This is the behaviour that most existing callers expect, but the
function actually returns a non-zero status code in that case.
Adjust all callers expecting the opposite behaviour to match.

If a talloc function returns NULL, indicating failure, the failure could
be masked by the next talloc call allocating on the NULL context.

If we don't check for NULL after each loop iteration, the failure could
be masked in the next iteration by talloc_asprintf_append() allocating
on the NULL context. That could result in values getting lost.

If we remove an element, we should not skip over the element following.

If we remove the i'th element, we should decrement i so that we don't
skip over the succeeding element.
If we remove the j'th element, we should decrement j and continue around
the loop, so as not to skip subsequent elements.

ldb_attr_in_list() already exists and does essentially the same thing.

Computing a pointer that points outside of an array, and not to one past
the last element, is undefined behaviour. To avoid this, do our
comparisons in terms of lengths, not pointers.

If the LDB_UNPACK_DATA_FLAG_NO_ATTRS flag is set, we don't return any
elements, so we should set num_elements accordingly. This ensures
callers don't try to access elements that aren't there.

Commit bed9efa6cd introduced
ldb_msg_add_linearized_dn() to replace ldb_msg_add_dn(), but retained
the now-incorrect associated comment. The comment later made its way
into a function added later by commit 'CVE-2022-32746 ldb: Add functions
for appending to an ldb_message'.

This comment originally referred, not to a va_copy() call, but to the
use of &c with vsnprintf() rather than passing in NULL with a length of
zero.

We used to store smbXsrv_tcon_global.tdb records in two steps,
first we created a record in order to allocate the tcon id.
The temporary record had a NULL share_name, which translated
into 0 bytes for the string during ndr_push_smbXsrv_tcon_global0.
The problem is that ndr_pull_smbXsrv_tcon_global0 fails on
this with something like:
Invalid record in smbXsrv_tcon_global.tdb:key '2CA0ED4A' ndr_pull_struct_blob(length=85) - Buffer Size Error
The blob looks like this:
[0000] 00 00 00 00 01 00 00 00 00 00 00 00 00 00 02 00 ........ ........
[0010] 00 00 00 00 4A ED A0 2C 4A ED A0 2C 00 00 00 00 ....J.., J..,....

[0050] 00 00 00 00 00 .....
The reason for having a temporary entry was just based on
the fact, that it was easier to keep the logic in
make_connection_snum() untouched.
But we have all information available in order to store
the final record directly. We only need to do the
"max connections" check first.
