this means you can do:
talloc_set_destructor(ptr, my_destructor);
and your destructor will be called with the pointer as an argument
when the pointer is about to be freed. The destructor can refuse the
free by returning -1.
You can also increase the reference count on a pointer like this:
talloc_increase_ref_count(ptr);
and a talloc_free() will just reduce the reference count, only
actually freeing the memory when the count reaches zero.

it can only indicate programmer error, and doing a smb_panic() ensures
an automatic backtrace (and eventually an abort()).

This version does the following:
1) talloc_free(), talloc_realloc() and talloc_steal() lose their
(redundent) first arguments
2) you can use _any_ talloc pointer as a talloc context to allocate
more memory. This allows you to create complex data structures
where the top level structure is the logical parent of the next
level down, and those are the parents of the level below
that. Then destroy either the lot with a single talloc_free() or
destroy any sub-part with a talloc_free() of that part
3) you can name any pointer. Use talloc_named() which is just like
talloc() but takes the printf style name argument as well as the
parent context and the size.
The whole thing ends up being a very simple piece of code, although
some of the pointer walking gets hairy.
So far, I'm just using the new talloc() like the old one. The next
step is to actually take advantage of the new interface
properly. Expect some new commits soon that simplify some common
coding styles in samba4 by using the new talloc().

team meeting at CIFS04. It allows you to find the talloc context given
any pointer allocated with talloc.

talloc_free() O(1) in preparation. This also halves the number of
malloc() calls and increases our internal consistency checking,
without breaking valgrind testing.

implements the epm_Lookup() call, I'll add the other important calls
soon. I was rather pleased to find that epm_Lookup() worked first
time, which is particularly surprising given its complexity.
This required quite a bit of new infrastructure:
* a generic way of handling dcerpc policy handles in the rpc server
* added type checked varients of talloc. These are much less error
prone. I'd like to move to using these for nearly all uses of
talloc.
* added more dcerpc fault handling code, and translation from
NTSTATUS to a dcerpc fault code
* added data_blob_talloc_zero() for allocating an initially zero
blob
* added a endpoint enumeration hook in the dcerpc endpoint server
operations
