Lua API Channel.remove() and HTTPMessage.remove() expects 1 to 3
arguments (counting the manipulated object), with offset and length
being the 2nd and 3rd argument, respectively.
hlua_{channel,http_msg}_del_data() incorrectly gets the 3rd argument as
offset, and 4th (nonexistent) as length. hlua_http_msg_del_data() also
improperly checks arguments. This patch fixes argument handling in both.
Must be backported to 2.5.
