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

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 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.

Spotted this in mdssvc response that containied many results for a search
request: if the mdssvc response blob is larger then ~32k, the server fragments
the response in 32k fragments and sets the "fragment" field to 1.
Note that mdssvc implemenets result set "fragmentation" at the result set layer,
not at the marshalled response buffer layer. Therefor mdssvc always sets this
field to 0.

Add a new default backend that, while allowing mdsvc RPC and search queries from
clients, always returns no results.
Shares using this backend will behave the same way as shares on a macOS SMB
server where indexing is disabled.
This change will later also allow us to compile the Spotlight RPC service by
default which is a big step in the direction of adding tests to CI.

We need this in a later patchset when adding a mdssvc client library and for
unit tests.
