5c4bddb8cd [NS A20] Cleanup
A lot of this code can't be triggered at all.
• newNetwork.created in l.6488 is implied by newNetwork.everConnected
  in l.6357
• !newNetwork.isVPN() in l.6488 is implied by the fact that VPNs are
  always foreground, so oldPermission can't != newPermission in l.6488
• updateUids in l.6502 is useless because uids can't change during a
  rematch (because there is no code doing that). Metered state and
  roaming state similarly can't change during a rematch, so
  meteredChanged and roamingChanged are always false
• updateAllVpnCapabilities in l.6537 is useless because VPN do not
  inherit the foreground state of their underlying networks, which
  would be the only reason to call that in l.6537
• Object.equals() in l.6480 is necessary false because at this line
  it is known that the foreground state has changed, which must have
  caused the NET_CAPABILITY_FOREGROUND to be different, so the objects
  can't be equal

8e96a75543 Replace the permission of internal connectivity checks
A number of connectivity checks that protect system-only methods
check for CONNECTIVITY_INTERNAL, but CONNECTIVITY_INTERNAL is a
signature|privileged permission. We should audit the permission
checks, and convert checks that protect code that should not be
called outside the system to a signature permission. So replace
all CONNECTIVITY_INTERNAL to other proper permissions.

f01b2efc13 [NS A13] Move legacy broadcast handling after rematch.
As opposed to other patches in this series, there is a logic change
here. This will send all necessary legacy broadcasts after all
matches have been done.

This should be fine because the callbacks and the broadcasts are
unordered anyway, and the broadcasts are still sent in the same
order as before ; there should not be an observable change from
apps besides some jitter.

61c79256b1 [NS A12] Move some legacy type tracker handling to a function
It's fine to do this out of the if() clause because :
• If the network newly satisfies a request it is sure to have
  it in the list of requests it satisfies
• If it does not newly satisfy a request and there is still
  a request with a legacy type that it satisfies, then it
  is already remembered by LegacyTypeTracker

As for the VPN, the code always enters the condition anyway.

9b2c01a7f0 Fix hasUseBackgroundNetworksPermission issue.
PermissionMonitor#hasUseBackgroundNetworksPermission only uses
the first package name of the uid for checking permission.
This is incorrect since each package declared different
permissions. So using the mApps which already checked both
network and using restricted network permissions. If uid is in
the mApps list that means uid has one of permission at least.

784ca66669 Fix title of PRIVATE_DNS_BROKEN notification when connecting VPN
NetworkNotificationManager will only get the first transport
type from the NetworkCapabilities of network, and if the device
connects to a VPN and its underlying network is wifi, then the
first finding transport type will be TRANSPORT_WIFI. So, if the
private DNS is broken when device connected to VPN,
NetworkNotificationManager will try to get the SSID for the
title of notification but failed. For this kind of case, the
title of PRIVATE_DNS_BROKEN notification will show
"null has no internet access".

ef365c70c9 [NS A03] Remove mNetworkForRequestId
The goal of doing this is to remove the locks. Locking imposes
an ordering that is parallel to the program sequence ; often
it is what is needed, but the refactoring in progress needs to
change the traversal order of the requests without having
observable side-effects (or at least, very controlled ones).
The order is difficult enough to maintain when there is
only one. In this case, it is easy to remove the locks, and it
will simplify vastly the complexity of the refactoring by
removing the parallel ordering that would have to be maintained.
