nfs: build exportlist with multiple groupnodes
The EXPORT procedure of the MOUNT protocol does not correctly create structures for the 'groupnodes' in the reply. Each 'groupnode' should be a single entry in the 'nfs.rpc-auth-allow' volume option. Because the value is handled as a single string, the encoding of the groupnode->gr_name fails when the value of the volume option is longer than 255 characters. In the error case, encoding the EXPORTS reply fails, and the waiting 'showmount' command will not receive a reply and times out. Splitting the allowed entries and creating a groupnode for each one prevents the too long ->gr_name. This is following the structures for the EXPORTS reply in the MOUNT protocol more correctly as well. Note that the contents of ->gr_name is expected to be server dependent.

+#!/bin/bash
+#
+# The nfs.rpc-auth-allow volume option is used to generate the list of clients
+# that are displayed as able to mount the export. The "group" in the export
+# should be a list of all clients, identified by "name". In previous versions,
+# the "name" was the copied string from nfs.rpc-auth-allow. This is not
+# correct, as the volume option should be parsed and split into different
+# groups.
+#
+# When the single string is passed, this testcase fails when the
+# nfs.rpc-auth-allow volume option is longer than 256 characters. By splitting
+# the groups into their own structures, this testcase passes.
