We're going to add a call to share_entry_stale_pid(share_mode_entry) which takes
a non-const pointer (in order to eventually set e->state = true).

Until we actually start passing real dirfsps to fd_openat(), fd_openat()

As create_file_default() still need to be updated in the future to replace the
SMB_VFS_STAT() calls with AT-based versions, it asserts (dirfsp ==
dirfsp->conn->cwd_fsp).

These are the functions that *create* dirfsps, they can't *take* dirfsps as that

Both functions just take a pathname and the internal opening of the underlying

smbd and all previous-versions implementing VFS modules have been patched to
work with struct smb_filename.NTTIME twrp, so we can now safely strip @GMT
tokens from paths.
This also means that "@GMT-something/foo" and "foo" will both come out as "foo",
so we have to take care of the stat-cache now and change it to take and use an
additional twrp arg.
At the same time remove @GMT stripping from shadow_copy2. In theory this could
be made a seperate commit, but due to the absolute path and pstripped logic, it
felt too cumbersome to attempt this.
Leaving the exercize of removing the now unneeded stripped logic to a future
patchset.
