Move the invocation of adb_notify_device_scan_complete to
the end of device_connected, where we decrement connecting_devices.
Also, create a dedicated thread for handling hotplug events, instead of
reusing the main thread for this, since the main thread blocks until
device scan is complete.

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.

This CL adds support to forward or reverse TCP port 0 to allow the
system to automatically select an open port. The resolved port number
will be printed to stdout:
$ adb forward tcp:0 tcp:8000
12345
$ adb reverse tcp:0 tcp:9000
23456
This allows testing to be more robust by not hardcoding TCP ports which
may already be in use.
Forwarding port 0 is a host-only change and will work with any device,
but reversing port 0 requires the device to be updated with a new adbd
binary.
This CL also does a little bit of cleanup such as moving the alistener
class out of adb.h, and adds some error checking and additional tests.

Pulls the Windows error string generation out of adb into libbase so
that it can be used by fastboot as well. Also makes a Unix equivalent
that just wraps strerror() so that upcoming fastboot error reporting
code can be platform-independent.
The intent here is just to provide a portable way to report an error to
the user. More general cross-platform error handling is out of scope.

This CL moves the network address parsing function from adb to libbase
so that it can be used by fastboot as well as adb.
libbase seemed like the right choice because:
1. It already has some parsing functions (parseint)
2. The net address parsing function uses the libbase string
functions so we have a libbase dependency anyway.
The parsing function has been modified slightly to make the canonical
address optional, and debug logging on success has been removed.
For adb the only functional difference is that parsing a network
address will no longer print the result to the debug log, which seemed
unnecessary.

Background
==========
On Windows, if you run "adb shell exit" in a loop in two windows,
eventually the adb client will be unable to connect to the adb server. I
think connect() is returning WSAEADDRINUSE: "Only one usage of each
socket address (protocol/network address/port) is normally permitted.
(10048)". The Windows System Event Log may also show Event 4227, Tcpip.
Netstat output is filled with:
# for the adb server
TCP 127.0.0.1:5037 127.0.0.1:65523 TIME_WAIT
# for the adb client
TCP 127.0.0.1:65523 127.0.0.1:5037 TIME_WAIT
The error probably means that the client is running out of free
address:port pairs.
The first netstat line is unavoidable, but the second line exists
because the adb client is not waiting for orderly/graceful shutdown of
the socket, and that is apparently required on Windows to get rid of the
second line. For more info, see
https://github.com/CompareAndSwap/SocketCloseTest .
This is exacerbated by the fact that "adb shell exit" makes 4 socket
connections to the adb server: 1) host:version, 2) host:features, 3)
host:version (again), 4) shell:exit. Also exacerbating is the fact that
the adb protocol is length-prefixed so the client typically does not
have to 'read() until zero' which effectively waits for orderly/graceful
shutdown.
The Fix
=======
Introduce a function, ReadOrderlyShutdown(), that should be called in
the adb client to wait for the server to close its socket, before
closing the client socket.
I reviewed all code where the adb client makes a connection to the adb
server and added ReadOrderlyShutdown() when it made sense. I wasn't able
to add it to the following:
* interactive_shell: this doesn't matter because this is interactive and
thus can't be run fast enough to use up ports.
* adb sideload: I couldn't get enough test coverage and I don't think
this is being called frequently enough to be a problem.
* send_shell_command, backup, adb_connect_command, adb shell, adb
exec-out, install_multiple_app, adb_send_emulator_command: These
already wait for server socket shutdown since they already call
recv() until zero.
* restore, adb exec-in: protocol design can't have the server close
first.
* adb start-server: no fd is actually returned
* create_local_service_socket, local_connect_arbitrary_ports,
connect_device: probably called rarely enough not to be a problem.
Also in this change
===================
* Clarify comments in when adb_shutdown() is called before exit().
* add some missing adb_close() in adb sideload.
* Fixup error handling and comments in adb_send_emulator_command().
* Make SyncConnection::SendQuit return a success boolean.
* Add unittest for adb emu kill command. This gets code coverage over
this very careful piece of code.

I'm deleting my own comment here about always returning "unknown"

It is possible that the adb server on host has many sockets in
CLOSE_WAIT state. To prevent socket leak, always enable POLLRDHUP
in fdevent.cpp to detect sockets in CLOSE_WAIT state.
Update LocalSocketTest unit tests:
Change half_close_with_packet to read_from_closing_socket, as reading
from a SHUT_WR socket is not needed in adb.
Change close_with_no_events_installed to close_socket_in_CLOSE_WAIT_state,
as the latter is more close to the real situation in use.

Previously the transport features list was only overwritten if a
new feature list was found. However, adbd can reuse the same atransport
object even if the adb server is killed and restarted, so the feature
list was not cleared properly if the newly started adb server didn't
provide one.
This CL fixes the bug by clearing the transport features list whenever
a connection banner is parsed.

Adds -T (no PTY) and -t (force PTY) options to `adb shell` to mimic
ssh options. Small cleanup to send an entire FeatureSet to the adb
client at once to avoid multiple round-trips when querying multiple
features.
Known issue: humans using `adb shell -T` to start a non-PTY interactive
session may experience problems since neither side will have PTY
features like echoing or newline translation. This is probably OK for
now as the -Tt options are primarily useful for scripting.

On Windows 7, GetStdHandle() may return console pseudo-handles. If you
call SetHandleInformation(h, HANDLE_FLAG_INHERIT, 0) on such a handle,
it will fail. These failures should be ignored like the old code.
Newer versions of Windows return real handles that don't have this
issue. Console pseudo-handles can apparently be identified by the values
3, 7, 11.
This is a regression from 2122c7a148.
