gethostbyname() is deprecated in favour of getaddrinfo()

[Mario Domenech Goulart]

The ​message by Moritz Wilhelmy is copied below:

While building the OpenSuSE package for Chicken, I discovered the following:

[  473s] RPMLINT report:
[  473s] ===============
[  482s] chicken-runtime.i586: I: binary-or-shlib-calls-gethostbyname 
/usr/lib/libchicken.so.7
[  482s] The binary calls gethostbyname(). Please port the code to use 
getaddrinfo().

 )

Do you think it would be a good idea to port chicken to use getaddrinfo()
instead, not that it's top priority or anything? getaddrinfo is part of
POSIX.1-2001 so it should be present on most systems, while POSIX.1-2008
removes gethostbyname() from the specification altogether.

At least, I hope this is easy (but probably quite a bit of work)
