r25543: Merge libreplace support for inet_pton, inet_ntop, getaddrinfo, getnameinfo

(and friends) from SAMBA_3_2, with some minor tweaks:

- avoid including network headers in replace.h unless absolutely required
- autoconf tests for getaddrinfo() in lib/replace

The heimdal-specific code also no longer looks for these functions anymore.
(This used to be commit b6d3fd84a5d7d814035e60d6fa22f19bed9f77da)
