Subject: Stabilize basic timeout functionality

This commit renames and stabilizes:

* `Condvar::wait_timeout_ms` (renamed from `wait_timeout`)
* `thread::park_timeout_ms` (renamed from `park_timeout`)
* `thread::sleep_ms` (renamed from `sleep`)

In each case, the timeout is taken as a `u32` number of milliseconds,
rather than a `Duration`.

These functions are likely to be deprecated once a stable form of
`Duration` is available, but there is little cost to having these named
variants around, and it's crucial functionality for 1.0.
