322574834f vfs: remove dirfsp arg from SMB_VFS_CREATE_FILE()
This was supposed to be a shortcut to avoid passing dirfsp around as an explicit
function argument throughout the whole codebase when the new VFS design idea was
based on using *AT functions throughout the VFS.

Now that we've opted for basing the VFS on handles and *AT functions will only
be used in a much more limitted extent, it makes sense to remove this internal
dirfsp reference, otherwise the combination of internal fsp->dirfsp and
smb_fname->fsp is going to be a tough to wrap your head around.

b74653f2cd smbd: add twrp arg to synthetic_smb_fname()
Most places take twrp from a local struct smb_filename variable that the
function is working on. Some don't for various reasons:

o synthetic_smb_fname_split() is only called in very few places where we don't
  expect twrp paths

o implementations of SMB_VFS_GETWD(), SMB_VFS_FS_CAPABILITIES() and
  SMB_VFS_REALPATH() return the systems view of cwd and realpath without twrp info

o VFS modules implementing previous-versions support (vfs_ceph_snapshots,
  vfs_shadow_copy2, vfs_snapper) synthesize raw paths that are passed to VFS NEXT
  functions and therefor do not use twrp

o vfs_fruit: macOS doesn't support VSS

o vfs_recycle: in recycle_create_dir() we need a raw OS path to create a directory

o vfs_virusfilter: a few places where we need raw OS paths

o vfs_xattr_tdb: needs a raw OS path for SMB_VFS_NEXT_STAT()

o printing and rpc server: don't support VSS

o vfs_default_durable_reconnect: no Durable Handles on VSS handles, this might
  be enhances in the future. No idea if Windows supports this.

o get_real_filename_full_scan: hm.... FIXME??

o get_original_lcomp: working on a raw path

o msdfs: doesn't support VSS

o vfs_get_ntquota: synthesizes an smb_filename from ".", so doesn't support VSS
  even though VFS modules implement it

o fd_open: conn_rootdir_fname is a raw path

o msg_file_was_renamed: obvious

o open_np_file: pipes don't support VSS

o Python bindings: get's a raw path from the caller

o set_conn_connectpath: raw path

o set_conn_connectpath: raw path

c7a4578d06 s3: pass DCE RPC handle type to create_policy_hnd
Various RPC services expect policy handles of a specific type.

s3 RPC server did not allow to create policy handles with a specific
type while actually requiring that policy handle type itself in some
places.

Make sure we are able to specify the policy on-wire handle type when
creating the policy handle. The changes follow s4 DCE RPC server
implementation.

The original logic to always set on-wire handle type to 0 can be tracked
down to commit fdeea341ed when we didn't
really know about differences in on-wire handle types.

All but LSA trusted domain RPC calls do not check the on-wire handle
type in s3 RPC server.

Fixes trusted domain operations when Samba RPC client attempts to call
s3 RPC server to perform lsa_lsaRSetForestTrustInformation in FreeIPA.
This fix is a pre-requisite for FreeIPA-FreeIPA forest trust.

9bdf3ccde6 s3:rpc_server: Switch to core dcerpc server loop
This commit finally switches the RPC server implementation.

At the same we have to do other related changes to keep code compiling
and test environments running.

First avoid moving the session_info into the allocated pipes_struct memory
context as it is owned now by the core RPC server, and the s3compat pidl
compiler will update the pipes_struct session_info before dispatching
the call with dcesrv_call->auth_state->session_info.

Also, fix a segfault in the endpoint mapper daemon when it tries to delete
the endpoints previously registered over a NCALRPC connection.

If we have:

rpc_server : epmapper = external
rpc_server : lsarpc = external
rpc_daemon : epmd = fork
rpc_daemon : lsasd = fork

The sequence is:

* The endpoint mapper starts (start_epmd in source3/smbd/server.c)
* The lsarpc daemon starts (start_lsasd in source3/smbd/server.c)
  * The lsarpc daemon creates the sockets and registers its endpoints
    (rpc_ep_register in source3/rpc_server/lsasd.c)
  * The endpoint registration code opens a NCALRPC connection to the
    endpoint mapper daemon (ep_register in source3/librpc/rpc/dcerpc_ep.c)
    and keeps it open to re-register if the endpoint mapper daemon dies
    (rpc_ep_register_loop in source3/rpc_server/rpc_ep_register.c)
* When the endpoint mapper daemon accepts a NCALRPC connection it sets a
  termination function (srv_epmapper_delete_endpoints)
* Suppose the lsarpc daemon exits. The NCALRPC connection termination
  function is called.
* The termination function tries to delete all endpoints registered by that
  connection by calling _epm_Delete
* _epm_Delete calls is_privileged_pipe which access to
  pipes_struct->session_info.

As the call to _epm_Delete occurs outside of the PIDL generated code,
the pipes_stuct->session_info is NULL. This commit also sets
pipes_struct->session_info from the dcerpc_connection before calling
_epm_Delete. As the core rpc server supports security context multiplexing we
need to pass the dcesrv_connection to the termination function and let the
implementation pick a auth context. In the case of the endpoint mapper
the termination function has to pick one of type NCALRPC_AS_SYSTEM to
check if the connection is privileged and delete the endpoints
registered by the connection being closed.

Finally, the samba.tests.dcerpc.raw_protocol testsuite passes against
the ad_member environment.

eea1c425a6 s3:rpc_server: Register endpoint servers in external mdssd daemon
