Revert "Use "transient" files for blind writes, take 2".
This reverts commit fba105b1099f4f5fa7283bb17cba6fed2baa8d0c.
That approach had problems with the smgr-level state not tracking what
we really want to happen, and with the VFD-level state not tracking the
smgr-level state very well either. In consequence, it was still possible
to hold kernel file descriptors open for long-gone tables (as in recent
report from Tore Halset), and yet there were also cases of FDs being closed
undesirably soon. A replacement implementation will follow.
