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.

Fix UB in the locking code of context switching
...
The spin crate considers it UB to call force_write_unlock while there is
a threads trying to obtain a read lock on the same rwlock.
This also switches to the spinning_lot crate for the context rwlock as
it has support for a write guard keeping a reference to the rwlock using
an Arc instead of a reference.
