7b98319f30 s3: smbd: Remove MAX_OPEN_DIRECTORIES check in dptr_create().
This is a bug in that it's artificially limiting the number
of open directories an SMB2 client can have. If this code
was needed it should by SMB1 specific.

However we should allow the clients to decide for themselves
how many directory handles they need, not limit to MAX_OPEN_DIRECTORIES.

c9e996d78d s3: smbd: Fix delete-on-close after smb2_find
Both dptr_create() and can_delete_directory_fsp() are calling OpenDir_fsp()
to get a directory handle. This causes an issue when delete-on-close is
set after smb2_find because both directory handle instances share the same
underlying file descriptor. In addition the SMB_ASSERT() in destructor
smb_Dir_destructor() gets triggered.

To avoid this use OpenDir() instead of OpenDir_fsp().

Most of this is boilerplate, the only subtleties are in

vfs_catia.c
vfs_media_harmony.c
vfs_shadow_copy2.c
vfs_unityed_media.c

Where the path is modified then passed to SMB_VFS_NEXT_GET_NT_ACL().
In these cases the change uses synthetic_smb_fname() to
create a new struct smb_filename from the modified path.

1582006112 s3: smbd: have_file_open_below() fails to enumerate open files below an open directory handle.
There are three issues:

1). The memcmp checking that the open file path has the open
directory path as its parent compares using the wrong length
(it uses the full open file path which will never compare as
the same).

2). The files_below_forall() function doesn't fill in the
callback function or callback data when calling share_mode_forall(),
leading to a crash (which we never saw, as the previous issue (1)
meant the callback function would never be invoked).

3). When invoking the callback function from files_below_forall_fn()
we were passing in the wrong private_data pointer (needs to be
the one from the state, not the private_data passed into
files_below_forall_fn()).

Found when running the torture test smb2.rename.rename_dir_openfile

6d03aed15e s3: smbd: Fix a couple of tricky slow-path cases - don't return a mangled name for a name that cannot be converted.
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.
