edef 7e0b126f42 separate all the libc interaction out per OS 
We're now handling more of this ourselves, and leaving less to libstd.
Hopefully, we'll eventually break free of libstd, leaving a
highly-focused low-level library that retains all its conveniences in
freestanding environments.

edef 04bbeb88f4 add valgrind_stack_change 
Unlike valgrind_stack_register, this won't automatically swap
if `start > end`. It's probably wiser to pretend it doesn't swap at all.

edef db6a2ff89b factor Valgrind support out and expose it 
Now other Stack / StackSource implementations can use the same Valgrind
code. Ref #3.

edef c19fc4625a use a statically-allocated stack for Context::new benchmarking 
Now it's an actual context creation benchmark, instead of benchmarking
our stack creation, which is swappable anyway.

edef 31652d7b8f limit compilation of arch to x86_64 
the current code only supports x86_64 (#1), and we want to fail hard on
any other architecture for now.

edef 299a0a5d98 complete rewrite! 
featuring 7ns inlineable context switches, no more separately-built
assembly objects, and a vastly nicer interface.
incontext/outcontext are no more, context switch calls now take a single
context structure, which functions as both.
everything now also functions without any heap allocations -- for the
context setup, only an FnOnce() value is necessary.
