// Write the line 'str' to the relevant log file such as
// '#channel.log' or 'nickname.log'.  'ircdstate->ircnick'
// is our own nick and is used to determine which log file
// to write to if the type is LOG_PRIVMSG.
// 'basedir' is the directory in which the 'logs' directory
// will be created in which logs are to be written.
//
// If LOG_PRIVMSG then it expects a string in the format:
// :from!bar@baz PRIVMSG to :hello world
//
// LOG_PRIVMSG is also used for NOTICEs.
//
// If LOG_JOINPART then it expects a string in the format:
// :nick!bar@baz JOIN :#channel
// or
// :nick!bar@baz PART #channel
//
// If LOG_TOPIC then it expects a string in the format:
// :nick!bar@baz TOPIC #channel :bla bla bla
//
// If LOG_NETWORK then it just logs the string verbatim in
// a file named 'ircdstate->ircdname'.log.
//
// If LOG_QUIT then it expects a string in the format:
// channelname :nick!bar@baz QUIT :bla bla bla
// 'channelname' probably has to be prepended manually by the
// caller since it doesn't feature in the raw message from
// the IRCd.  We need it in logline() to log to the relevant
// channel log file.  The caller probably has to call logline()
// multiple times for each channel the nick was in.
//
// If LOG_NICK then it expects a string in the format:
// channelname :oldnick!bar@baz NICK :newnick
// Same manual 'channelname' prepending as LOG_QUIT above.
//
// If LOG_MODE then it expects a string in the format:
// :nick!bar@baz MODE #channel foo bar [foo bar...]
//
// If LOG_KICK then it expects a string in the format:
// :kicker!bar@baz KICK #channel kickee :bla bla bla
//
// With the ":foo!bar@baz "prefix being important for all
// types.
//
// Returns the number of bytes written on success, or 0 on failure.
