Replace incorrect interrupt IA32-isms.

The code incorrectly documents and states that SS and RSP are
conditionally pushed, based on whether the privilege level changed. This
is correct on IA-32, but wrong on x86-64.

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.
