/*
 * Send an ICBM (instant message).  
 *
 *
 * Possible flags:
 *   AIM_IMFLAGS_AWAY  -- Marks the message as an autoresponse
 *   AIM_IMFLAGS_ACK   -- Requests that the server send an ack
 *                        when the message is received (of type 0x0004/0x000c)
 *   AIM_IMFLAGS_OFFLINE--If destination is offline, store it until they are
 *                        online (probably ICQ only).
 *   AIM_IMFLAGS_UNICODE--Instead of ASCII7, the passed message is
 *                        made up of UNICODE duples.  If you set
 *                        this, you'd better be damn sure you know
 *                        what you're doing.
 *   AIM_IMFLAGS_ISO_8859_1 -- The message contains the ASCII8 subset
 *                        known as ISO-8859-1.  
 *
 * Generally, you should use the lowest encoding possible to send
 * your message.  If you only use basic punctuation and the generic
 * Latin alphabet, use ASCII7 (no flags).  If you happen to use non-ASCII7
 * characters, but they are all clearly defined in ISO-8859-1, then 
 * use that.  Keep in mind that not all characters in the PC ASCII8
 * character set are defined in the ISO standard. For those cases (most
 * notably when the (r) symbol is used), you must use the full UNICODE
 * encoding for your message.  In UNICODE mode, _all_ characters must
 * occupy 16bits, including ones that are not special.  (Remember that
 * the first 128 UNICODE symbols are equivelent to ASCII7, however they
 * must be prefixed with a zero high order byte.)
 *
 * I strongly discourage the use of UNICODE mode, mainly because none
 * of the clients I use can parse those messages (and besides that,
 * wchars are difficult and non-portable to handle in most UNIX environments).
 * If you really need to include special characters, use the HTML UNICODE 
 * entities.  These are of the form ߪ where 2026 is the hex 
 * representation of the UNICODE index (in this case, UNICODE 
 * "Horizontal Ellipsis", or 133 in in ASCII8).
 *
 * Implementation note:  Since this is one of the most-used functions
 * in all of libfaim, it is written with performance in mind.  As such,
 * it is not as clear as it could be in respect to how this message is
 * supposed to be layed out. Most obviously, tlvlists should be used 
 * instead of writing out the bytes manually. 
 *
 * XXX more precise verification that we never send SNACs larger than 8192
 * XXX check SNAC size for multipart
