romload cleanups:
- added running_machine to internal structure, removed as explicit parameter
- added new function rom_file_size() to compute the size of a ROM
- removed rom_first_chunk() and rom_next_chunk() which are no longer needed
- changed progress display to be based on size of ROMs loaded, not number
- changed temporary load buffer to be dynamically allocated
- fixed reload logic to handle skipped BIOSes
Also changed rand_memory() to use a fixed seed for consistent behavior.
