The current fastbootd only supports USB protocol. But some Android TV
devices are built without USB port. The fastbootd cannot be used on
those ATV devices due to it.
This change adds TCP protocol for such devices and fastbootd.protocol
property is added to control which protocol to use.

UDP fastboot will require re-transmission in the case of datagrams
getting lost. This CL adds Socket functionality to easily distinguish
between a normal timeout and a socket failure.
I also found some Windows docs that indicate sockets may become
invalid after a call to recv() times out. This has never occurred in
my testing, but to be safe this switches the timeout implementation
to use select() instead of SO_RCVTIMEO.

Fixes libcutils multi-buffer write interface to be more friendly and
hooks into it from the fastboot Socket class.

(This code was originally part of a huge fastboot CL but has been split
out to try to make the CLs a little more manageable).
More prep for fastboot TCP and UDP implementations. This CL adds a
SocketMock class that makes it easy to mock out network behavior so we
can unit test the TCP and UDP protocols.
Also uses the new libcutils socket_get_local_port() to avoid hardcoding
a server port in unit tests.

Now that cutils has cross-platform socket functionality, we can
restructure fastboot to remove platform-dependent networking code.
This CL adds socket_set_receive_timeout() to libcutils and combines the
fastboot socket code into a single implementation. It also adds TCP
functionality to fastboot sockets, but nothing uses it yet except for
the unit tests. A future CL will add the TCP protocol which will use
this TCP socket implementation.
