the old event context in the standard process modal child.

good, as it is probably a resource constraint, so if we just try again
we will spin (as the incoming socket will still be readable). Using a
sleep(1) solves this by throtting smbd until the resource constraint
goes away.
if the resource constraint doesn't go away, then at least smbd won't
be spinning chewing cpu

less likely that anyone will use pstring for new code
- got rid of winbind_client.h from includes.h. This one triggered a
huge change, as winbind_client.h was including system/filesys.h and
defining the old uint32 and uint16 types, as well as its own
pstring and fstring.

- removed the u32 hack in events.c as I think this was only needed as
tdb.h defines u32. Metze, can you check that this hack is indeed no
longer needed on your suse system?

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

- stream_socket services
the smb, ldap and rpc service which sets up a srtam socket end then
waits for connections
and
- task services
which this you can create a seperate task that do something
(this is also going through the process_model subsystem
so with -M standard a new process for this created
with -M thread a new thread ...
I'll add datagram services later when we whave support for datagram sockets in lib/socket/
see the next commit as an example for service_task's

- Re-disable tdbtool (it was building fine on my Debian box but other
machines were having problems)

deferred reply is short-circuited immediately when the file is
closed by another user, allowing it to be opened by the waiting user.
- added a sane set of timeval manipulation routines
- converted all the events code and code that uses it to use struct
timeval instead of time_t, which allows for microsecond resolution
instead of 1 second resolution. This was needed for doing the pvfs
deferred open code, and is why the patch is so big.

listening sockets after the fork to prevent the child still listening
on incoming requests.
I have also added an optimisation where we use dup()/close() to lower
the file descriptor number of the new socket to the lowest possible
after closing our listening sockets. This keeps the max fd num passed
to select() low, which makes a difference to the speed of select().

you set this option (either on the command line using --option or in
smb.conf) then every socket recv or send will return short by random
amounts. This allows you to test that the non-blocking socket logic in
your code works correctly.
I also removed the flags argument to socket_accept(), and instead made
the new socket inherit the flags of the old socket, which makes more
sense to me.

Rework our random number generation system.
On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork().
For other systems, we now only re-seed after a fork, and on startup.
No need to do it per-operation. This removes the 'need_reseed'
parameter from generate_random_buffer().
This also requires that we start the secrets subsystem, as that is
where the reseed value is stored, for systems without /dev/urandom.
In order to aviod identical streams in forked children, the random
state is re-initialised after the fork(), at the same point were we do
that to the tdbs.

the idea is to have services as modules (smb, dcerpc, swat, ...)
the process_model don't know about the service it self anymore.
TODO:
- the smbsrv should use the smbsrv_send function
- the service subsystem init should be done like for other modules
- we need to have a generic socket subsystem, which handle stream, datagram,
and virtuell other sockets( e.g. for the ntvfs_ipc module to connect to the dcerpc server
, or for smb or dcerpc or whatever to connect to a server wide auth service)
- and other fixes...
NOTE: process model pthread seems to be broken( but also before this patch!)

I also moved the substructs directly into smbsrv_connection,
because they don't need a struct name and we should allway pass the complete

I plan to convert all objectfile group to use SMB_SUBSYSTEM
later I'll add a SMB_BINARY() and SMB_LIBRARY(), then there will be no more need
to touch Makefile.in, because all make rules will be autogenerated by configure
- convert the PROCESS_MODEL subsystem to this new scheme
and move the pthread test to smbd/process_model.m4
- convert the CHARSET subsystem to this new scheme

high ports, then use our endpoint mapper redirect incoming clients to
the right port.
also greatly cleanup the rpc over tcp session handling.
