Improve LogicalCpu{Id,Set}, make set atomic.
...
Technically there should be an atomic and nonatomic set type, but perf
should be the same, as the nonatomic one would only be used when setting
the sched_affinity.

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.

WIP: Pin fmap grants that are borrowed too.
...
This might not be the most ideal solution, since a GiB grant can be
EBUSY blocked if a single page is used by an indefinitely-blocking
UserScheme. But, the alternatives would impose lots of additional
complexity, such as increasing the PageInfo size, adding more
refcounting arrays to grants, etc.
