  block migration: fix return value

Modify block_save_iterate() to return positive/zero/negative
(success/not done/failure) return status. The computation of
the blocks transferred (an int64_t) exceeds the size of an
int return value.

  vmdk: Fix error for JSON descriptor file names

If vmdk blindly tries to use path_combine() using bs->file->filename as
the base file name, this will result in a bad error message for JSON
file names when calling bdrv_open(). It is better to only try
bs->file->exact_filename; if that is empty, bs->file->filename will be
useless for path_combine() and an error should be emitted (containing
bs->file->filename because desc_file_path (which is
bs->file->exact_filename) is empty).

Add a test for vmdk files which use a file with a JSON file name, and
which then try to open extents. That should fail and the error message
should at least try to look helpful.

  block: vhdx - update PAYLOAD_BLOCK_UNMAPPED value to match 1.00 spec

The 0.95 VHDX spec defined PAYLOAD_BLOCK_UNMAPPED to be 5.  The 1.00
VHDX spec redefines PAYLOAD_BLOCK_UNMAPPED to be 3 instead.

The original value of 5 is now an undefined state in the spec, but it
should be safe to treat it the same and return zeros for data read.
This way, we can maintain compatibility with any images out in the wild
that may have been created in accordance to the 0.95 spec.

  Log Message:
  -----------
  block: vhdx - change .vhdx_create default block state to ZERO

The VHDX spec specifies that the default new block state is
PAYLOAD_BLOCK_NOT_PRESENT for a dynamic VHDX image, and
PAYLOAD_BLOCK_FULLY_PRESENT for a fixed VHDX image.

However, in order to create space-efficient VHDX images with qemu-img
convert, it is desirable to be able to set has_zero_init to true for
VHDX.

There is currently an option when creating VHDX images, to use block
state ZERO for new blocks.  However, this currently defaults to 'off'.
In order to be able to eventually set has_zero_init to true for VHDX,
this needs to default to 'on'.

This patch changes the default to 'on', and provides some help
information to warn against setting it to 'off' when using qemu-img
convert.

[Max Reitz pointed out that a full stop was missing at the end of the
VHDX_BLOCK_OPT_ZERO option help text.  I have added it.

  qemu-io: Add sigraise command

abort() has the sometimes undesirable side-effect of generating a core
dump. If that is not needed, SIGKILL has the same effect of abruptly
crash qemu; without a core dump.

Thus, -c abort is not always useful to simulate a qemu-io crash;
therefore, this patch adds a new sigraise command which allows raising
a signal.

Test 039 used qemu-io -c abort for simulating a qemu crash; however,
abort() generally results in a core dump and ulimit -c 0 is no reliable
way of preventing that. Use "sigraise $(kill -l KILL)" instead to have
it crash without a core dump.

After the previous patch, laio_submit already tried to avoid submitting
