emumem: Simplify memory management. [O. Galibert]
API impact:
- install_ram/rom/writeonly now requires a non-null pointer. If you want
automatically managed ram, add it to a memory map, not in machine_start
- install_*_bank now requires a memory_bank *, not a string
- one can create memory banks outside of memory maps with memory_bank_creator
- one can create memory shares outside of memory maps with memory_share_creator
Memory maps impact:
- ram ranges with overlapping addresses are not shared anymore. Use .share()
- ram ranges touching each other are not merged anymore. Stay in your range
Extra note:
- there is no need to create a bank just to dynamically map some memory/rom.
Just use install_rom/ram/writeonly
