Use offset_of! in context::arch::switch_to.
...
This is definitely better than hardcoding the offsets!

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.

At present these are done 'wholesale' without any regard for x86_64.
That needs to change eventually.
