Changed the way memory regions are referenced. Instead of a single
integer value, regions are now referred to by a region class and a region tag. The class specifies the type of region (one of CPU, gfx, sound, user, disk, prom, pld) while the tag uniquely specifies the region. This change required updating all the ROM region definitions in the project to specify the class/tag instead of region number. Updated the core memory_region_* functions to accept a class/tag pair. Added new memory_region_next() function to allow for iteration over all memory regions of a given class. Added new function memory_region_class_name() to return the name for a given CPU memory region class. Changed the auto-binding behavior of CPU regions. Previously, the first CPU would auto-bind to REGION_CPU1 (that is, any ROM references would automatically assume that they lived in the corresponding region). Now, each CPU automatically binds to the RGNCLASS_CPU region with the same tag as the CPU itself. This behavior required ensuring that all previous REGION_CPU* regions were changed to RGNCLASS_CPU with the same tag as the CPU. Introduced a new auto-binding mechanism for sound cores. This works similarly to the CPU binding. Each sound core that requires a memory region now auto-binds to the RGNCLASS_SOUND with the same tag as the sound core. In almost all cases, this allowed for the removal of the explicit region item in the sound configuration, which in turn allowed for many sound configurations to removed altogether. Updated the expression engine's memory reference behavior. A recent update expanded the scope of memory references to allow for referencing data in non-active CPU spaces, in memory regions, and in EEPROMs. However, this previous update required an index, which is no longer appropriate for regions and will become increasingly less appropriate for CPUs over time. Instead, a new syntax is supported, of the form: "[tag.][space]size@addr", where 'tag' is an optional tag for the CPU or memory region you wish to access, followed by a period as a separator; 'space' is the memory address space or region class you wish to access (p/d/i for program/data/I/O spaces; o for opcode space; r for direct RAM; c/u/g/s for CPU/user/gfx/sound regions; e for EEPROMs); and 'size' is the usual b/w/d/q for byte/word/dword/qword. Cleaned up ROM definition flags and removed some ugly hacks that had existed previously. Expanded to support up to 256 BIOSes. Updated ROM_COPY to support specifying class/tag for the source region. Updated the address map AM_REGION macro to support specifying a class/tag for the region. Updated debugger windows to display the CPU and region tags where appropriate. Updated -listxml to output region class and tag for each ROM entry.
