o Reflect repo-copy of extattr.[c3] from libutil to libc, moving

  extattr namespace routines to the libc/posix1e directory.  While
  the extattr calls are not strictly POSIX.1e, POSIX.1e wasn't
  strictly ever approved, so I think that's OK.

-.Dt EXTATTR 3
-.Os
-.Sh NAME
-.Nm extattr_namespace_to_string ,
-.Nm extattr_string_to_namespace
-.Nd convert an extended attribute namespace identifier to a string and
-vice versa
-.Sh LIBRARY
-.Lb libutil
-.Sh SYNOPSIS
-.In sys/extattr.h
-.In libutil.h
-.Ft int
-.Fn extattr_namespace_to_string "int attrnamespace" "char **string"
-.Ft int
-.Fn extattr_string_to_namespace "const char *string" "int *attrnamespace"
-.Sh DESCRIPTION
-The
-.Fn extattr_namespace_to_string
-function converts a VFS extended attribute identifier to a human-readable
-string;
-the
-.Fn extattr_string_to_namespace
-function undoes the aforementioned operation,
-and converts a human-readable string representing a namespace to a
-namespace identifier.
-Although a filesystem may implement arbitrary namespaces,
-these functions only support the
-.Dv EXTATTR_NAMESPACE_USER
-.Pq Dq user
-and
-.Dv EXTATTR_NAMESPACE_SYSTEM
-.Pq Dq system
-namespaces,
-which are defined in
-.Xr extattr 9 .
-.Pp
-These functions are meant to be used in error reporting and other
-interactive tasks.
-For example,
-instead of printing the integer identifying an extended attribute in
-an error message,
-a program might use
-.Fn extattr_namespace_to_string
-to obtain a human-readable representation.
-Likewise,
-instead of requiring a user to enter the integer representing a namespace,
-an interactive program might ask for a name and use
-.Fn extattr_string_to_namespace
-to get the desired identifier.
-.Sh RETURN VALUES
-If any of the calls are unsuccessful, the value \-1 is returned
-and the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-.Bl -tag -width Er
-.It Bq Er EINVAL
-The requested namespace could not be identified.
-.El
-.Sh SEE ALSO
-.Xr extattr 2 ,
-.Xr getextattr 8 ,
-.Xr setextattr 8 ,
-.Xr extattr 9
-.Sh HISTORY
-Extended attribute support was developed as part of the
-.Tn TrustedBSD
-Project, and introduced in
-.Fx 5.0 .
-It was developed to support security extensions requiring additional labels
-to be associated with each file or directory.
