 Synopsis:
  This function breaks the string into a sequence of tokens. The difference
  between this function and strtok is that it respects the quoted string i.e.
  it skips  any delimiter character within the quoted part of the string. 
  It return tokens by eliminating quote character. It modifies the input string
  passed. It will work with whitespace delimeter but may not work properly with
  other delimeter. If the delimeter will contain any quote character, then
  function will not tokenize and will return null string.
  e.g. if input string is 
     --init-slave="set global max_connections=500" --skip-external-locking
  then the output will two string i.e.
     --init-slave=set global max_connections=500
     --skip-external-locking

Arguments:
  string:  input string
  delim:   set of delimiter character
Output:
  return the null terminated token of NULL.
