Winbind can ask rpcd_lsad for LookupNames etc. This can recurse back
into winbind for getpwnam. We have the "_NO_WINBINDD" environment
variable set in winbind itself for this case, but this is lost on the
way into rpcd_lsad. Use a flag in global_sid_Samba_NPA_Flags to pass
this information to dcerpc_core, where it sets the variable on every
call if requested.

Arrays of SIDs are handled not fully consistently throughout the
codebase. Sometimes SIDs in the first and second positions represent a
user and a primary group respectively; other times they don't mean
anything in particular. Using these index constants in situations of the
former sort can help to clarify our intent.

This is important for the source3/rpc_server code as it might
be called embedded in smbd and may not run as root with access
to our private tdb/ldb files.
Note this is only really needed for 4.15 and older, as
we no longer run the rpc_server embedded in smbd,
but we better be consistent for now.
This should be able to fix the problem the printing no longer works
on Windows 7 with 2021-10 monthly rollup patch (KB5006743).
Windows uses NTLMSSP with privacy at the DCERPC layer on top
of NCACN_NP (smb).

This is used by the helpers of samba-dcerpcd: When accepting a DCERPC
client, normally the server engine would read the initial bind
packet. In case of samba-dcerpcd the bind packet will already be read
from the socket, so we need to inject it into the rpc server engine
externally.
