Point out in the API that "backend" talloc_moves into the watched
database.

2f8055f676 dbwrap_watch: Remove the "prec" parameter from watch_recv
The initial idea was to have some "atomicity" in this API. Every
caller interested in a record would have to do something with
it once it changes. However, only one caller really used this
feature, and that is easily changed to not use it. So
remove the complexity.

54d0dbeae6 dbwrap: Add an alternative implementation of dbwrap_watch_record_send
The existing one with a separate dbwrap_watchers.tdb turns out to
create a performance penalty in a clustered environment. Non-clustered,
dbwrap_parse_record on non-existent records is very cheap, but in a
cluster environment this is very noticable.

This implementation puts the watcher information into the records itself. For
large records, this might be another performance penalty, because we have to
assemble the final record together with talloc and memcpy, but this might be
fixed later with a tdb_storev call.

d4ca284333 dbwrap: Add "blocker" to record_watch_send
Typicall, when we watch a record, we wait for a process to give up some
resource. Be it an oplock, a share mode or the g_lock. If everything goes well,
the blocker sends us a message. If the blocker dies hard, we want to also be
informed immediately.

cf0cb0add9 dbwrap: add a dbwrap_flags argument to db_open()
This is in preparation to support handing flags to backends,
in particular activating read only record support for ctdb
databases. For a start, this does nothing but adding the
parameter, and all databases use DBWRAP_FLAG_NONE.
