Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c

 Changes between 0.9.1c and 0.9.2

  *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c

     [Richard Levitte <levitte@stacken.kth.se>]

  *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()

     from `int' to `unsigned int' because it's a length and initialized by

     EVP_DigestFinal() which expects an `unsigned int *'.
