edef 976b971436 get rid of the old Context::swap
The two-parameter version is the only necessary API.

edef 3397e0bcf1 at least allow different lifetimes in Context::swap2
Really we should allow swapping between different stack types easily, so
we can easily swap between contexts with different stack types.

edef b986931817 remove copyright years
They're obnoxious to update, and I'm told they have no legal value.

edef 709dad1c4a add Context::swap2, to allow distinct save/restore contexts
Fix #5

Context::swap is now implemented in terms of Context::swap2, and it
might make sense to remove Context::swap entirely at some point.

edef cd4fe1ecc8 remove obsolete support for Rust stack limits
rustc removed these in 7a3fdfbf674a08b7f6fd32c9124e52924a2f9a1c, and
this removes a Linux-specific TLS slot from our code.

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

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

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)
```
