This change is in preparation to allow the TCP-based transports to be
able to reconnect. This is needed because multiple threads can access
the Connection object. It used to be safe to do because one instance of
atransport would have the same Connection instance throughout its
lifetime, but now it is possible to replace the Connection instance,
which could cause threads that were attempting to Write to an
atransport* to use-after-free the Connection instance.

Rename the existing Connection to BlockingConnection, add a nonblocking
Connection, and add an adapter between the two, to enable future work
to reduce the impedance mismatch from implementing a blocking interface
on top of nonblocking primitives.
While we're here, delete A_SYNC, and remove one layer of pipes when
sending a packet (replacing it with a condition variable when using
BlockingConnectionAdapter).

As step one of refactoring atransport to separate out protocol handling
from its underlying connection, extract atransport's existing
hand-rolled connection vtable out to its own abstract interface.
This should not change behavior except in one case: emulators are
now treated as TCP devices for the purposes of `adb disconnect`.

adbd currently decides to use the QEMUD pipe if ro.kernel.qemu=1, as set
for ranchu. The Android container in Chrome OS doesn't have that
property set and it can't be set to 1 because it's used as equivalent to
"runs inside an emulator" throughout Android and changes the way
graphics are handled, whether Bluetooth is supported, etc., behaviour
that we do not want to trigger in Chrome OS.
adbd now also checks service.adb.transport to decide whether to use the
QEMUD (goldfish) pipe.
adbd still first checks for ro.kernel.qemu to preserve existing
behaviour and will still fallback to TCP if it can't use Goldfish.

When device goes offline, user usually has to manually replug the
usb device. This patch tries to solve two offline situations, all
because when adb on host is killed, the adbd on device is not notified.
1. When adb server is killed while pushing a large file to device,
the device is still reading the unfinished large message. So the
device thinks of the CNXN message as part of the previous unfinished
message, so it doesn't reply and the device is in offline state.
The solution is to add a write_msg_lock in atransport struct. And it
kicks the transport only after sending a whole message. By kicking
all transports before exit, we ensure that we don't write part of
a message to any device. So next time we start adb server, the device
should be waiting for a new message.
2. When adb server is killed while pulling a large file from device,
the device is still trying to send the unfinished large message. So
adb on host usually reads data with EOVERFLOW error. This is because
adb on host is reading less than one packet sent from device.
The solution is to use buffered read on host. The max packet size
of bulk transactions in USB 3.0 is 1024 bytes. By preparing an at least
1024 bytes buffer when reading, EOVERFLOW no longer occurs. And teach
adb host to ignore wrong messages.
To be safe, this patch doesn't change any logic on device.

Traditionally, qemu_pipe has both the declaration and implentation of each
function in one header file--qemu_pipe.h, and it is getting incovenient to
maintain.
This CL separates the implementation of functions from the header file,
and makes qemu_pipe a static library for other modules to link to.
Note that the interface and implementation of qemu_pipe are kept unchanged,
and future CLs will enhance the implementation to make it more reliable and
more compatible with old and new API levels.
Following projects are affected by this refactoring, and they are modified
accordingly:

There are two lists of active ADB transports (devices),

This CL more conservatively checks if there are no

The <hardware/qemu_pipe.h> header isn't related to any loadable
hardware module, this patch thus relocates it to <system/qemu_pipe.h>
which is a much more logical location.
Note the following changes:
- The pipe name must begin with the 'pipe:' prefix to avoid an
un-necessary snprintf() and buffer copy.
- Does not probe for the obsolete /dev/goldfish_pipe device, i.e.
only use /dev/qemu_pipe instead.
- Use QEMU_PIPE_DEBUG() instead of D() as the debugging macro.
+ Update ADB to use the newest <system/qemu_pipe.h>
+ Add qemu_pipe_frame_send() and qemu_pipe_frame_recv() utility
functions which replace the obsolete qemud_channel_send() and
qemud_channel_recv() from the defunct <hardware/qemud.h>
header.

ADB local transport for the emulator based on qemu pipes uses a socket
transport. Before this CL, multiple connection requests accepted by the
qemu pipe device would result in ADB transport with the same serial.
The register function would fail as a result, and all subsequent
connections would fail.
Test:
while true; do adb kill-server; adb devices; done
Doesn't fail for > 10 minutes.
This CL replaces an earlier CL
(I0fdcf2694516151c5f8f8e1580648b940679c981) that was unsafe for real
devices.
