Z39.50 facet support. Facet specifications are passed for search in
other-information with ASN.1 as defined in facet.asn and OID
.10.1000.81.5 . Facets are expressed as an Attribute list as known
from Type-1/RPN queries.  Type 1 is field. Type 2 is sort order. Type
3 is limit (number of entries to get in response). yaz-ztest returns
dummy facets if a client asks for them.
