preparation for adding code to pass the BASE-DENY1 and BASE-DENYDOS
tests, which require a shared filesystem handle for some specific
combinations of two DENY_DOS opens on the same connection.

database in the opendb lck, we ensure that the database is not closed
before the lock is gone. That ensures the lock destructor doesn't work
on a closed database.

The previous code didn't handle the case where the file got renamed or
deleted while waiting for the sharing violation delay. To handle this
we need to make the 2nd open a full open call, including the name
resolve call etc. Luckily this simplifies the logic.
I also expanded the RAW-MUX test to include the case where we do
open/open/open/close/close, with the 3rd open async, and that open
gets retried after both the first close and the 2nd close, with the
first retry failing and the 2nd retry working. The tests the "async
reply after a async reply" logic in pvfs_open().

deferred reply is short-circuited immediately when the file is
closed by another user, allowing it to be opened by the waiting user.
- added a sane set of timeval manipulation routines
- converted all the events code and code that uses it to use struct
timeval instead of time_t, which allows for microsecond resolution
instead of 1 second resolution. This was needed for doing the pvfs
deferred open code, and is why the patch is so big.

We found a few months ago that TDB_CLEAR_IF_FIRST is extremely
inefficient for large numbers of connections, due to a fundamental
limitation in the way posix byte range locking is implemented. Rather
than the nasty workaround we had for Samba3, we now have a single
"cleanup tmp files" function that runs when smbd starts. That deletes
the tmp tdbs, so TDB_CLEAR_IF_FIRST is not needed at all.

share_access support). This is enough for us to pass the BASE-DENY2
test, but is a long way from fully correct share modes.
