limits on internal searches

[Pierangelo Masarati <ando@sys-net.it>]

I've run into a problem with test017 which is currently failing for HEAD
after I added some consistency checks on the values of search limits.
I'm about to fix it, but I found out that some syncrepl code is checking
search limits before running internal searches.  Is it intended?  I mean,
is there any reason the identity that performs an internal search needs to
check if any limits are set?  In that case, I strongly suggest any time 
limits
are checked, an appropriate value is provided to fields op->ors_tlimit
and op->ors_slimit.  By protocol, these fields can only have values >= 0,
so if theey're set to SLAP_NO_LIMIT (= -1) it means they're being used
in an internal search that requirs no limitations.  Otherwise, please set
them to 0 (no specific limit required, incurring in soft limits if any)
or to a positive value (e.g. 1 is used for auth{cz} related internal 
searches
because strictly one value is required.
