Adding Recursion Available bit to name_query and node_status_query

RFC 1002: 188.8.131.52:
RA 3 Recursion Available Flag.
Only valid in responses from a NetBIOS Name
Server -- must be zero in all other
..so Microsoft are getting it wrong. Not surprising, I suppose. The
RFCs are contradictory at times. In this case, 1002:4.2.15 says:
An end node responding to a NAME QUERY REQUEST always responds
with the AA and RA bits set for both the NEGATIVE and POSITIVE
NAME QUERY RESPONSE packets.
Which is obviously a contradiction. Dang them. I personally think that
the first should be the correct behavior as "Recursion Available" should
mean that the ability to go beyond the local name table, and talk to the
NBNS database, is available.
Just a question...are you sure you're checking RA and not RD? RD is also
set on almost everything.
