Need reviewer for 6891404: (fs) ACL tests fail with "Invalid argument" on ZFS (sol)

[Alan Bateman]

This one is Solaris specific and has been bugging Kelly as it causes a 
number of tests, that update ACLs, to fail. The bug is that we don't set 
the ACE_IDENTIFIER_GROUP flag on group@ entries (group@ is one of the 
special "who" fields defined by RFC 3530 for servers that support both 
ACLs and Unix permissions). The fix is trivial, and I've used the 
opportunity to change the code to check references rather than the 
principal name (as there is only one instance of each). The webrev is here:

Thanks,

Alan.
