This fixes the following flaky test:
UNEXPECTED(failure): samba3.raw.oplock.batch26(nt4_dc)
REASON: Exception: Exception: (../../source4/torture/raw/oplock.c:3718): wrong value for break_info.count got 0x2 - should be 0x1
You can reproduce it with two small msleeps, which means it's a race
condition:

15a8af075a2 introduced a bug where we immediately wake up ourselves
after doing a watch_send, leading to two inter-smbd oplock break
messages for this case. In theory, this should not matter, as in the
oplock break handler in the destination smbd we check
(fsp->sent_oplock_break != NO_BREAK_SENT)
so that the break does not get sent twice. However, with the above two
sleeps the oplock holding client could send out its oplock downgrade
while the second inter-smbd break messages was on its way.
The real fix would be to note in the share mode array that the
inter-smbd message has already been sent, but as other users of
dbwrap_watched_watch_send might also be affected by this bug, this fix
should be sufficient to get rid of this flaky test.
Unfortunately, dbwrap_watch.c is now pretty complex and needs some
serious refactoring to become understandable again. But that's
something for another day, sorry.

Before 15a8af075a2 we did not have a separately allocated watchers
array and dbwrap_watched_save() could play (too) smart tricks with
dbwrap_record_storev(). Now that we always have watchers talloc'ed, we
can remove those smart tricks from dbwrap_watched_save() in the next
commit.

interested in whether a name is pointing to a real named stream most of the times.
