In current design, entries with zeros are preserved after
addition/subtraction. These entries are not very useful
and lead to difficulty of verifying the result of
addition/subtraction.
However, change the behavior in the original NetworkStats
is considered risky in current stage.
Thus, this change provide a function that could remove these
empty entries in tests.

Switch on the recording in device side. Metrics will be
collected in follow-up patches which can be independently
enabled/disabled.
This change also fix the fail in NetworkStatsCollectionTest
which caused by enabling this feature, where the rounding
problem happened when records are distributed into smaller
buckets and categorized into more NetworkIdentity.

Previously network stats could be recorded by different rat type.
However, the feature was disabled by ag/173504 since rat type
frequently flapping between HSPA+ and UMTS.
Given that this feature might be useful for collecting metrics,
re-implement it based on current architecture and reduce the
overhead introduced by frequently flapping by:
1. only react when rat type changes between 2G/3G/4G/5G.
2. reduce the number of records by only recording a subset
of rat type that represented for a given network class.
3. enforce 1 second rate limit if flapping too much.
Note that the feature is still disabled but will be enabled
in follow-up patches.

Currently, in NetworkStats, there are many methods to manipulate
the records. However, some methods are similar and ambiguous,
such as addEntry, addValues, setValues, addIfaceValues,
combineValues and combineAllValues.
Thus, properly grouping and renaming methods are necessary.
In this change, for methods that add one record conditionally,
name them addEntry.
addValues -> addEntry

IpServer would throw
IllegalStateException("start() called from off-thread")
2. Ethernet tethering request may be duplicated if multiple

Currently, registerNetworkStatsProvider requires the
UPDATE_DEVICE_STATS permission. This is a privileged permission
so it can be granted to preinstalled apps. Thus, apps like
GmsCore, or preinstalled apps will be able to update network stats.
This change checks for a new permission that would only allow
signature apps to declare that. Also check
MAINLINE_NETWORK_STACK permission to allow NetworkStack process
to use it.

(clean cherry-pick from internal branch)
Just because the bucket is active (ie. overlaps with 'now') doesn't
mean the request necessarily covers the entire bucket.
For example a bucketDuration=5 with a bucket from curStart=1 to
curEnd=6 with now=4 and requests:
- from start=0 to end=3 --> overlap=[1,3] --> bucketSpan=2
- from start=2 to end=3 --> overlap=[2,3] --> bucketSpan=1
- from start=2 to end=5 --> overlap=[2,4] --> bucketSpan=2
- from start=2 to end=7 --> overlap=[2,4] --> bucketSpan=2
and the previously correctly handled cases:
- from start=0 to end=5 --> overlap=[1,4] --> bucketSpan=3
- from start=0 to end=7 --> overlap=[1,4] --> bucketSpan=3
We fix this by bounding the end of buckets to now, this means
that bucketDuration is no longer a constant, but it simplifies
all the rest of the logic.
