pipe: make F_{GET,SET}PIPE_SZ deal with byte sizes
Instead of requiring an exact number of pages as the argument and return value, change the API to deal with number of bytes instead. This also relaxes the requirement that the passed in size must result in a power-of-2 page array size. Round up to the nearest power-of-2 automatically and return the resulting size of the pipe on success. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
