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.

`adb install` was writing success to stderr rather than stdout.
Server mismatch messages were going to stdout rather than stderr.
Error messages should consistently start with a lower case letter.
Also improve consistency of syntax error reporting.

From the bug:
Say we run a new adb against an old device (like KitKat). Even with a new
client ADB, in this configuration, "adb shell" will create a remove tty
unconditionally. So if the user runs "adb shell -t -t", we shouldn't fail
with a message about the remote device not supporting -tT options --- the
user asked to create a tty unconditionally, and since we're going to create
a tty unconditionally, we should just succeed. (That it's going to succeed
due to protocol inadequacy instead of succeeding on purpose is irrelevant.)
That adb fails in this case makes scripts more complicated, since they can't
just pass "-t -t" unconditionally if they want a tty and to work on all
device versions, even if the script requires a new-ish adb locally.

Some POSIX-only files would like to use functions declared in
adb_utils.h without being forced to use the sysdeps stuff for open,
close, etc. Extract the adb-specific unique_fd into its own header so
those files can use adb_utils.h alongside the real unique_fd.

Starting on Android N, zipped bugreports contain more information than
flat-file, text bugreports. On N, calls to 'adb bugreport' would still
generate a flat-file bugreport, but with a warning.
With this change, 'adb bugreport' will generate a zipped bugreport in
the current directory, using the bugreport name provided by the
device. Similarly, calling 'adb bugreport dir' will generate a bugreport
with a device-provided name, but in such directory.

bugreport() will be soon refactored to track progress, which will
require more comprehensive unit tests.
As such, it's better to move it to its own files, which in turn also
requires moving send_shell_command() and usage() to commandline.h.

adb install-multiple makes a minimum of 3 calls to the 'pm' command. This
causes at least 3 separate "pm" processes to be spun up. Instead, use the

`adb root` would hang for devices connected over TCP/IP, because they
never come back. Unfortunately, there doesn't seem to be an easy way to
find out what we're talking to, so replace it with a long sleep for now.

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.
