Add a protectFromVpn method that takes a FileDescriptor
DHCP: protocol changes.
DHCP: glue code.
DHCP: Ethernet/IP packet header changes.
DHCP: Minor cleanups to the packet code.
DHCP: Move the packet code to frameworks/base/services.
DHCP: Add a native method for making a DHCP socket.
DHCP: Add a superclass for DhcpStateMachine.

The behaviour of the client is intended to mirror the behaviour
of the current DhcpStateMachine + dhcpcd combination, except it
does not store leases across network changes.

1. Define and add parsing code for MTU, max message size, T1, T2.
2. Add common TLVs (message size, hostname, vendor ID) to all
packets sent by the client.
3. Don't include requested IP and server ID in renew messages,
since the RFC says MUST NOT.
4. Don't hardcode the broadcast flag to true in DISCOVER packets,
use what the caller passed in.
5. Make some methods static.

1. Add a method to make a DhcpResults object from a DHCP packet.
2. Add a method to fetch the client MAC from the packet. This is
needed to check that the message is for us (lots of DHCP
messages are broadcast).
3. Add a length argument to the method that parses DHCP packets,
so the caller can use the same MTU-sized array all the time
instead of having to pass in a new array for every packet.

Change-Id: I58223f5ec90fb5c762bc2934649e02f9122018b2
1. Support L2_ENCAP when building packets as well as when parsing.
2. Skip IP options when parsing DHCP packets.

Change-Id: Ic27a45790ed1cf7cf5b82d63b6c0b64c909a570f
1. Delete the DhcpStateMachine, since we don't plan to use it.
2. Make all InetAddresses Inet4Addresses, since that's what they
are. In order to do this, define INADDR_ANY and
INADDR_BROADCAST, constants, since Inet4Address.{ANY,ALL} are
not Inet4Addresses but InetAddresses.

There's no need for it to be in frameworks/base/core, since it
will only be used by services.

This can be used to switch between different DHCP client
implementations. The caller can declare objects of type
BaseDhcpStateMachine, and call its methods, without needing to
care what implementation is in use.
Bug: 19704592
Change-Id: Icefad9b0d0f83b349681388b1fa16b5e2e37c042
1. Add a validating method to convert a netmask to a prefix length.
2. Add a function to get the implicit netmask of an IPv4 address.
3. Add a unit test.
Bug: 19704592
Change-Id: Icb9f58d3903ea01df9e3720383c9bd5db6dd8f26
This is a temporary fix to prevent deadlocking in the
system. Need to come up with a better solution for
accessing WiFi and other subsystems from BatteryStats.

Change-Id: I464e7490c9780249d2a3eef05ce084a7d84372c0
Allows playback/TV device to use the API to turn off
TV/other device that accepts the command.
