edef 3f0ec83bf3 remove valgrind_stack_change
This is a leftover from when we exposed these APIs to consumers, we
don't actually use this function.

edef ff25697444 remove StackSource
Nothing in this library took StackSources, and it's probably too
high-level a concept to include here. Maybe later.

It's fairly pointless to have submodules when there are only three
items.

edef cbc10fd311 cache page_size
page_size is used in every nearly every pointer calculation in os.rs,
and the Stack methods are called fairly often. It's definitely not worth
spilling registers for to call out to a libc function.
With this change, page_size becomes effectively free. It is cached in an
atomic usize, with relaxed ordering, so no actual atomic operations are
involved.

Benchmark:
```
test bench_page_size        ... bench:         5 ns/iter (+/- 1)
test bench_page_size_cached ... bench:         0 ns/iter (+/- 0)
```

edef 2760a0a7aa move Valgrind handling into Context
fix #3
This takes all Valgrind functionality private again.
Valgrind stack registrations are now associated with a Context, not with
a Stack. This makes sense, since it's only actually a stack when a
Context is running on it. Perhaps Valgrind will even be able to detect
early stack frees now.

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.
