r17956: LSA Cleanup!
This commit cleans up a number of aspects of the LSA interface.
Firstly, we do 2 simple searches on opening the LSA policy, to obtain
the basic information we need. This also avoids us searching for
dnsDomain (an invented attribute).
While I was at it, I added and tested new LSA calls, including the
enumTrustedDomainsEx call. I have also merged the identical structures
lsa_DomainInformation and lsa_DomainList.
Also in this commit: Fix netlogon use of uninitialised variables.
