173e808ed4 s3: Remove share mode handling before we open the file
This is a significant behaviour change: We do not open the file under
the share mode lock anymore. This might lead to more open calls in case
of oplock breaks or sharing violations, but those are slow error paths
and as such might be not too performance sensitive. The benefit of this
patch is a significant reduction of complexity of open_file_ntcreate()

590d3138be s3: Fix fcb_or_dos_open after logic change
With the new behaviour, we call fcb_or_dos_open after open_file(). It
is open_file() that sets up the fsp so that fcb_or_dos_open can find it
in the list of fsps. Avoid finding the fsp we are just setting up.

8be0f4d30f s3: Copy share mode handling from before to after open_file
This is a 1:1 copy&paste of the oplock/sharemode code that we do before
an existing file is opened. It is a prerequiste for a patch that removes
all of that handling before we open the file.

c034ff7b15 s3: Slightly simplify is_stat_open
The "access_bits" clause is redundant. is_stat_open says that exactly
at least one of the stat_open_bits must be set and none else.

fe72740e82 loadparm: make the source3/ lp_ functions take an explicit TALLOC_CTX *.
They use talloc_tos() internally: hoist that up to the callers, some
of whom don't want to us talloc_tos().

A simple patch, but hits a lot of files.

6d903bf189 Cope with a (non-security) open race we've had for ever as NTCreateX isn't atomic on POSIX.
On open without create, the file did exist, but some
other (local or NFS) process either renamed/unlinked
and re-created the file with different dev/ino after
we walked the path, but before we did the open. We
could retry the open but it's a rare enough case it's
easier to just fail the open to prevent creating any
problems in the open file db having the wrong dev/ino
key.

3aa186f1d4 Simplify the logic in open_file() some more.
