This avoids the need of using qemu_ram_alloc and mmap with MAP_FIXED to map a
host file into guest RAM. This function mmaps the opened file anywhere and adds
the memory to the ram blocks.
Usage is
qemu_ram_mmap(fd, size, MAP_SHARED, offset);
Signoff?
+ram_addr_t qemu_ram_mmap(int fd, ram_addr_t size, int flags, off_t offset)

Braces after if ()

More braces.
