fix(sync/wait_condition): deadlock in WaitCondition::wait
...
Instead of using a simple switch to determine if preemption is enabled
(`is_preemptable: bool`), a counter is used instead. This handles the
case where a function holding a `PreemptGuard` calls another function
that creates a new `PreemptGuard`.

Replace all Arc::try_new with Arc::new
...
The global allocator panics when out of memory rather than returning an
errors. In addition there are plenty of other places where we don't
handle allocation failure anyway. At some point in the future we should
systematically handle out of memory conditions, but until then let's not
pretend we do and get rid of the usage of the unstable allocator_api
feature that is unlikely to get stabilized any time soon.

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.
