Summary 08139: emumem: Memory leak after MAME hard reset
Description There's a big memory leak after doing a hard reset (Shift F3)
Steps To Reproduce - open Windows taskmanager to have a look at MAME's memory usage
- start a machine that allocates a lot of memory, for example:
mame.exe sun4_110 -window -ui_active

- look at memory usage and see it increase after each time you press Shift+F3
- eventually (after multiple GB total allocated), may get a crash:
Caught unhandled St9bad_alloc exception: std::bad_alloc

The crash is more likely to happen with a 32bit build.

Note, which machine/game you start, does not matter.
mame.exe pacman also leaks memory (much less since it doesn't allocate a lot), do Shift+F3 20 times and memory usage has doubled in pacman's case

The memory leak also happens if you restart the machine from MAME's internal UI, so:
mame.exe -> select sun4_110 -> exit back to UI -> select sun4_110 -> exit back to UI -> ...

 In my testing, regression points to the day of the great memory rewrite (emumem) from June 29, 2018:

 Does the leak happen with all machines, or only machines using specific features? Is something holding on to the memory, or is it losing hold of the memory entirely? I‘ve checked running simple systems with valgrind and they’ve come up clean.

 Suspicious-looking valgrind output from hard-resetting intlc440 a couple of times:

Looks like handlers aren’t being cleaned up properly.

So yeah, that's std::make_unique allocated memory, that's not supposed to be leakable unless the object with the unique_ptr objects is itself leaked. But I don't find it in the leak log, so I'm a little at a loss there. printf debugging, here we come...
