Support atoms subscription via shell cmd.
+ This feature is for supporting perfd.
+ Perfd is built outside android and doesnot depend on any android libraries.
So the communication between perfd and statsd can only be via non-android IPCs
(such as socket, pipe, file descriptors etc.)
+ Perfd runs as a shell user, so using the existing shell cmd is a natural choice.
+ The input is a simple config, and output is a stream of atoms proto binary data.
+ Also cleaned up the code so that we use file descriptor directly instead of creating another
FILE*.
