A program might rely on functions implemented in vl.c, but implement its own main(). By placing main into a separate source file, there are no complaints about duplicate main()s when linking against vl.o. For example, the virtual-device fuzzer uses a main() provided by libfuzzer, and needs to perform some initialization before running the softmmu initialization. Now, main simply calls three vl.c functions which handle the guest initialization, main loop and cleanup.
