Still chasing SLAP_NVALUES trashed filter bug

an unneccessary malloc.  (Actually, we should likely use local
filter structure to read things into and then malloc/copy once
we're sure there are no errors.)

and misc cleanup

so #ifdef for now.

but haven't yet figured out why NVALUES crashes in test003

also still need to clear mr's from the ad_map.)

#define h_errno (* __h_errno())
