We found a few months ago that TDB_CLEAR_IF_FIRST is extremely
inefficient for large numbers of connections, due to a fundamental
limitation in the way posix byte range locking is implemented. Rather
than the nasty workaround we had for Samba3, we now have a single
"cleanup tmp files" function that runs when smbd starts. That deletes
the tmp tdbs, so TDB_CLEAR_IF_FIRST is not needed at all.

were also gensec bugs that didn't turn up until we hit error paths in
the krb5 code.

- converted the tid handling to use a idtree instead of bitmaps

caller doesn't have to worry about the constraint of only opening a
database a single time in a process. These wrappers will ensure that
only a single open is done, and will auto-close when the last instance
is gone.
When you are finished with a database pointer, use talloc_free() to
close it.
note that this code does not take account of the threads process
model, and does not yet take account of symlinks or hard links to tdb
files.

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!)

because this is the connection state per transport layer (tcp)
connection
I also moved the substructs directly into smbsrv_connection,
because they don't need a struct name and we should allway pass the complete
smbsrv_connection struct into functions

needs quite a bit more work to get it finished. The biggest missing
feature is the lack of NTLMSSP which is needed for basic
authentication over tcp

In general I prefer "struct foo" to just "foo" for most
structures. There are exceptions.
