Nir Soffer b7aa131519 qemu-io: Return non-zero exit code on failure
The result of openfile was not checked, leading to failure deep in the
actual command with confusing error message, and exiting with exit code 0.

Here is a simple example - trying to read with the wrong format:

    $ touch file
    $ qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $?
    can't open device file: Image is not in qcow2 format
    no file open, try 'help open'
    0

With this patch, we fail earlier with exit code 1:

    $ ./qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $?
    can't open device file: Image is not in qcow2 format
    1

Failing earlier, we don't log this error now:

    no file open, try 'help open'

But some tests expected it; the line was removed from the test output.

Kevin Wolf 9302e863aa parallels: Sanity check for s->tracks (CVE-2014-0142)
This avoids a possible division by zero.

Convert s->tracks to unsigned as well because it feels better than
surviving just because the results of calculations with s->tracks are
converted to unsigned anyway.

Kevin Wolf afbcc40bee parallels: Fix catalog size integer overflow (CVE-2014-0143)
The first test case would cause a huge memory allocation, leading to a
qemu abort; the second one to a too small malloc() for the catalog
(smaller than s->catalog_size), which causes a read-only out-of-bounds
array access and on big endian hosts an endianess conversion for an
undefined memory area.

The sample image used here is not an original Parallels image. It was
created using an hexeditor on the basis of the struct that qemu uses.
Good enough for trying to crash the driver, but not for ensuring
compatibility.
