[Change description]
configure: generated with autoconf213
configure.in: added getaddrinfo and getnameinfo to AC_CHECK_FUNCS
config/autoconf.mk.in: added macros HAVE_GETADDRINFO and HAVE_GETNAMEINFO
ldap/clients/tools/common.c:
1. check if the given host name looks like IPv6 numeric address or not
2. if it is, try getaddrinfo + getnameinfo if available
3. if they are not or they failed, try NSPR functions, which are a bit old
handling IPv6 addresses, but for this case, they return the expected result --
FQDN.
