fastboot: add Socket timeout detection.
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.

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

fastboot: socket testing improvements.
(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.

fastboot: use cutils socket functions.
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.

fastboot: implement UDP networking interface.
This CL creates a UdpSocket class that provides a simple unified
interface to send and receive UDP packets for all platforms. Nothing
uses this interface yet except for tests.
The eventual goal is to implement a UDP protocol for fastboot, but it
makes the code much simpler and more modular if we handle the low-level
networking here independently of our custom fastboot protocol.
Some of the Windows code is similar to adb. I'd like to create a
library to hold the common functionality, but it is going to be a
little delicate to separate out the features unique to adb (e.g. the
custom file descriptor system), and I don't want to risk breaking
something in adb before the holiday break, so I'm hoping to get this in
for now and merge them early next year.
Tests are included in this CL to exercise this functionality using a
loopback connection.
Bug: http://b/26154763.
Tests: `fastboot_test` loopback tests on Linux, Mac, and Windows 7.
