a37d9a45d1 tevent: Fix callers of tevent_req_set_endtime
tevent_req_set_endtime internally already calls tevent_req_nomem and thus sets
the error status correctly.

74dbeba723 dnscli: Make a few functions static
We might want to use the tcp flavor in the future in the forwarder for a
single, persistent TCP connection. Then we can easily re-publish it.

623883083b libdns: dns/tcp client
Same signature as the UDP client in the same file. This opens and closes
the socket per request. In the future, we might want to create a
persistent TCP connection for our internal DNS server's forwarder. That
will require proper handling of in-flight requests. Something for
another day.

and merge it into libaddns private library for s3/s4 client use.

Also remove dependency in libcli/nbt, the code from libcli/dns subsystems
is not used there at all.

744f9910c8 libcli/dns: make 'clidns' private library out of DNS code in WAF build
After consolidating DNS resolver code to lib/addns, there is one piece
that still needs to be moved into a common DNS resolver library: DNS_HOSTS_FILE
subsystem. Unfortunately, direct move would require lib/addns to depend on
libcli/util/{ntstatus.h,werror.h} (provided by errors subsystem).

In addition, moving libcli/dns/* code to lib/addns/ would make conflicting
the dns_tkey_record struct. The conflict comes from source4/dns_server/ and is due
to use of IDL to define the struct. lib/addns/ library also provides its own definition
so we either need to keep them in sync (rewrite code in lib/addns/ a bit) or
depend on generated IDL headers.

Thus, making a private library and subsystem clidns is an intermediate step
that allows to buy some time fore refactoring.

c18954775e libcli/dns Improve dns_hosts_file, using Samba3's struct dns_rr_srv
By reworking the 'fake DNS' file to use struct dns_rr_srv it should be
possible to emulate that resolver layer as well as the Samba4
sockaddr_storage* based layer.  This will then give us a common DNS
emulation for 'make test'.
