Remove the sysbus_add_memory and sysbus_del_memory functions. These are trivial wrappers for mapping a memory region into the system memory space, and have no users now. Sysbus devices should never map their own memory regions anyway; the correct API for mapping an mmio region is for the creator of the device to use sysbus_mmio_map.

Don't map the pmem and dmem RAM memory regions in the milkymist-softusb device itself. Instead just expose them as sysbus mmio regions which the device creator can map appropriately. This allows us to drop the pmem_base and dmem_base properties. Instead of going via cpu_physical_memory_read/_write when the device wants to access the RAMs, we just keep a host pointer to the memory and use that.

bdrv_open_common() implements direct use of protocols by copying the pre-opened BlockDriverStates to bs using bdrv_swap(). It did however first set some fields in bs, which end up in file after the swap. When bdrv_open() destroys file, it appears to be open, and because it isn't, qemu could segfault while trying to close it. Reorder the operations to return immediately in such cases so that file is correctly detected as closed.

Instead of just checking once in exactly this order if there are dependendies, non-COW clusters and new allocation, this starts looping around these. This way we can, for example, gather non-COW clusters after new allocations as long as the host cluster offsets stay contiguous. Once handle_dependencies() is extended so that COW areas of in-flight allocations can be overwritten, this allows to continue with gathering other clusters (we wouldn't be able to do that without this change because we would have missed a possible second dependency in one of the next clusters). This means that in the typical sequential write case, we can combine the COW overwrite of one cluster with the allocation of the next cluster as soon as something like Delayed COW gets actually implemented. It is only by avoiding splitting requests this way that Delayed COW actually starts improving performance noticably.
