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:

15a8af075a 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 15a8af075a 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.

This makes debugging run-away processes much more efficient and even
possible at all: If the pool-usage output is more than 256MB, the
previous code could not realloc it and threw it away. Also, it is not
helpful for an already huge process to allocate even more.

Samba so far on a dbwrap_watch record either watches or stores a
record, but never both from the same db_record instance acquired from
a dbwrap_fetch_locked(). In one of the next commits this will change,
we will watch a record and at the same time store data into it. This
patch enables a watch_send() followed by a storev() by properly
keeping the watchers around.

The rounding is needed because when a file is created via eg an SMB2 CREATE
request, we need to calculate the correct File-ID for the QFID Create-Context or
for a subsequent GETINFO SMB request on the same file-handle.
Any later metadata request that received the File-ID will do so by going through
dos_mode() -> ... -> parse_dos_attribute_blob(), where the File-ID will be
calculated from the on-disk itime which has NTTIME resolution.
As long as that is the only available itime backend, I'm rounding itime inside
make_file_id_from_itime(), not in the callers.
