    Fix builds with DJGPP
    
    CLA: trivial
    
    To get the master branch compiled with DJGPP some minor
    adjustments are required. They will have no impact on any other ports.
    The DJGPP port uses the Watt-32 library to provide the required network
    functionality and some of its headers need to be included.
    
    Neither DJGPP nor the Watt-32 library provide in_addr_t thus it must be
    provided as it is done for OPENSSL_SYS_WINDOWS in crypto/bio/b_addr.c.
    
    In the DJGPP section of include/internal/sockets.h the following Watt-32
    headers must be added:
    
      -  arpa/inet.h: to provide declaration of inet_ntoa required in crypto/bio/b_addr.c
      -  netinet/tcp.h: to provide defintion of TCP_NODELAY required in crypto/bio/b_sock2.c
