/**
 * Read a line from an inputstream into a byte buffer. A line might end with a LF or an CRLF. CR's are accepted inside a line and
 * are not understood as a beginning new line. This should work therefore on Mac OS X, Unix, Linux and Windows.
 * /*from   w w w  . j a v a 2  s. c o m*/
 * See http://en.wikipedia.org/wiki/Newline for more.
 *  
 * @param in the inputstream
 * @param maxSize the maximum amount of bytes to read until a CRLF or LF is reached, a value of zero or smaller disables a limit (use w/ care!)
 * @return the buffer where read bytes are appended, this buffer will not contain any CR's or or CRLF's at the end of the array. Null is
 * returned if EOF is reached.
 * @throws IOException if something is wrong w/ the stream or the maxSize is reached
