```
std lib sleep APIs: add doc comments and no @intCast

The sleep APIs are now documented as having spurious wakeups and no
precision of timing guaranteed. They also cannot fail. This commit makes
the entire range of u64 legal values to pass to std.os.time.sleep and
std.os.time.posixSleep. Values that do not fit in the native system APIs
will cause a sleep for the longest possible duration and then be handled
as a spurious wakeup.
