r2709: finally solved the talloc reference problem.

The problem was that the simple "uint_t ref_count;" in a talloc chunk
did not give enough information. It told us that a pointer was
referenced more than once, but it didn't say who it was referenced
by. This means that when the pointer was freed we had no sane way to
clean up the reference.

I have now replaced ref_count with a "refs" list, which means that
references point to the pointer, and the pointer has a linked list of
references. So now we can cleanup from either direction without losing track of anything.

I've also added a LOCAL-TALLOC smbtorture test that tests talloc
behaviour for some common uses.

r2675: added a convenience function

  void *talloc_reference(const void *context, const void *ptr);

this function makes a secondary reference to ptr, and hangs it off the
given context. This greatly simplifies some of the current reference
counting code in the samr server and I suspect it will be widely used
in other places too.

the way you use it is like this:

domain_state->connect_state = talloc_reference(domain_state, connect_state);

that makes the element connect_state of domain_state a secondary
reference to connect_state. The connect_state structure will then only
be freed when both domain_state and the original connect_state go
away, allowing you to free them independently and in any order.

you could do this alrady using a talloc destructor, and that is what
the samr server did previously, but that meant this construct was
being reinvented in several places. So this convenience function sets
up the destructor for you, giving a much more convenient and less
error prone API.

This sort of bug happens quite easily with the new talloc_realloc()
interface. talloc_realloc() now looks like this:

  void *talloc_realloc(void *ptr, size_t size);

and if ptr is not NULL then everything is fine. If ptr is NULL then
talloc_realloc() presumes you want to allocate in the NULL context,
which is probably not what is wanted.

For now the solution is to initialise ptr like this:
  ptr = talloc(mem_ctx, 0);
so when the realloc happens it has a context to get hold of.

problem in a more robust manner

r2632: a new approach to handling const errors. We have had huge numbers of
const warnings for a long time, and no real way to approach a
solution. Some of them are unavoidable due to the way the C standard
works (for example, any function that provides strchr() like
functionality _must_ produce a const warning)

I will be converting a bunch of places that currently produce const
warnings to use the discard_const_p(). Some of these will be
unavoidable const problems, some of them will be ones we will fix up
over time. At least this change means we will no longer be swamped
with const warnings, and we will easily be able to see when new
problems emerge.
