- support mdp clients over loopback UDP
Note this is using an environment variable to specify the port number
In future we expect to support environments where this port is already bound
- monitor mdp sockets in a single & separate thread
This allows the output fields of any command to contain nul characters, which
paves the way for extracting a manifest or other binary data directly instead
of having to write it into a temporary file.
Does not depend on ServalDResult class - appends output fields to a supplied
list instead, and returns the integer status
Does not depend on ServalDReentranceError class - uses
java.lang.IllegalStateException instead
