    _______________________________________________________

Details:

struct sockaddr includes sa_len, but some systems like Linux doesn't have this
filed, which produces many compilation problems.
  - My solution was:
    - Create macros to write and read from sa_len/sin_len/sin6_len fields
    - Replace all occurrences this fields for the proper macro
    - Declare write macros as empty and read macros as default values on
systems where
      sa_len and pals are not supported
    - Use _HAVE_SA_LEN to identify whether the system supports sa_len
