Functions to serialize / deserialize(restore) HBitmap. HBitmap should be saved to linear sequence of bits independently of endianness and bitmap array element (unsigned long) size. Therefore Little Endian is chosen. These functions are appropriate for dirty bitmap migration, restoring the bitmap in several steps is available. To save performance, every step writes only the last level of the bitmap. All other levels are restored by hbitmap_deserialize_finish() as a last step of restoring. So, HBitmap is inconsistent while restoring.

HBitmap is an implementation detail of block dirty bitmap that should be hidden from users. Introduce a BdrvDirtyBitmapIter to encapsulate the underlying HBitmapIter. A small difference in the interface is, before, an HBitmapIter is initialized in place, now the new BdrvDirtyBitmapIter must be dynamically allocated because the structure definition is in block/dirty-bitmap.c. Two current users are converted too.

In FIFO mode there are no parallel reads, hence there is no need to allocate separate buffers and clone the iovecs. The two cases of quorum_aio_cb are now even more different, and most of quorum_aio_finalize is only needed in one of them, so split them in separate functions.

There are some (mostly ISP-specific) name servers who will redirect non-existing domains to special hosts. In this case, we will get a different error message when trying to connect to such a host, which breaks test 162. 162 needed this specific error message so it can confirm that qemu was indeed trying to connect to the user-specified port. However, we can also confirm this by setting up a local NBD server on exactly that port; so we can fix the issue by doing just that.

iotest 093 contains a test that creates a throttling group with several drives and performs I/O in all of them. This patch adds a new test that creates a similar setup but only performs I/O in one of the drives at the same time. This is useful to test that the round robin algorithm is behaving properly in these scenarios, and is specifically written using the regression introduced in 27ccdd52 as an example.

In 27ccdd52 the throttling fields were moved from BlockDriverState to BlockBackend. However in a few cases the code started using throttling fields from the active BlockBackend instead of the round-robin token, making the algorithm behave incorrectly. This can cause starvation if there's a throttling group with several drives but only one of them has I/O.

Commit d2f39add "exec.c: Ensure right alignment also for file backed ram" added an additional alignment requirement on the size of backend file besides the previous page size. On x86, the alignment is changed from 4KB in QEMU 2.6 to 2MB in QEMU 2.7. This change breaks certain usages in QEMU 2.7 on x86, e.g. -object memory-backend-file,id=mem1,mem-path=/tmp/,size=$SZ -device pc-dimm,id=dimm1,memdev=mem1 where $SZ is multiple of 4KB but not 2MB (e.g. 1023M). QEMU 2.7 reports the following error message and aborts: qemu-system-x86_64: -device pc-dimm,memdev=mem1,id=nv1: backend memory size must be multiple of 0x200000 The same regression may also happen in other platforms as indicated by Igor Mammedov. This change is however necessary for s390 according to the commit message of d2f39add, so we workaround the regression by taking the change only on s390.

Since the hanlders are associated with a CharBackend, rather than the CharDriverState, it is more appropriate to store in CharBackend. This avoids the handler copy dance in qemu_chr_fe_set_handlers() then mux_chr_update_read_handler(), by storing the CharBackend pointer directly. Also a mux CharDriver should go through mux->backends[focused], since chr->be will stay NULL. Before that, it was possible to call chr->handler by mistake with surprising results, for ex through qemu_chr_be_can_write(), which would result in calling the last set handler front end, not the one with focus.

The qemu_chr_fe_claim_no_fail() for property are gone, since the property will raise an error instead. In other cases, where there is already an error path, an error is raised instead.
