When apps try to call factoryReset to do networking reset, it
will result in updating the setting in SettingsProvider.
ContentProvider will verify if the package name of the caller
that initiated the request being processed on the current thread.
The package should belong to the calling UID. The setting update
started from the ConnectivityService context, so the package will
be android but the calling UID will be the calling app. It will
cause a SecurityException. The behavior is fine previously as its
known caller(Settings) shares system UID. But it will be a
problem for other callers, such as CTS. Thus, clear the identity
since the necessary permission check should be examined at the
top of the method. The following actions should be fine to be
proceed from the system itself. Also replace the user restriction
check via hasUserRestrictionForUser with the UserHandle created
from the calling uid to ensure it's verified with correct user.

The legacy design of "dumpsys connectivity" will only dump
information with NORMAL priority. It was updated to provide
both NORMAL and HIGH priority information in order to support
dump in bugreport. However, it will also affect the result

* changes:
  Make VcnTransportInfoTest pass on AOSP.
  Immediately redact VcnTransportInfo.
  Do not automatically redact TransportInfo objects.

This patch introduces the concept of a network offer that
providers send to Connectivity to register for relevant
requests. This lets them see only requests that they can
hope to satisfy considering their capabilities and score
filters.

This is meant to replace the filtering mechanism currently
implemented by NetworkFactory. The reason for replacing
this mechanism is that the old mechanism does caps and
score filtering on the factory side, which requires these
two filters to be contextless and available system-wide,
including in separate processes from the system server.
These constraints severely limit and complexify in
particular what the score comparisons may look like. In
the past the score comparison was only integer-based,
making the code duplication not much of a problem, but as
this scheme is becoming unsustainable by spreading the
complexity of the selection across the entire stack, a
centralized mechanism is now necessary.

This patch only introduces the new objects and has CS
keep track of them, but does not actually use them yet.
Followup patches will implement the logic of calling
the offer callbacks.

Currently, NetworkCapabilities always redacts the TransportInfo
objects it contains whenever a defensive copy is made. This makes
it impossible to make a defensive copy on a TransportInfo
parcelled from another process without redacting it.

Stop redacting by default; instead rely on ConnectivityService
explicitly calling NetworkCapabilities' redacting constructor
when it returns a NetworkCapabilities object to an app via a
callback or synchronous call. This is currently done by
- createWithLocationInfoSanitizedIfNecessaryWhenParceled, which
  is called from callCallbackForRequest, getNetworkCapabilities,
  and getDefaultNetworkCapabilitiesForUser.
- getNetworkCapabilitiesWithoutUids, which is used when sending
  ConnectivityDiagnosticsManager callbacks. In this method,
  unconditionally redact all information, which is what the code
  did previously due to the default redaction setting for empty
  NetworkCapabilities objects being REDACT_ALL.

Move the tests together with packages/Connectivity code, so both can be
moved to packages/modules/Connectivity together.

Also reorganize unit tests in a unit/ directory, as other tests
(integration/, common/ etc.) have been added in tests/net since they
