8fb8c40d3b fixed the rpc epmapper server. This fixes rpc over tcp.

7e6cf43756 This patch adds a better dcerpc server infastructure.
1.) We now register endpoint servers add startup via register_backend()
    and later use the smb.conf 'dcerpc endpoint servers' parameter to setup the dcesrv_context

2.) each endpoint server can register at context creation time as much interfaces as it wants
    (multiple interfaces on one endpoint are supported!)
    (NOTE:  there's a difference between 'endpoint server' and 'endpoint'!
	    for details look at rpc_server/dcesrv_server.h)

3.) one endpoint can have a security descriptor registered to it self
    this will be checked in the future when a client wants to connect
    to an smb pipe endpoint.

4.) we now have a 'remote' endpoint server, which works like the ntvfs_cifs module
    it takes this options in the [globals] section:

    dcerpc remote:interfaces = srvsvc, winreg, w32time, epmapper
    dcerpc remote:binding = ...
    dcerpc remote:user = ...
    dcerpc remote:password = ...

5.) we currently have tree endpoint servers: epmapper, rpcecho and remote

    the default for the 'dcerpc endpiont servers = epmapper, rpcecho'

    for testing you can also do
    dcerpc endpoint servers = rpcecho, remote, epmapper
    dcerpc remote:interfaces = srvsvc, samr, netlogon

6,) please notice the the epmapper now only returns NO_ENTRIES
    (but I think we'll find a solution for this too:-)

7.) also there're some other stuff left, but step by step :-)

This patch also includes updates for the
register_subsystem() , ntvfs_init(), and some other funtions
to check for duplicate subsystem registration

7efa19cd22 added a smb.conf flag "rpc big endian" that tells our rpc server to
send packets in bigendian format.

6f12e4ace1 it turns out that a wire policy handle isn't a blob either, its a
uint32 followed by a GUID. I needed to fix this to support running in
mixed-mode rpc (where smbtorture is bigendian and w2k3 is
little-endian). Otherwise when you send back a policy handle the
server doesn't recognise it.

24c22aef90 a fairly large commit!
This adds support for bigendian rpc in the client. I have installed
SUN pcnetlink locally and am using it to test the samba4 rpc
code. This allows us to easily find places where we have stuffed up
the types (such as 2 uint16 versus a uint32), as testing both
big-endian and little-endian easily shows which is correct. I have now
used this to fix several bugs like that in the samba4 IDL.

In order to make this work I also had to redefine a GUID as a true
structure, not a blob. From the pcnetlink wire it is clear that it is
indeed defined as a structure (the byte order changes). This required
changing lots of Samba code to use a GUID as a structure.

I also had to fix the if_version code in dcerpc syntax IDs, as it
turns out they are a single uint32 not two uint16s.

The big-endian support is a bit ugly at the moment, and breaks the
layering in some places. More work is needed, especially on the server
side.

f6eb8342cb added auto-generation of the server side boilerplate code for each
pipe.

The server side code gets generated as librpc/gen_ndr/ndr_NAME_s.c and
gets included in the pipe module

d009dc61f9 ntlmssp over rpc over tcp now fully works
I needed to hack the ntlmssp code a little, as the auth code in samba4
is out of date relative to the samba3 auth code. I need to do a merge :)

d262b8c3c7 completed the linkage between the endpoint mapper and the dcerpc
server endpoints. We can now successfully setup listening endpoints on
high ports, then use our endpoint mapper redirect incoming clients to
the right port.

also greatly cleanup the rpc over tcp session handling.

d4705378ce dcerpc over tcp in the samba4 server now works to some extent. It
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

8faa77f177 rpcdump.exe now works fine against a Samba4 server
for some reason the epm_Lookup replies can't be parsed by ethereal,
although w2k parses then fine as does the Samba4 NDR code.

340d9b71f9 added a basic dcerpc endpoint mapper to Samba4. Currently only
implements the epm_Lookup() call, I'll add the other important calls
soon. I was rather pleased to find that epm_Lookup() worked first
time, which is particularly surprising given its complexity.

This required quite a bit of new infrastructure:

  * a generic way of handling dcerpc policy handles in the rpc server

  * added type checked varients of talloc. These are much less error
    prone. I'd like to move to using these for nearly all uses of
    talloc.

  * added more dcerpc fault handling code, and translation from
    NTSTATUS to a dcerpc fault code

  * added data_blob_talloc_zero() for allocating an initially zero
    blob

  * added a endpoint enumeration hook in the dcerpc endpoint server
    operations

f7065cc0a5 after chatting with jeremy I decided to use a separate directory for
each rpc endpoint implementation, so we will have rpc_server/samr/
rpc_server/lsa/ etc.

this should encourage each pipe to be written in a more complete
manner, as it gives easy ways to split the pipe into multiple modules.

16309de71d * the RPC-ECHO pipe now works in smbd, as long as the data sizes
don't cause fragmented pdus (I'll add fragments shortly)

 * change data_blob_talloc() to not zero memory when the 2nd argument
   is NULL. The zeroing just masks bugs, and can't even allow a DOS
   attack

 * modified pidl to ensure that [ref] arguments to the out side of
   functions are allocated when parsing the in side. This allows rpc
   backends to assume that [ref] variables are all setup. Doesn't work
   correctly for [ref] arrays yet

 * changed DLIST_ADD_END() to take the type instead of a tmp
   variable. This means you don't need to declare a silly tmp variable in
   the caller
