Previously, each of the tests was spawning the fdevent thread manually, in order to be able to set up listeners and such before running fdevent_loop. Now that we have a way to run arbitrary code on the fdevent thread, switch to having a generic fdevent thread and running setup code via fdevent_run_on_main_thread. Test: adb_test Test: wine adb_test.exe Change-Id: I517dbcbad31067b45087d9fbed67a75b75a75aec
