For my taste this is a nicer configuration syntax than
/../username1/file1/../username2/file2/
Is this too expensive? I don't think so. The scanning only happens an
tcon time, and it only walks the parametric options. If this turns out
to be a performance problem, we should think about smarter data
structures for parametric options instead of just a linked list of
string triples for everything.

(cherry picked from commit 17becb5f52)
We'll have to add to an existing namearray soon.
This turns one talloc_array() into a set of reallocs. This is slower,
but set_namearray is only used for smb.conf entries where we don't
expect hundreds or more entries to add. I've done this to avoid array
length calculations, but if it turns out to be too slow we can get
smarter again.

We can't just free it, because has the GUID index list as a child, and
these are shared by the new dn list (from the subtransaction we are
committing). But if the dn list is long and the main transaction is
long-lived, we can save a lot of memory by turning this dn list into
an almost empty node in the talloc tree. This returns us to roughly
the situation we had prior to the last commit.
For example, with the repro.sh script on bug 15590 in indexes mode
with 10000 rules, The last 3 commits use this much memory at the end
of an unusually large transaction:
full talloc report on 'struct ldb_context' (total 4012222 bytes in 90058 blocks)
full talloc report on 'struct ldb_context' (total 2405482219 bytes in 90058 blocks)
full talloc report on 'struct ldb_context' (total 4282195 bytes in 90058 blocks)
That is, the last commit increased usage 500 fold, and this commit
brings it back to normal.

We don't want to modify the original list, but we can reuse the keys
if we treat them as immutable and don't free them. That makes it a lot
quicker if there are many keys (i.e. where an index is useful) and may
sub-transactions. In particular, it avoids O(n²) talloc_memdups.
A removed comment that says "We have to free the top level index
memory otherwise we would leak", and this will be addressed in the
next commit.

The strict flag is only read in list intersection, so most of the time
it doesn't matter whether it is set because that path is not used.
Nevertheless seeing it set to all kinds of values is distracting.
The undefined behaviour has likely been hidden from static analysis
because the structure is passed through the in-memory tdb before use.
Incorrect true values will have disabled an optimisation but not
caused the wrong result.

This will trace internal databases to files like this:

We avoid strlen(name) because name could be NULL in this case (which
works fine with glibc but feels bad).
