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.
Bug: http://b/28347842
Change-Id: I6397261f4973d49f2f8e04257bf67b348585bb63
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

adb: search for a maximum of 16 emulators.
Change-Id: I51d01d4d1d8985c37c6cf3c4dbaa19eba49ae306
Android Wear has unfortunately been using port 5601 for years, which
falls into the range of ports we were previously polling for Android
emulators. Reduce the maximum number of emulators we can support so
that 5601 no longer falls within our range.

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.
