Forbid strong fdtbl refs after setting context's.
...
This fixes a possible file table leak if a filetable contains an fd
referring (strongly) to the filetable itself. Now, it will automatically
be downgraded to a weak reference after it becomes a context's active
file table.
TODO: maybe support consuming a context's filetable to get a strong
reference back, provided it's exclusively owned.
