/*! \brief Event callbacks structure.
 *
 * All the communication with the IRC network is based on events. Generally
 * speaking, event is anything generated by someone else in the network,
 * or by the IRC server itself. "Someone sends you a message", "Someone
 * has joined the channel", "Someone has quits IRC" - all these messages
 * are events.
 *
 * Every event has its own event handler, which is called when the
 * appropriate event is received. You don't have to define all the event
 * handlers; define only the handlers for the events you need to intercept.
 *
 * Most event callbacks are the types of ::irc_event_callback_t. There are
 * also events, which generate ::irc_eventcode_callback_t,
 * ::irc_event_dcc_chat_t and ::irc_event_dcc_send_t callbacks.

 * \brief Views or changes the channel mode.
 *
 * \param session An initiated and connected session.
 * \param channel A channel name to invite to. Must not be NULL.
 * \param mode    A channel mode, described below. If NULL, the channel mode is
 *                not changed, just the old mode is returned.
 *
 * \return Return code 0 means success. Other value means error, the error
 *  code may be obtained through irc_errno(). Any error, generated by the
 *  IRC server, is available through irc_callbacks_t::event_numeric.
 *
 * The irc_cmd_channel_mode() is used to change or view the channel modes.
 * The \a channel mode is returned if the \a mode is NULL. If the \a mode
 * is not NULL, the mode for the \a channel will be changed. Note that,
 * only channel operators can change the channel modes.
 *
 * Channel mode is represended by the letters combination. Every letter has
 * its own meaning in channel modes. Most channel mode letters are boolean
 * (i.e. could only be set or reset), but a few channel mode letters accept a
 * parameter. All channel options are set by adding a plus sign before the
 * letter, and reset by adding a minus sign before the letter.
 *
 * Here is the list of 'standard' channel modes:
 *
 * - \a o \a nickname - gives (+o nick) or takes (-o nick) the channel
 *      operator privileges from  a \a nickname. This mode affects the
 *      users in channel, not the channel itself.
 *      Examples: "+o tim", "-o watson".
 *
 * - \a p - sets (+p) or resets (-p) private channel flag.
 *      Private channels are shown in channel list as 'Prv', without the topic.
 *
 * - \a s - sets (+p) or resets (-p) secret channel flag.
 *      Secret channels aren't shown in channel list at all.
 *
 * - \a i - sets (+i) or resets (-i) invite-only channel flag. When the flag
 *      is set, only the people who are invited by irc_cmd_invite(), can
 *      join this channel.
 *
 * - \a t - sets (+t) or resets (-t) topic settable by channel operator only
 *      flag. When the flag is set, only the channel operators can change the
 *      channel topic.
 *
 * - \a n - sets (+n) or resets (-n) the protection from the clients outside
 *      the channel. When the \a +n mode is set, only the clients, who are in
 *      channel, can send the messages to the channel.
 *
 * - \a m - sets (+m) or resets (-m) the moderation of the channel. When the
 *      moderation mode is set, only channel operators and the users who have
 *      the \a +v user mode can speak in the channel.
 *
 * - \a v \a nickname - gives (+v nick) or takes (-v nick) from user the
 *      ability to speak on a moderated channel.
 *      Examples: "+v tim", "-v watson".
 *
 * - \a l \a number - sets (+l 20) or removes (-l) the restriction of maximum
 *      users in channel. When the restriction is set, and there is a number
 *      of users in the channel, no one can join the channel anymore.
 *
 * - \a k \a key - sets (+k secret) or removes (-k) the password from the
 *      channel. When the restriction is set, any user joining the channel
 *      required to provide a channel key.
 *
 * - \a b \a mask - sets (+b *!*@*.mil) or removes (-b *!*@*.mil) the ban mask
 *      on a user to keep him out of channel. Note that to remove the ban you
 *      must specify the ban mask to remove, not just "-b".
 *

 * The color system of libircclient is designed to be easy to use, and

 * possible codes are:
 * - [B] ... [/B] - bold format mode. Everything between [B] and [/B] is written in \b bold.
 * - [I] ... [/I] - italic/reverse format mode. Everything between [I] and [/I] is written in \c italic, or reversed (however, because some clients are incapable of rendering italic text, most clients display this as normal text with the background and foreground colors swapped).
 * - [U] ... [/U] - underline format mode. Everything between [U] and [/U] is written underlined.
 * - [COLOR=RED] ... [/COLOR] - write the text using specified foreground color. The color is set by using the \c COLOR keyword, and equal sign followed by text color code (see below).
 * - [COLOR=RED/BLUE] ... [/COLOR] - write the text using specified foreground and background color. The color is set by using the \c COLOR keyword, an equal sign followed by text foreground color code, a dash and a text background color code.
 *
 * The supported text colors are:
 * - WHITE
 * - BLACK
 * - DARKBLUE
 * - DARKGREEN
 * - RED
 * - BROWN
 * - PURPLE
 * - OLIVE
 * - YELLOW
 * - GREEN
 * - TEAL
 * - CYAN
