This will basically make the root directory a place for storing the
major telegraf interfaces, which will make telegraf's godoc looks quite
a bit nicer. And make it easier for contributors to lookup the few data
types that they actually care about.
closes#564
Also modifying the internal UDP listener/parser code to make it able to
handle higher load. The udp listener will no longer do any parsing or
string conversion. It will simply read UDP packets as bytes and put them
into a channel. The parser thread will now deal with splitting the UDP
metrics into separated strings.
This could probably be made even better by leaving everything as byte
arrays.
