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.
