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.

WIP: Support clone in userspace
...
Everything seems to work for the most part, but now there are tons of
daemons which rely on syscall::clone, which is now implemented in relibc
:(

Update to latest toolchain.
...
Multi-core is slightly broken when using the latest version of spin
(0.9.2). I believe this is because Once used to do SeqCst loads/stores
everywhere, which might have made any possible data race much harder to
come by.

Rewrite signal_handler_wrapper as single asm block.
...
The reason for these types of rewrites, is that more recent Rust
compilers have started to deprecate naked functions that consist of more
than only a single asm block, as they can trigger all sorts of UB.

Fix context switching.
...
Previously there was a triple fault, due to a combination of reasons
(e.g. rsp and rbp being ordered in the struct and in the assembly).
Now, the locks will be held __all the way until the new context__ has
been switched to, which completely eliminates any possibility that the
"pcid fault" originates here.
While I am unsure whether this will work, this could also be an
opportunity to be able to remove CONTEXT_SWITCH_LOCK fully.

WIP: Attempt to rewrite switch_to in assembly.
...
This is due to a warning in more recent compilers, which forbid anything
but a single inline assembly block, in naked functions. It does
unfortunately triple fault right now, but I hope I may be able to fix it
soon.
