fix crash in migration, 32-bit userspace on 64-bit host
This change fixes a long-standing immediate crash (memory corruption
and abort in glibc malloc code) in migration on 32bits.
The bug is present since this commit:

qemu-kvm: allocate correct size for dirty bitmap
The dirty bitmap copied out to userspace is stored in a long array,
and gets copied out to userspace accordingly. This patch accounts
for that correctly. Currently I'm seeing kvm crashing due to writing
beyond the end of the alloc'd dirty bitmap memory, because the buffer
has the wrong size.

@@ int kvm_get_dirty_pages_range(kvm_context_t kvm, unsigned long phys_addr,
- buf = qemu_malloc((slots[i].len / 4096 + 7) / 8 + 2);
+ buf = qemu_malloc(BITMAP_SIZE(slots[i].len));
r = kvm_get_map(kvm, KVM_GET_DIRTY_LOG, i, buf);
BITMAP_SIZE is now open-coded in that function, like this:
size = ALIGN(((mem->memory_size) >> TARGET_PAGE_BITS), HOST_LONG_BITS) / 8;
The problem is that HOST_LONG_BITS in 32bit userspace is 32
but it's 64 in 64bit kernel. So userspace aligns this to
32, and kernel to 64, but since no length is passed from
userspace to kernel on ioctl, kernel uses its size calculation
and copies 4 extra bytes to userspace, corrupting memory.
Here's how it looks like during migrate execution:
our=20, kern=24
our=4, kern=8
...
our=4, kern=8
our=4064, kern=4064
our=512, kern=512
our=4, kern=8
our=20, kern=24
our=4, kern=8
...
our=4, kern=8
our=4064, kern=4064
*** glibc detected *** ./x86_64-softmmu/qemu-system-x86_64: realloc(): invalid next size: 0x08f20528 ***
(our is userspace size above, kern is the size as calculated
by the kernel).
Fix this by always aligning to 64 in a hope that no platform will
have sizeof(long)>8 any time soon, and add a comment describing it
all. It's a small price to pay for bad kernel design.
Alternatively it's possible to fix that in the kernel by using
different size calculation depending on the current process.
But this becomes quite ugly.
Special thanks goes to Stefan Hajnoczi for spotting the fundamental
cause of the issue, and to Alexander Graf for his support in #qemu.

Improve accuracy of block migration bandwidth calculation
block_mig_state.total_time is currently the sum of the read request
latencies. This is not very accurate because block migration uses aio and
so several requests can be submitted at once. Bandwidth should be computed
with wall-clock time, not by adding the latencies. In this case,
"total_time" has a higher value than it should, and so the computed
bandwidth is lower than it is in reality. This means that migration can
take longer than it needs to.
However, we don't want to use pure wall-clock time here. We are computing
bandwidth in the asynchronous phase, where the migration repeatedly wakes
up and sends some aio requests. The computed bandwidth will be used for
synchronous transfer.

qemu-timer: Fix timers for w32
Commit
68c23e5520e8286d79d96ab47c0ea722ceb75041 removed the
multimedia timer, but this timer is needed for certain
Linux kernels. Otherwise Linux boot stops with this error:

So the multimedia timer is added again here.

qemu-img: allow rebase to a NULL backing file when unsafe
QEMU can drop a backing file so that an image file no longer depends on
the backing file, but this feature has not been exposed in qemu-img.
This is useful in an image streaming usecase or when an image file has
been fully allocated and no reads can hit the backing file anymore.
Since the dropping the backing file can make the image unusable, only
allow this when the unsafe flag has been set.

softfloat: fix floatx80 handling of NaN
The floatx80 format uses an explicit bit that should be taken into account
when converting to and from commonNaN format.
When converting to commonNaN, the explicit bit should be removed if it is
a 1, and a default NaN should be used if it is 0.
When converting from commonNan, the explicit bit should be added.
