This makes clang-format useful on those. Also add a bunch of forgotten transitive includes, which otherwise prevented compilation.

// This is a system to schedule events into the emulated machine's future. Time is measured
|
|
// in main CPU clock cycles.
|
|
|
|
// To schedule an event, you first have to register its type. This is where you pass in the
|
|
// callback. You then schedule events using the type id you get back.
|
|
|
|
// See HW/SystemTimers.cpp for the main part of Dolphin's usage of this scheduler.
|
|
|
|
// The int cycles_late that the callbacks get is how many cycles late it was.
|
|
// So to schedule a new event on a regular basis:
|
|
// inside callback:
|
|
// ScheduleEvent(periodInCycles - cycles_late, callback, "whatever")
