ea: QueryEaInfo support for index, restart, single

Browse source 
nfs41_open_state stores current ea index, and increments it for each successful entry returned.  index is set to 0 when the 'restart' argument is given.  cached directory listing is freed after the listing is complete

QueryEaInfo now sends up its output buffer size, and the daemon uses this to limit its results.  added checks for buffer overflows, which required changes to the downcall structure

updated driver error mappings for map_setea_error()
