Callum Ryan 8539cb3f75 Allow the adb server to bind on ::1
Currently the adb server can only bind on 127.0.0.1 or * if -a is
provided. This diff adds the ability for adb to bind on ::1 as
well for use cases where you might want to force adb to be IPv6
only.

To bind the adb server on ::1
```
$ ./adb -L tcp:[::1]:1234 server
$ lsof -nPi :1234
COMMAND ... NODE NAME
adb     ...  TCP [::1]:1234 (LISTEN)
```
The original behaviour is also retained, so this would only affect
users explicitly specifying ::1 in the socket spec
```
$ export ANDROID_ADB_SERVER_PORT=1234
$ ./adb server
$ lsof -nPi :1234
COMMAND ... NODE NAME
adb     ...  TCP 127.0.0.1:1234 (LISTEN)
```

Note: I've only implemented this behaviour for posix base systems,
due to my limited understanding of networking on windows. If
needed I can do some research to implement it there as well, but
there is currently no IPv6 support at all on the windows side.

Test: New unit test and the commands in the summary
