The Event struct wraps a single *mut gpiod_edge_event pointer and is cast
from raw pointers in event_buffer.rs. Without #[repr(transparent)], the
layout compatibility is not guaranteed by the language specification.
Add #[repr(transparent)] to make the pointer cast sound, and replace
try_into().unwrap() with a simple 'as' cast for the sequence number
getters since c_ulong and usize are the same width on Linux.
