Hooks the ConnectivityManager.TYPE_MOBILE_EMERGENCY,
PhoneConstants.APN_TYPE_EMERGENCY, and NetworkCapabilities.NET_CAPABILITY_EIMS

This got lost in the multinetwork work for L. It means
that if telephony stops having the ability to pass packets for a while
the rest of the platform doesn't know.
Telephony enters the suspended state if it enters a telephony call
while using certain radio access technologies, or if it switches to
one of those RATs while in a call. It also can enter this state if
it temporarily loses contact with the network - the modem will
not report the loss of the data call for an indeterminant time in
the hope that regaining the network will restore the connection
without harm to any ongoing ip layer interactions. For example
passing through a tunnel or taking an elevator trip may use this
mechanism.

Move reachable DNS server computation out of ConnectivityService

Restore previous ConnectivityService#updateDnses() behaviour, as

It's not clear what it means to request a network with a mutable
NetworkCapability like NET_CAPABILITY_VALIDATED or
NET_CAPABILITY_CAPTIVE_PORTAL. Presently requesting such a network
would fail in a number of different ways:
1. The NetworkFactories would fail to match the request against their
filter which doesn't include stateful NetworkCapabilities.
2. If the NetworkFactories did match, they'd bring up networks to try
and satisfy the requests, but the networks would not have any
mutable NetworkCapabilities initially so they'd be reaped.
Because of these problems it's safest to simply disallow these
requests.

Without this API we're more or less encouraging apps to have long running
processes (battery draining) to receive NetworkCallbacks for the stateful
NetworkCapabilities NET_CAPABILITIES_VALIDATED and
NET_CAPABILITIES_CAPTIVE_PORTAL. With this API they can instead using
PendingIntents which outlive their apps.

Per UX, default strings should have space between value and units
resulting in "12.3 GB". Add a formatting variant that returns the
various components for callers who want to build their own strings.
For now there is only one mounted emulated volume at a time, and
it's always the primary storage, so give it the default rootId to
keep old Uris working.

- There are no callers of
NetworkInfo.setIsConnectedToProvisioningNetwork(), so remove all the
code that deals with mIsConnectedToProvisioningNetwork being true,
including the two ConnectiviyManager APIs.
- There are no callers of
ConnectivityManager.getMobileRedirectedProvisioningUrl(), so remove
the code that reads this URL.
- There are no callers of
ConnectivityManager.captivePortalCheckCompleted(), so remove this
API which is currently a no-op.

The API review comments in http://b/21343774 point out that the
suggested use case for onPreCheck (captive portal login apps) is
not a good use case as it requires that the app always be
running.
Also, unhide NET_CAPABILITY_VALIDATED, which is useful to apps
that want to detect captive portals and network connectivity
failures.

Code that uses android.system.Os to create sockets as FileDescriptors
should be able to bind them to networks. Note that FileDescriptors
could already be marked as "protected from VPNs" via
NetworkUtils#protectFromVpn(), but heretofore were not easily bound
to any particular network.

With NLM_F_ACK set in RTM_NEWNEIGH requests we get some response from
the kernel, whether there was an error or not.
Additionally:
[1] add IpReachabilityMonitor#probeNeighbor() as a public
static method, since it actually depends very little on the
class internals and might be of larger use.
[2] add a unittest for parsing NetlinkErrorMessages.

than lingering until the next random netlink neighbor multicast message
arrives.
Additionally, add a small unittest to verify that multiple calls to
NetlinkSocket#close() are safe.

It was deprecated as part of the Apache deprecation, however it is used
by ConnectivityManager.getLinkProperties() and .getDefaultProxy().
The alternatives (e.g. java.net.Proxy) do not offer a complete
replacement as they lack certain fields (e.g. PAC URL).

1. Always keep ConnectivityService's validated bits current:
- Apply the validated bit whenever a NetworkAgent updates its
NetworkCapabilities.
- Set or clear the validated bit whenever lastValidated changes.
2. Send callbacks when the validation state of a network changes.
3. Delete getNetworkCapabilitiesAndValidation, removing code
duplication with getNetworkCapabilities.
4. Add the validated bit to NetworkCapabilities#toString.
