For a name that contains an illegal Windows character, the
directory listing code returns the mangled 8.3 name as the
primary name for the file.
If the original (non-mangled) filename cannot be converted
to UCS2 on the wire via iconv due to conversion error, we
should skip that name when returning a directory listing,
as we can't map back from a returned 8.3 name to a usable
non-mangled filename if the client sends it back to us.
As this is only done in a very slow path (name must be mangled)
or in the old DOS protocol listing code I don't feel too bad
about using a talloc/free pair here.

Right now we can only support one messaging_dgm_context per process
anyway, the code has checks for this. I would like to keep it that
way, in the future we will have multiple messaging_context's or
imessaging_context's filtering based upon the dst server_id.
Why this change? messaging_dgm's lockfile contains the
serverid->unique_id. When designing messaging_dgm, I had in mind to
remove the serverid.tdb and replace it with the dgm lockfiles for server
lookup and enumeration. I have a WIP-patchset that gets rid of almost
all users of serverid.tdb. The problem is serverid_exists. Here we don't
have a messaging_context available, and it would be pretty intrusive
to make it so. This problem has plagued us since ctdb was developed,
see for example the comment
/*
* This is a Samba3 hack/optimization. Routines like process_exists need to
* talk to ctdbd, and they don't get handed a messaging context.
*/
in messaging_ctdb.c. This patchset removes this problem in a radical way:
Treat the messaging_dgm context as one globally available structure and
be done with it. The ctdb socket could go the same way in the future.

To make this sane, also add an argv parameter and change the return

match what is needed by vfork_with_logging() and cast it when passing

struct db_namelist.

As we atomically create using O_CREAT|O_EXCL,
then if new_file_created is true, then
file_existed *MUST* have been false (even

We use the variable file_existed again in logic
below this statement, so we must set file_existed = false,
