/**
 * @brief Transaction command types used by Socket Frontend/IMEngine/Config, Helper and Panel.
 *
 * This commands are used in communication protocols of SocketFrontEnd, SocketIMEngine, SocketConfig, Helper and Panel.
 *
 * There are mainly four major protocols used in the communications among each part of SCIM:
 * - between SocketFrontEnd and SocketIMEngine (SocketFrontEnd is server)
 * - between SocketFrontEnd and SocketConfig (SocketFrontEnd is server)
 * - between Panel and FrontEnds (eg. X11 FrontEnd, Gtk IMModule and QT IMModule. Panel is server)
 * - between Panel and Helper (Panel is server).
 *
 * As soon as the socket to the server is established, the client must call function
 * scim_socket_open_connection() to create the connection and get the magic key for later communication.
 *
 * At the same time, the server must call function scim_socket_accept_connection() to
 * accept the connection and get the same magic key for later client verification.
 *
 * The valid types of servers are:
 * - "SocketFrontEnd"\n
 *   The socket FrontEnd server provides remote IMEngine and Config services.
 *   It accepts "SocketIMEngine" and "SocketConfig" clients.
 * - "Panel"\n
 *   The Panel server provides GUI and Helper management services.
 *   It accepts "FrontEnd" and "Helper" clients.
 *
 * The valid types of clients are:
 * - "SocketIMEngine"\n
 *   The socket IMEngine client acts as a proxy IMEngine forwarding all requests to SocketFrontEnd.
 *   It can only connect to "SocketFrontEnd" server.
 * - "SocketConfig"\n
 *   The socket Config client acts as a proxy Config forwarding all request  to SocketFrontEnd.
 *   It can only connect to "SocketFrontEnd" server.
 * - "FrontEnd"\n
 *   If a FrontEnd needs a Panel GUI services, it'll be a "FrontEnd" client of the Panel.
 *   It can only connect to "Panel" server.
 * - "Helper"\n
 *   All Helper objects should be "Helper" clients of a Panel.
 *   It can only connect to "Panel" server.
 *
 * Then the client and the server can communicate with each other via the socket by sending transactions.
 * 
 * Multiple commands and their data may be put into one transaction with a restricted order.
 * The data of a command must be put into the transaction just follow the command itself.
 *
 * A transaction sent from a socket client to a socket server (eg. SocketIMEngine to SocketFrontEnd)
 * must be started with a SCIM_TRANS_CMD_REQUEST command followed by an uint32 magic key of the client
 * (returned by scim_socket_open_connection() function.
 *
 * A transaction sent back to a socket client from a socket server must be started with a
 * SCIM_TRANS_CMD_REPLY command.
 *
 * So for example, the layout of a transaction sent from SocketIMEngine to SocketFrontEnd may look like:
 * - #SCIM_TRANS_CMD_REQUEST
 * - an uint32 data (the magic key of a client)
 * - #SCIM_TRANS_CMD_PROCESS_KEY_EVENT
 * - an uint32 data (the id of the IMEngineInstance object used to process the KeyEvent)
 * - a scim::KeyEvent data (the KeyEvent to be processed)
 *
 * Some commands may be used in more than one protocols for similar purpose, but they may have different
 * data in different protocol. 
 *
 * <b>Brief introduction of communication protocols used in SCIM:</b>
 *
 * Please refer to the descriptions of each Transaction commands for details.
 *
 * -# <b>Protocol used between SocketIMEngine and SocketFrontEnd</b>\n
 *   In this protocol, SocketFrontEnd is socket server, SocketIMEngine is client.
 *   - <b>from SocketIMEngine to SocketFrontEnd:</b>\n
 *     The Transaction sent from SocketIMEngine to SocketFrontEnd must
 *     start with #SCIM_TRANS_CMD_REQUEST and followed by an uint32 magic
 *     key which was returned by scim_socket_open_connection() and
 *     scim_socket_accept_connection().\n
 *     Before parsing the Transaction,
 *     SocketFrontEnd must verify if the magic key is matched.
 *     If the magic key is not matched, then SocketFrontEnd should just
 *     discard this transaction.\n
 *     There can be one or more commands and corresponding data right after the
 *     magic key.\n
 *     The valid commands which can be used here are:
 *     - #SCIM_TRANS_CMD_NEW_INSTANCE
 *     - #SCIM_TRANS_CMD_DELETE_INSTANCE

 *   - <b>from SocketFrontEnd to SocketIMEngine:</b>\n
 *     The Transaction sent back from SocketFrontEnd to SocketIMEngine must
 *     start with #SCIM_TRANS_CMD_REPLY and end with #SCIM_TRANS_CMD_OK or
 *     #SCIM_TRANS_CMD_FAIL to indicate if the request previously sent by
 *     SocketIMEngine was executed successfully.\n
 *     For some requests, like SCIM_TRANS_CMD_GET_FACTORY_LIST, etc.
 *     only some result data will be returned between #SCIM_TRANS_CMD_REPLY and #SCIM_TRANS_CMD_OK.\n
 *     For some requests, like SCIM_TRANS_CMD_PROCESS_KEY_EVENT, etc.

 *   - <b>from Helper to Panel:</b>\n
 *     The Transaction sent from Helper to Panel must
 *     start with #SCIM_TRANS_CMD_REQUEST and followed by an uint32 magic
 *     key which was returned by scim_socket_open_connection() and
 *     scim_socket_accept_connection().
 *     Before parsing the Transaction,
 *     Panel must verify if the magic key is matched.
 *     If the magic key is not matched, then Panel should just
 *     discard this transaction.\n
 *     There can be one or more commands and corresponding data right after the
 *     magic key.\n

 *     The Transaction sent from Panel to Helper must
 *     start with #SCIM_TRANS_CMD_REPLY and followed by an
