an iface name for the
purposes of matching, and the iface name will be identical whether or
not the iface is considered roaming. Now it is separated.
Also fixes a long-standing bug in NetworkIdentitySet where an identity
read from a saved file would always be considered roaming == false,
even if it wasn't at the time it was written.

Relax permissions around NetworkStatsManager APIs.
Currently, access to network usage history and statistics requires a
signature|privileged permission, an AppOps bit (associated with the
PACKAGE_USAGE_STATS permission), or device/profile ownership. Once
access is granted via one of these mechanisms, it generally applies to
any UID running in the same user as the caller.
This CL expands access as follows:
-Any app can access its own usage history with no extra requirements.
-Carrier-privileged applications can access usage history for the
entire device.
-Device owners can access per-UID breakdowns for usage. Previously
they could access the summary for the whole device, but not the
individual breakdowns.
We simplify the permission model by defining three access levels -
DEFAULT (own app only), USER (all apps in the same user), and DEVICE
(all apps on the device), and propagate these levels throughout.
Finally, this CL fixes an apparent bug in
NetworkStatsSerice#hasAppOpsPermissions - if the AppOp bit was in
MODE_DEFAULT, hasAppOpsPermission would always return false instead of
falling back to the PackageManager permission check.

Data usage API: any uid is accessible to system apps running in any user
This CL mostly affects Settings app as it can run in a user different
than UserHandle.OWNER. Since it is a system app it should have access
to all uid's data usage, regardless of which user it is currently running
in.

Keep debug information in NetworkStats files
Create two special SETs.
SET_DBG_VPN_IN is used by individual applications to know
how much traffic of the NetworkIdentity was actually moved
from a VPN app.
SET_DBG_VPN_OUT is used by the VPN app to know how much
traffic of the NetworkIdentity was deducted.
A debug application can restore the raw stats by these
entries.
raw_traffic = recorded_entry (TAG_NONE, SET_ALL)
+ recorded_entry (TAG_NONE, SET_DBF_VPN_OUT)
- recorded_entry (TAG_NONE, SET_DBF_VPN_IN)
The two debug SETs are not returned by
NetworkStatsService.openSession(). These debug entries are
retrieved by NetworkStatsCollection.dump().

Data Usage public API
Added new API consisting of android.app.usage.NetworkUsageManager and
android.app.usage.NetworkUsageStats. Through them data usage on a
network interface can be programmatically queried. Both summary and
details are available.

Lightweight checkin output for network stats.
Define and print a compact version of network statistics when dump
is requested with the "--checkin" flag. Defaults to last 24 hours,
but included data can be tweaked with various flags.
Groups together detailed network identities into larger umbrella
terms like "mobile" and "wifi."

Move some system services to separate directories
Refactored the directory structure so that services can be optionally
excluded. This is step 1. Will be followed by another change that makes
it possible to remove services from the build.
