vsock is a socket address family for communicating into and out of
virtual machines. Addresses have a port and CID. The CID is unique to
each virtual machine on the computer. The VM host always has CID 2.
http://man7.org/linux/man-pages/man7/vsock.7.html
Inside the android guest, the adb daemon hosts a vsock server with
VMADDR_CID_ANY, automatically using the guest CID. The adb server
can now connect to addresses of the form vsock:cid:port, where the CID
must be specified and the port defaults to 5555.
This is a significant speed improvement for ADB connections in
Cuttlefish, with 150-200 MB/s for `adb push` and 100-150 MB/s for
`adb pull`. It also allows removing some proxying steps from Cuttlefish,
simplifying the full connection path, and removes a dependency on the
unstable ivshmem protocol.
Commands tested against a Cuttlefish VM with CID 3:
adb connect vsock:3:5555
adb -s vsock:3:5555 shell
adb disconnect vsock:3:5555
Supporting "adb disconnect" and "adb -s" required modifying some of the
parts that parse addresses / serials.

The listen backlog seems to be more meaningful on Darwin than on Linux,
resulting in connections failing with ECONNRESET. Bump it up to the
maximum supported value to make this less likely. 128 pending
connections ought to be enough for anybody.

Add an implementation of std::make_unique for Windows, where we're
currently stuck with C++11, and switch some uses of new over to it.

Misconfigured systems can have localhost pointing to an address that
isn't 127.0.0.1 or ::1.
adb is the only caller of the libcutils socket_loopback functions, so
move them into adb and switch the implementations over to using
INADDR_LOOPBACK and in6addr_loopback, instead of resolving 'localhost'
when connecting.

We use <sys/stat.h> mode macros on the host to parse modes sent over
from the device, so they had better match. Add static_asserts to ensure
this.
(Also, fix the cases where they don't.)
Test: mma -j48, compiled the static_asserts on darwin manually

stat on Windows fails with ENOENT when passed a path with a trailing
slash or backslash, regardless of whether the target is actually a
directory. Emulate the correct POSIX behavior by stripping trailing
path separators and then checking if the target is a directory if
successful.

Previously we loop through local ports every second, this patch improves
the strategy by retrying only just disconnected emulators.
