Issues found while rolling own regression test suite

• https://github.com/mamedev/mame/issues/1069 -- can't emu.keypost() a line feed character
• https://github.com/mamedev/mame/issues/1193 -- emu.keypost() is confused by new generic_keyboard (PORT_CONDITION)
• https://github.com/mamedev/mame/issues/1329 -- emu.keypost() and PORT_TOGGLE do not mix
• emu.wait() does not block execution of coroutine, and runs faster that real time
• PORT_TOGGLE and Shift do not mix (affects ie15_kbd)
• controlling DIP switches from Lua is weird (affects ie15 and others)
• emu.keypost(A) crashes MAME
• can't emu.keypost() a mapped key? (F20 in dvk_ksm mapped to F12 is sent as F12)
• can't set RTC
