Ass some unit tests to check if the minadbd service exit correctly in
the failure case. Also start the fuse and verify the socket communication
between minadbd with adb host, and minadbd with recovery.
Bug: 131037235

without dangling process.

This cl adds a socket pair to support the communication between recovery
and minadbd. Therefore, minadbd will be able to issue multiple commands
to recovery and get back the status of each command.
This cl also switches the adb sideload from the recovery menu to use
this protocol; and moves minadbd to a separate binary.
