NB: We decided to not sniff for the constant saved __ashmem_rdev in
the early error path; requiring either the use of atomic operations,
or acquiring a lock to do it correctly. The heroics are not worth it.

This CL implements a TCP protocol for use with fastboot. Protocol
description is given in fastboot_protocol.txt, some examples of
expected behavior can also be found in tcp_test.cpp.
Usage is:
fastboot -s tcp:<hostname>[:port] <command>

- collect st_rdev on open, or when required, for /dev/ashmem.
- check in all cases if fd is a character device and matches rdev.
- requires that we have open, read and write access to /dev/ashmem
to check, assumption being that if we can not, then we have no
right playing with the associated misdirected file descriptor.
NB: ashmem libcutil library entry points can no longer be called in
signal context.

Fixes SocketMock::ExpectSendFailure() to allow unit testing of errors
during send, and adds tests for ExpectSendFailure() and
AddReceiveFailure().
Also adds missing tests to make sure ReceiveAll() continues to read
until failure or all bytes have been read.

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

strdup to a static pointer is unnecessary, strlcpy into a static buffer
instead. Avoids allocations in the ALOG* path, allowing liblog to be
used by libmemleak.

- sort header order and in groups
- remove all tabs, use only spaces
- use TEMP_FAILURE_RETRY in system calls
- preserve errno for -1 return

(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.

Unix and Windows both have functions to write multiple buffers to a
socket with a single call but they have very different signatures. This
CL creates some cross-platform functions to be able to perform these
operations in a uniform way, which will be required for upcoming
fastboot functionality.
This CL also fixes some inconsistent spacing in the touched files.

Note that with this change the linker will ignore
icu libraries provided by an app because public
libraries are always provided by system. At this point
it does not affect any apps because before Marshmallow
all of them were getting platform version of icu4c
libs anyways (they will be getting their own copy of the
library only in Marshmallow release).

Tests that require a local server currently hardcode a test value,
which can run into conflicts depending on what's currently running on
the machine.
This CL adds socket_get_local_port(), which lets us pass 0 so the
system picks an open port and we can query which port it chose.
