implements the epm_Lookup() call, I'll add the other important calls
soon. I was rather pleased to find that epm_Lookup() worked first
time, which is particularly surprising given its complexity.
This required quite a bit of new infrastructure:
* a generic way of handling dcerpc policy handles in the rpc server
* added type checked varients of talloc. These are much less error
prone. I'd like to move to using these for nearly all uses of
talloc.
* added more dcerpc fault handling code, and translation from
NTSTATUS to a dcerpc fault code
* added data_blob_talloc_zero() for allocating an initially zero
blob
* added a endpoint enumeration hook in the dcerpc endpoint server
operations
