README is far from a complete, good and accurate document, but what's
in there should at least not have obvious errors.

We need to keep TDB_ALLOW_NESTING as default behavior,
so that existing code continues to work.

However we may change the default together with a major version
number change in future.

While studying tdb, I've noticed a couple of mismatches between readme
and actual code:

- tdb_open_ex changed it's log_fn argument to log_ctx
- there is now no tdb_update(), which it seems was transformed into
  non-exported tdb_update_hash()

There were other mismatches, but I don't remember them now, sorry.

ctdb wants a quick way to detect corrupt tdbs; particularly, tdbs with
loops in their hash chains.  tdb_check() provides this.

Using tdb_transaction_prepare_commit() gives us 2-phase commits. This
allows us to safely commit across multiple tdb databases at once, with
reasonable transaction semantics
