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.

Switch from the memoffset crate to the offset_of feature
...
The memoffset crate requires const_refs_to_cell to work in const
contexts. This feature has some known issues around it's semantics. The
offset_of feature however is currently on track for stabilization.

Update to latest toolchain.

Multi-core is slightly broken when using the latest version of spin

everywhere, which might have made any possible data race much harder to
come by.

Fix possible race condition in paranoid ISRs.
...
Additionally, because it turned out to be infeasible to rely on
link-time constants in global_asm! code, I have also converted the
interrupt handlers to naked fns. This removes the proc-macro-reliant
"paste" dependency, but inserts a tiny ud2 at the end of every ISR.

This is the first step of integrating the log crate as the main way to

Also, reexport all log macros. This module should eventually be the
only logging API used in the kernel.
