We can double the speed of "adb sync" (on N9) if we increase SYNC_DATA_MAX
from 64KiB to 256KiB. This change doesn't do that, because I still haven't
managed to plumb through the information about whether we're a new adb/adbd
to file_sync_client.cpp and file_sync_service.cpp. But this is already a big
change with a lot of cleanup, so let's do the cleanup and worry about the
intended change another day...
This change does improve performance somewhat by halving the number of
lstat(2) calls made on the client side, and ensuring that most packets are
sent with a single write. This has the pleasing result of making the null
sync on an AOSP N9 go from just over 300ms to around 100ms, which means it
now seems instantaneous (https://en.wikipedia.org/wiki/Mental_chronometry).

This implements the logical opposite of 'adb forward', i.e.
the ability to reverse network connections from the device
to the host.
This feature is very useful for testing various programs
running on an Android device without root or poking at the
host's routing table.
Options and parameters are exactly the same as those for
'adb forward', except that the direction is reversed.
Examples:
adb reverse tcp:5000 tcp:6000
connections to localhost:5000 on the device will be
forwarded to localhost:6000 on the host.
adb reverse --no-rebind tcp:5000 tcp:6000
same as above, but fails if the socket is already
bound through a previous 'adb reverse tcp:5000 ...'
command.
adb reverse --list
list all active reversed connections for the target
device. Note: there is no command to list all
reversed connections for all devices at once.
adb reverse --remove tcp:5000
remove any reversed connection on the device from
localhost:5000
adb reverse --remove-all
remove all reversed connections form the current
device.
Reversed connections are tied to a transport, in other
words, they disappear as soon as a device is disconnected.
Simple testing protocol:
adb forward tcp:5000 tcp:6000
adb reverse tcp:6000 tcp:7000
nc -l localhost 7000
in another terminal:
echo "Hello" | nc localhost 5000
Will print "Hello" on the first terminal.

This adds a few new options/modes to 'adb forward':
adb forward --list
adb forward --remove <local>
adb forward --remove-all
adb forward --no-rebind <local> <remote>

Note that this only affects the host adb client and server programs,
i.e. it's compatible with devices running older adbd versions.

For manufacturing and testing, there is a need to talk to
whatever device is connected to a given port on the host. This
change modifies adb's "-s" option to take either a serial
number or a device path. The device paths of the connected
devices can be listed using "adb devices -l" whose output
will resemble:
List of devices attached
016B75D60A00600D usb:2-5 device
3031D0B2E71D00EC usb:1-4.3 device
The second column lists the device paths. If the -l option is
not given, the output from "adb devices" will be the same as
it used to be (i.e. the paths will not be printed).
The device path can also be obtained with the get-devpath
command:
$adb -s 3031D0B2E71D00EC get-devpath
usb:1-4.3
Note that the format of the device paths are platform dependent.
The example above is from Linux. On OS-X, the paths will be
"usb:" followed by hex digits. For other platforms, the device
paths will be printed as "????????????" and the -s option will
not be able to select a device until someone implements the
underlying functionality.
