Revert software-installed slot/image options when changing software
- Remove emu.h's stealth include of emuopts.h through mconfig.h; reduce dependency on emuopts.h in other headers and source files.
- MCFG_CPU_FORCE_NO_DRC is now a CPU configuration parameter rather than a global one; it still works to override the -drc option setting.
