waf build compilation errors

[Dimitris Gravanis]

Hi,

I've narrowed down most errors and fixed them.

I ran

$ waf configure --bundled-libraries=ALL
$ waf

in case my libraries were off, but it doesn't seem like that was the case.

There are still many warnings, but, having read the build logs, they're 
are probably not going to cause problems. I will however sent you the 
log when the errors I've prioritized are fixed

_My main issues are:_

*where are these types defined?
|DATA_BLOB: unknown type name||
||NTTIME: unknown type name|

*where are these function declared? (used in dns_server.c)
|tstream_read_pdu_blob_send()||
||tstream_read_pdu_blob_recv()|
I need to find their definitions to solve this errors in cli_dns.c

*In dns_server.c this is cast to NTSTATUS as well
|331: tstream_read_pdu_blob_recv: incompatible types to NTSTATUS (int)|

*In dns_server.c this is cast as a tevent_req
|348: tstream_read_pdu_blob_send: dereferencing pointer to incomplete 
type struct stream_connection|

*I also haven't found a declaration for packet_full_request_u16, which 
is a parameter to tstream_pdu_blob_send
|351: tstream_read_pdu_blob_send: packet_full_request_u16 undeclared|

dns_process_send/recv throw errors
|339: dns_process_send: dereferencing pointer to incomplete type struct 
task_server||
||365: dns_process_recv: incompatible types from int to WERROR

|I would also be good to make a mutual decision on the final submission 
format by tomorrow as well.

Cheers,
Dimitris
