adbd on device kicks the usb connection when usb IO fails. But to notify
adb on host to reconnect it, adbd needs to close ep0 to reset the usb
connection. Otherwise, adb on host cann't connect the device unless the
usb cable is reconnected or adb host server is restarted.
This can be tested by using `adb reconnect device` command.

(cherry picked from commit 69e97e4bee)
close_all_sockets was assuming that all registered local sockets used
local_socket_close as their close function. However, this is not true
for JDWP sockets.

sockets.cpp was branching on whether a socket close function was
local_socket_close in order to avoid a potential deadlock if the socket
list lock was held while closing a peer socket.

adb implements its own file descriptor emulation layer on Windows,
which requires the use of adb_close instead of close throughout the
codebase. Add a template argument to unique_fd that allows for this.

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.

Test: python -m unittest discover
Test: adb_test
Test: `adb forward` and `adb reverse` with tcp:0

https://android-review.googlesource.com/#/c/210646/ added a
has_shell_protocol() function but the test_device.py tests were still
trying to use the now-missing SHELL_PROTOCOL_FEATURE constant.
This CL just switches test_device.py to correctly use the
has_shell_protocol() method.
Change-Id: Ie0a2f0dc07529843d25051a01e08fb677551a4e1
Test: `python -m unittest discover -v` on devices with and without
the shell protocol.
On mac, if the adb server kicks a transport on some error, mac usb driver
will not report a new usb device. So instead of relying on mac usb driver
to report new usb devices, this CL uses a loop to search for usb devices
not exist before. Note that this is also the behavior on windows and linux
host.
`adb reconnect` can be used to verity this CL.

128 maximum FDs is a pretty low limit, which can easily be exhausted by
port forwarding. Bump the maximum up to 2048, and add a test that checks
whether we can actually use a few hundred sockets.

Problem: For devices using /dev/usb-ffs/adb, Run
`while true; do adb reconnect device; sleep 1; done`. And the
device soon becomes offline. The adbd log shows that calling
adb_read(h->bulk_out) in usb_ffs_read() gets EOVERFLOW error.
Reason: When kicking a transport using usb-ffs, /dev/usb-ffs/adb/ep0
is not closed, and the device will not notify a usb connection reset
to host. So the host will continue to send unfinished packets even
if a new transport is started on device. The unfinished packets may
not have the same size as what is expected on device, so adbd on
device gets EOVERFLOW error. At the worst case, adbd has to create new
transports for each unfinished packet.
Fixes:
The direct fix is to make the usb connection reset when kicking transports,
as in https://android-review.googlesource.com/#/c/211267/1. And I think
we can make following improvements beside that.
1. Close a file that is used in other threads isn't safe. Because the file
descriptor may be reused to open other files, and other threads may operate
on the wrong file. So use dup2(dummy_fd) to replace close() in kick function,
and really close the file descriptor after the read/write threads exit.
2. Open new usb connection after usb_close() instead of after
usb_kick(). After usb_kick(), the transport may still exist and
reader/writer for the transport may be still running. But after
usb_close(), the previous transport is guaranteed to be destroyed.

adb: after `adb root`, wait for the device in any state.
adb: add support for 'wait-for-any'.
adb: make 'wait-for-{recovery,sideload,bootloader} work.
The help for wait-for-* documents this as working, but we only had a
special case for 'wait-for-device'. Make the others work as well.

Add reconnect command for debugging. `reconnect` kicks a transport
from the host side, `reconnect device` kicks a transport from
the device side. They can be used to produce transport errors.

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.
