* sysdeps/posix/getaddrinfo.c: Implement configuration file
handling. /etc/gai.conf can contain replacements for the label and precedence table. Fix byte order of default label and precedence table. * posix/gai.conf: New file. * posix/tst-rfc3484.c: Adjust for changes to getaddrinfo.c. * posix/tst-rfc3484-2.c: Likewise.

+# Configuration for getaddrinfo(3).
+#
+# So far only configuration for the destination address sorting is needed.
+# RFC 3484 governs the sorting. But the RFC also says that system
+# administrators should be able to overwrite the defaults. This can be
+# achieved here.
+#
+# All lines have an initial identifier specifying the option followed by
+# up to two values. Information specified in this file replaces the
+# default information. Complete absence of data of one kind causes the
+# appropriate default information to be used. The supported commands include:
+#
+# reload <yes|no>
+# If set to yes, each getaddrinfo(3) call will check whether this file
+# changed and if necessary reload. This option should not really be
+# used. There are possible runtime problems. The default is no.
+#
+# label <mask> <value>
+# Add another rule to the RFC 3484 label table. See section 2.1 in
+# RFC 3484. The default is:
+#
+#label ::1/128 0
+#label ::/0 1
+#label 2002::/16 2
+#label ::/96 3
+#label ::ffff:0:0/96 4
+#
+# precedence <mask> <value>
+# Add another rule the to RFC 3484 precendence table. See section 2.1
+# and 10.3 in RFC 3484. The default is:
+#
+#precendence ::1/128 50
+#precendence ::/0 40
+#precendence 2002::/16 30
+#precendence ::/96 20
+#precendence ::ffff:0:0/96 10
+#
+# For sites which prefer IPv4 connections change the last line to
+#
+#precendence ::ffff:0:0/96 100
