This reverts the changes in bug 1360308, bug 1390143 and bug 1469603. Minidump generation will now only happen on the main process' main thread which might lead to hangs but is known to be fairly robust. Asynchronous generation proved too brittle and enormously increased the complexity of this already hard-to-read code.
