Make sure the number of entries written by Parcel#writeMapInternal
matches the size written. If a mismatch were allowed, an exploitable
scenario could occur where the data read from the Parcel would not
match the data written.

Added note within getSerial() in android.os.Build class. Device
identifiers, such as hardware serial numbers, can be modified if a
device is rooted. Others can use key attestation to discover these
changes. Added a note to this effect within this method.

Instead of using the whole slab mem for kernel usage, split the
unreclaimable to kernel and reclaimable to cache (since is freed
under mem. pressure).

Cleanup of Cellular/Wifi aggregate statistics in Batterystats dumpsys
Cellular
- Modification of field names to improve clarity
- Removed count "x" values
- Added power values to Rx signal strength
- Added power values to Tx power
- Added "Cellular Sleep time"
- Removed erroneous battery field (This is being fixed in b/67213886,
b/67213967)
- Removed the following fields (Mobile radio active unknown time, Mobile
radio active adjusted time, Signal scanning time)
Wifi
- Modification of field names to improve clarity
- Removed count "x" values

Test: manual - flash build, reset batteryStats, use device > 1 hr
with alternating pattern between screen on/off/AOD. Dump stats, check
all screen related stats look normal, esp. record matches actual time
spent in each screen state. In raw bugreport:
Search "amount discharged" for % discharge;
Search "Screen on/off/doze discharge" for mAh discharge;
Search "time on battery" for up/real time in each state.
Test: Added two unit tests for note AOD screen state

RPM = resource power manager.
Fetching the rpm stats (specifically, the subsystem low power stats) is
slow... too slow to reasonably do each time the screen state changes.
Therefore, it is disabled until fetching this information can be done
more quickly. Consequently, the screen-off RPM values will be incorrect
until it is re-enabled; they are therefore not printed.

Currently Resource Power Management (e.g. VMIN time) is reported in the
batterystats history each time the battery level changes. We need this
information in the batterystats checkin, and need to be able to
differentiate time spent in each power state/voter, total as well as
when the screen is off.
The RPM information is obtained via a JNI call to the appropriate HALs.
Batterystats report version is increased to 26.

Some things really need to be tuned in order to not annoy users, and
should otherwise be turned off. Let an effect state whether it should
fallback to a generic effect or should just be silent if there's no
hardware specific version of it.

Currently, we only count add tethering traffic to per-UID
stats, but not to total data usage (i.e., dev and XT stats). This
is correct for software tethering, because all software forwarded
packets are already included in interface counters, but it is
incorrect for hardware offload, because such packets do not
increment interface counters.
To fix this:
1. Add an argument to ITetheringStatsProvider#getTetherStats to
indicate whether per-UID stats are requested. For clarity,
define integer constants STATS_PER_IFACE and STATS_PER_UID
to represent these operations.
2. Make NetdTetheringStatsProvider return stats only if per-UID
stats are requested. (Otherwise tethering traffic would be
double-counted).
3. Make OffloadController's stats provider return the same
stats regardless of whether per-UID stats were requested or
not.
4. Make NetworkStatsService add non-per-UID tethering stats to
the dev and XT snapshots. The per-UID snapshots were already
correctly adding in per-UID stats.
