it. epoll is much more scalable than select(), but only exists on some
systems (such as Linux with the 2.6.x kernel). The code detects any
epoll system call failures at runtime and falls back to select() if
there is a problem, so it should be safe to compile this on a 2.6
kernel and run it on a 2.4.x kernel.
The speedup is quite large. It gains 20% in packet rate in the
BENCH-NBT test, on top of another 20% gain from the better timer
handling I added earlier. The really big gain will be when we are
dealing with large numbers of file descriptors. With epoll we can
handle hundreds of file descriptors all O(1), whereas with select it
is O(n).

events much more efficient (no linked lists need to be traversed, so
large numbers of timers are no problem)

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)

bind twice on each interface, once using the broadcast address and
once using the specific IP. We then only listen on the wildcard
address if we don't have "bind interface only" set. This also happens
to simplify the code that finds the right interface for an incoming
request.

event handler to trigger a free that could cause a timer to be
triggered twice. This changs fixes it properly by marking timer events
to be removed using a zero next_event time.
I also changed the default timeout for events.c to be infinite, so if
there are no events to handle then smbd will sit forever doing
nothing. That allows it to be swapped out completely when idle.

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

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.

themselves are run as a single process, but run as a child of the
main process when smbd is run in the standard model, and run as part
of the main process when in the single mode.
- rewrote the winbind template code to use the new task services. Also
fixed the packet queueing
- got rid of event_context_merge() as it is no longer needed

servers in smbd. The old code still contained a fairly bit of legacy
from the time when smbd was only handling SMB connection. The new code
gets rid of all of the smb_server specific code in smbd/, and creates
a much simpler infrastructures for new server code.
Major changes include:
- simplified the process model code a lot.
- got rid of the top level server and service structures
completely. The top level context is now the event_context. This
got rid of service.h and server.h completely (they were the most
confusing parts of the old code)
- added service_stream.[ch] for the helper functions that are
specific to stream type services (services that handle streams, and
use a logically separate process per connection)
- got rid of the builtin idle_handler code in the service logic, as
none of the servers were using it, and it can easily be handled by
a server in future by adding its own timed_event to the event
context.
- fixed some major memory leaks in the rpc server code.
- added registration of servers, rather than hard coding our list of
possible servers. This allows for servers as modules in the future.
- temporarily disabled the winbind code until I add the helper
functions for that type of server
- added error checking on service startup. If a configured server
fails to startup then smbd doesn't startup.
- cleaned up the command line handling in smbd, removing unused options
