Each header should only include the other headers it needs to compile; `devtools/reduce-includes.sh */*.h` does this. The C files then need additional includes if they don't compile. And remove the entirely useless wire/onion_wire.h, which only serves to include wire/onion_wiregen.h. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
