Updates to naming library: - adds checking to ensure network and service tokens    do not contain child tokens that are not defined themselves   (watson@google.com) - make GetService and friends raise an exception if the service   requested isn't defined. This makes it more in line with what   GetNetAddr and friends does   (watson@google.com) - Decide whether a service is an alias or not based on whether it   is a properly formed PORT/PROTO pair (ie. it contains a slash).   Previous default assumed that malformed or misspelled services   were PORT/PROTO pairs regardless of content.   (sburford@google.com) - Accept hash in service comments (eg. "A = 10002/tcp # serial #2")   (sburford@google.com) - Change variable name "next" -> "next_item" since "next" is reserved.   (sburford@google.com)
