-/*
- *  the qemud daemon program is only used within Android as a bridge
- *  between the emulator program and the emulated system. it really works as
- *  a simple stream multiplexer that works as follows:
- *
- *    - qemud is started by init following instructions in
- *      /system/etc/init.goldfish.rc (i.e. it is never started on real devices)
- *
- *    - qemud communicates with the emulator program through a single serial
- *      port, whose name is passed through a kernel boot parameter
- *      (e.g. android.qemud=ttyS1)
- *
- *    - qemud binds one unix local stream socket (/dev/socket/qemud, created
- *      by init through /system/etc/init.goldfish.rc).
- *
- *
- *      emulator <==serial==> qemud <---> /dev/socket/qemud <-+--> client1
- *                                                            |
- *                                                            +--> client2
- *
- *   - the special channel index 0 is used by the emulator and qemud only.
- *     other channel numbers correspond to clients. More specifically,
- *     connection are created like this:
- *
- *     * the client connects to /dev/socket/qemud
- *
- *     * the client sends the service name through the socket, as
- *            <service-name>
- *
- *     * qemud creates a "Client" object internally, assigns it an
- *       internal unique channel number > 0, then sends a connection
- *       initiation request to the emulator (i.e. through channel 0):
- *
- *           connect:<id>:<name>
- *
- *       where <name> is the service name, and <id> is a 2-hexchar
- *       number corresponding to the channel number.
- *
- *     * in case of success, the emulator responds through channel 0
- *       with:
- *
- *           ok:connect:<id>
- *
- *       after this, all messages between the client and the emulator
- *       are passed in pass-through mode.
- *
- *     * if the emulator refuses the service connection, it will
- *       send the following through channel 0:
- *
- *           ko:connect:<id>:reason-for-failure
- *
- *     * If the client closes the connection, qemud sends the following
- *       to the emulator:
- *
