Add an extra argument to "tvb_find_line_end()", which specifies what it

should do if it doesn't find an EOL; if FALSE, it behaves as before,
returning values that treat the line as ending at the end of the tvbuff,
and if TRUE, it returns -1, so its caller can do segment reassembly
until it gets the EOL.

Add an option to the SMTP dissector to do segment reassembly, and do
segment reassembly of the first line.
