Using the standard macro makes it easier to move code into common, as
TALLOC_ZERO_P isn't standard talloc.

The SMB_MALLOC'ed rbt node data was not free'd on talloc free of
the db context. This is a quick fix using talloc instead of malloc
for allocation of the node data.
Since malloc was originally used for performance reasons, one
might want to reverse to malloc and create a talloc destructor
that walks the tree and frees all the node data if this talloc
approach proves to be too slow..

Only filled in for tdb so far, for rbt it's pointless, and ctdb itself needs to
be extended

In this low-level code, play tricks to reduce the number of allocations to the
possible minimum. I would not recommend this for higher-level code, but here it
pays off.

Thanks a lot. Fully correct. What about the attached little
simplification?

This is meant as a replacement for the internal tdb. To me it seems a bit silly
that for in-memory structures we do our own memory management. With this rbt
based approach we can make use of the system-supplied malloc.
