This first gets the clock_gettime_mono() value, converts to an NTTIME (as
this is what is stored in the dos attribute EA), then mixes in 8 bits of
randomness shifted up by 55 bits to cope with poor resolution clocks to
avoid duplicate inodes.
Using 8 bits of randomness on top of an NTTIME gives us around 114
years headroom. We can now guarentee returning a itime-based
fileid in a normal share (storing dos attributes in an EA).

fd_close() mostly wraps SMB_VFS_CLOSE() but also takes care of refcounting
fsp->fh properly and also makes sure that fsp->fh->fd is set to -1 after close.

With the removal of the call to flock LOCK_MAND, the only remaining use
of this VFS path is to register sharemodes with specific file systems.
Rename the VFS call to reflect that this is no longer related to flock.

This was needed before we had pathref fsps, with pathref fsps we can do
operation requiring WRITE_OWNER_ACCESS, WRITE_DAC_ACCESS and READ_CONTROL_ACCESS
on the pathref fsp.

This helps code inside any module implementing fstat() looking at
fsp->fsp_name->st instead of the passed in stat buf.
I only ran afoul of this in a DEBUG message I added while debugging some inode
related problem.
No change in behaviour.

Currently in master when we call into openat() in the VFS
we violate the invarient:
fsp->base_fsp->fsp_name->fsp == fsp->base_fsp.
The reason for this is subtle. Inside open.c:non_widelink_open()
we change the fsp->base_fsp to be relative to the new $cwd.
We do this by the following code in open.c:non_widelink_open():
/* Also setup base_fsp to be relative to the new cwd */
if (fsp->base_fsp != NULL) {
base_smb_fname_rel = (struct smb_filename) {
.base_name = smb_fname_rel->base_name,
};
orig_base_fsp_name = fsp->base_fsp->fsp_name;
fsp->base_fsp->fsp_name = &base_smb_fname_rel;
}
Note that fsp->base_fsp->fsp_name now points at a
stack variable struct smb_filename, with smb_fname->fsp == NULL.
This fixes that problem by removing the horrid
stack based smb_filename and changing to use a
talloc'ed fsp->base_fsp->fsp_name, with
correctly linked fsp->base_fsp->fsp_name-> pointer.
Remove the selftest/knownfail.d/fruit_vfs_invariant
file as all vfs_fruit tests now pass again.

Optimization now becomes clear. We already have a valid stat of the parent
directory so we don't need to re-do a system call.
