There are a couple of bugs in back-meta (HEAD, 2.2) plus one fixed in HEAD but
not backported to 2.2.

1) in meta_send_entry(), when calling dnNormalize() the __address__ of
op->o_tmpmmctx is erroneously passed instead of op->o_tmpmmctx itself (one of
the odds of using (void*) for cookies ;)

2) in meta_send_entry(), the attribute normalization routines are passed
op->o_tmpmemctx, while they should be passd NULL (as in back-ldap)

3) if a single target is used, the search ends with noSuchObject after returning
all the valid entries.

I've fixed this in HEAD and re22.
