Expand description
Protobuf message types for the Mumble protocol, generated at build time from
the vendored .proto (see build.rs); never hand-transcribed (R1).
REF: references/vendored/Mumble.proto (package MumbleProto) — TCP control messages. REF: references/vendored/MumbleUDP.proto (package MumbleUDP) — UDP audio/ping envelope.
Note the UDPTunnel message defined in Mumble.proto is “Not used” on the wire:
a TCP frame of type UdpTunnel carries raw audio bytes, not this message. That
special case lives in the UDP envelope handling, not here.
