[PATCH 12/13] mghttpd: Use gethostbyname instead of getaddrinfo.

[Christian Mauderer]

From: Christian Mauderer <Christian.Mauderer at embedded-brains.de>

RTEMS does not have a getaddrinfo() so use gethostbyname() instead. This
reintroduces a not thread save function into the code but it seems that
we have no better replacement at the moment.
