'cancelling' status was introduced by commit 51cf4c1a, mainly to avoid a
possible start of a new migration process while the previous one still exists.
But we didn't expose this status to user, instead we returned the 'active' state.
Here, we expose it to the user (such as libvirt), 'cancelling' status only
occurs for a short window before the migration aborts, so for users,
if they cancel a migration process, it will observe 'cancelling' status
occasionally.
Testing revealed that with older libvirt (anything 1.2.13 or less) will
print an odd error message if the state is seen, but that the migration
is still properly cancelled. Newer libvirt will be patched to recognize
the new state without the odd error message.

Instead of passing icc_bridge from the PC initialization code to
cpu_x86_create(), make the PC initialization code attach the CPU to
icc_bridge.
The only difference here is that icc_bridge attachment will now be done
after x86_cpu_parse_featurestr() is called. But this shouldn't make any
difference, as property setters shouldn't depend on icc_bridge.

The code to check the bitmap for the allocation status of each sector
has been "disabled by reason" ever since the vpc driver existed.
The reason might be that we might end up reading sector by sector
in vpc_read if we really used it. This would be a performance desaster.
The current code would furthermore not work if the disabled parts get
reactivated since vpc_read and vpc_write only use get_sector_offset to
check the allocation status of the first sector of a read/write operation.
This might lead to sectors incorrectly treated as zero in vpc_read and
to sectors getting allocated twice in vpc_write.

The VHD spec [1] allows for total_sectors of 65535 x 16 x 255 (~127GB)
represented by a CHS geometry. If total_sectors is greater
than 65535 x 16 x 255 this geometry is set as a maximum.
Qemu, Hyper-V and disk2vhd use this special geometry as an indicator
to use the image current size from the footer as disk size.
This patch changes vpc_create to effectively calculate a CxHxS geometry
for the given image size if possible while rounding up if necessary.
If the image size is too big to be represented in CHS we set the maximum
and write the exact requested image size into the footer.
This partly reverts commit 258d2edb, but leaves support for >127G disks
intact.

The CHS calculation as done per the VHD spec imposes a maximum image
size of ~127 GB. Real VHD images exist that are larger than that.
Apparently there are two separate non-standard ways to achieve this:
You could use more heads than the spec does - this is the option that
qemu-img create chooses.
However, other images exist where the geometry is set to the maximum
(65535/16/255), but the actual image size is larger. Until now, such
images are truncated at 127 GB when opening them with qemu.
This patch changes the vpc driver to ignore geometry in this case and
only trust the size field in the header.
