This PR cleans-up AbortSignal code duplication between fork/exec and spawn (which seem to share the same essential implementation). Removed
spawnWithSignal, and all logic is now inspawn.This PR does have two behaviour changes:
fork/execFile, where before forfork/execFilean abort caused an abort in next-tick, while now it'll callabortin the same tick (a pre-aborted signal still aborts in next-tick as before). The behaviour forspawnis unchanged.child.spawn()is called, so that ifchild.spawn()throws, the signal won't keep a reference to the "bad" child-process.
