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
