FUJITA Tomonori 349a642565 rust: Add read_poll_timeout function ... Add read_poll_timeout function which polls periodically until a condition is met, an error occurs, or the timeout is reached. The C's read_poll_timeout (include/linux/iopoll.h) is a complicated macro and a simple wrapper for Rust doesn't work. So this implements the same functionality in Rust. The C version uses usleep_range() while the Rust version uses fsleep(), which uses the best sleep method so it works with spans that usleep_range() doesn't work nicely with. The sleep_before_read argument isn't supported since there is no user for now. It's rarely used in the C version.
