0798d54b4f r5195: most events don't need the time of the event, so save a gettimeofday() call
and just use timeval_current() when its actually needed

66170ef8b3 r5185: make all the events data structures private to events.c. This will
make it possible to add optimisations to the events code such as
keeping the next timed event in a sorted list, and using epoll for
file descriptor events.

I also removed the loop events code, as it wasn't being used anywhere,
and changed timed events to always be one-shot (as adding a new timed
event in the event handler is so easy to do if needed)

9b9c23b19b r5155: define ipv4address as a based IDL type, mapped to a "const char *" in
the header, and defined on the wire as a 4 byte network byte order
IP. This means the calling code doesn't have to worry about network
byte order conversions.

9a70f446fc r5126: the composite code is no longer client specific or smb specific, so
rename the core structure to composite_context and the wait routine to
composite_wait() (suggestion from metze)

0700676da6 r5120: encode outgoing nbt packets when queueing them rather than in the send
event code, as elements of the callers packet structure could go away
while the queue is pending (if for example a name was de-registered
while a packet referencing that name is queued)

5e6082b4b0 r5117: used a composite function to add 4 stage name registration. We send 3
broadcast name registration demands per name per interface at 1 second
intervals, then send a name overwrite request and demand. Any name
conflict replies are reported.

414f6c80b2 r5114: the nbtd task can now act as a basic B-node server. It registers its
names on the network and answers name queries. Lots of details are
still missing, but at least this now means you don't need a Samba3
nmbd to use Samba4.

missing pieces include:

 - name registrations should be "shout 3 times, then demand"

 - no WINS server yet

 - no master browser code

c7ded5ab0a r5108: the beginnings of a nbtd server for Samba4. Currently just displays
the packets it receives, but it at least shows how the server
structure will work.

To implement it I extended the libcli/nbt/ library to allow for an
incoming packet handler to be registered. That allows the nbt client
library to be used for low level processing of the nbtd server packets.

Other changes:

 - made the socket library always set SO_REUSEADDR when binding to an
   interface, to ensure that restarts of a server don't have to wait
   for a couple of minutes.

 - made the nbt port configurable. Defaults to 137, but other ports
   will be useful for testing.

6c14b0133d r4944: every event_add_*() caller was having to call talloc_steal() to take
control of the event, so instead build that into the function. If you
pass NULL as mem_ctx then it leaves it as a child of the events
structure.

fd62df6418 r4943: Smplified the events handling code a lot. The first source of
complexity was that events didn't automatically cleanup
themselves. This was because the events code was written before we had
talloc destructors, so you needed to call event_remove_XX() to clean
the event out of the event lists from every piece of code that used
events. I have now added automatic event destructors, which in turn
allowed me to simplify a lot of the calling code.

The 2nd source of complexity was caused by the ref_count, which was
needed to cope with event handlers destroying events while handling
them, which meant the linked lists became invalid, so the ref_count ws
used to mark events for later destruction.

The new system is much simpler. I now have a ev->destruction_count,
which is incremented in all event destructors. The event dispatch code
checks for changes to this and handles it.

6f0aef31cd r4898: - removed the unused wins_srv_*() code
- expanded the generic async name resolver to try multiple methods

- added wins resolutions to the list of methods tried

- fixed up the random trn id generation to use the good random generator

2383787f19 r4891: - added a generic resolve_name() async interface in libcli/resolve/,
which will eventually try all resolution methods setup in smb.conf

 - only resolution backend at the moment is bcast, which does a
   parallel broadcast to all configured network interfaces, and takes
   the first reply that comes in (this nicely demonstrates how to do
   parallel requests using the async APIs)

 - converted all the existing code to use the new resolve_name() api

 - removed all the old nmb code (yay!)

ea923fb4a2 r4885: added a new NBT client library. Features include:
- structures defined using IDL in nbt.idl
 - build around our events structure, and talloc
 - fully async
 - supports all NBT packet fields as per rfc1002
 - easy interfaces for name query and status

For the moment there are just a couple of test functions in
namequery.c, test_name_query() and test_name_status(). These will be
removed when we hook the new library into libcli/ fully

The new library will also be a fairly good basis for a nbt
server. Although it can't be a server as-is, I wrote it with the needs
of a server in mind (for example, extremely scalable idtree based
packet handling)
