This change makes the MC146818/DS128x devices use the regular ASSERT_LINE/CLEAR_LINE protocol like almost all other devices, removing an unexpected surprise. The devices are fairly widely used, so I've tried to review all of those references and check if they're affected. A surprising number of systems appear to have the interrupt hooked up, but were not accounting for the inversion, so this change might possibly correct some behaviour.
The following were modified to remove workarounds:
* src/devices/machine/cs4031: removed inversion
* src/devices/machine/wd7600: removed inversion
* src/mame/drivers/apollo: hooked up interrupt
* src/mame/drivers/micronic: removed inversion
* src/mame/drivers/octopus: removed inversion
* src/mame/machine/apollo: removed timer workaround
* src/mame/machine/at: removed inversion
* src/mame/machine/interpro_ioga: removed inversion
The behaviour of the following might change:

* src/devices/bus/electron/cart/click.cpp
* src/devices/bus/lpci/southbridge.cpp

This makes these commands useful and consistent with dump in a virtual memory environment. One minor issue is what to do with save for an unmapped memory address: the approach taken here is to write the space.unmap() value, which seems the least harmful. On load, unmapped addresses are not written to, meaning that save/load with a constant address map work as expected.
