Add support for an /etc/eui64 file modeled on /etc/ethers. The API is

modeled on ethers(3) except that all functions are thread-safe.

+.Sh NAME
+.Nm eui64
+.Nd IEEE EUI-64 address database
+.Sh DESCRIPTION
+The
+.Nm
+database contains information regarding known IEEE EUI-64s of hosts.
+The data is stored in a file called
+.Pa /etc/eui64
+in the following format:
+.Bd -unfilled -offset indent
+.Pa EUI-64 host-name
+.Ed
+.Pp
+Items are separated by any number of blanks and/or
+tab characters.
+A 
+.Dq #
+at the start of a line indicates the
+beginning of a comment that extends to the end of the line.
+Valid lines may also contain comments.
+A 
+.Dq +
+at the start of a line will cause the
+.Xr eui64 3
+library functions to use data stored in the
+.Xr NIS 4
+.Pa eui64.byname
+and
+.Pa eui64.byid
+maps in addition to the data in the
+.Pa /etc/eui64
+file.
+.Pp
+An EUI-64 is expressed in
+.Tn ASCII
+form as "x-x-x-x-x-x-x-x" where
+.Ar x
+is a hexadecimal value between 0x00 and 0xFF.
+The address values
+should be in network order.
+Hostnames specified in the
+.Pa /etc/eui64
+database should correspond to entries in the
+.Xr hosts 5
+file.
+./" .Pp
+./" The
+./" .Fn eui64_line
+./" function in the standard C library can be used to break individual
+./" lines in the
+./" .Pa /etc/eui64
+./" database into their individual components: a binary EUI-64 is
+./" stored as an
+./" .Pa eui64_addr
+./" structure, and a hostname stored as a character string.
