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.

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.

Dumpstate now supports zipped bugreport, whose output is more complete
than the flat-file bugreports provided prior to N. As such, adb now has
a 'adb bugreport <ZIP_FILE>' name whose implementation:
- Calls the new bugreportz binary.
- Parses its output, which in case of success is the path of the .zip
file.
- Pulls the device file and renames it according to the command-line
argument.

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.

(cherry picked from commit 1e611a33d5)
Currently targeting a device by serial requires matching the serial
number exactly. This CL relaxes the matching rules for local transports
to ignore protocol prefixes and make the port optional:
[tcp:|udp:]<hostname>[:port]
The purpose of this is to allow a user to set ANDROID_SERIAL to
something like "tcp:100.100.100.100" and have it work for both fastboot
and adb (assuming the device comes up at 100.100.100.100 in both
modes).
This CL also adds some unit tests for the modified functions to make
sure they work as expected.

(cherry picked from commit 71728ca300)
Currently adb only realizes a TCP transport has gone away when it tries
to send a packet, which caused problems in particular for `adb reboot`
since no packets are sent, leading to the client hanging until Ctrl+C.
This CL turns on TCP keepalive packets to send 1 packet every second,
allowing up to 10 failures before disconnecting. Using built-in TCP
functionality turns out to be much cleaner in this case than trying to
implement our own keepalive packets at the application layer, and
should be more lightweight since it's all done in the TCP stack.
