block: vdi bounds check qemu-io tests This test checks for proper bounds checking of some VDI input headers. The following is checked: 1. Max image size (1024TB) with the appropriate Blocks In Image value (0x3fffffff) is detected as valid. 2. Image size exceeding max (1024TB) is seen as invalid 3. Valid image size but with Blocks In Image value that is too small fails 4. Blocks In Image size exceeding max (0x3fffffff) is seen as invalid 5. 64MB image, with 64 Blocks In Image, and 1MB Block Size is seen as valid 6. Block Size < 1MB not supported 7. Block Size > 1MB not supported [Max Reitz <mreitz@redhat.com> pointed out that "1MB + 1" in the test case is wrong.

With this patch, the output now claims 8EiB instead of -8388607T, which really is the correct rounding of largest file size supported by qemu (we could go 511 bytes larger if we used byte-accurate sizing instead of rounding up to the next sector boundary, but that wouldn't change the human-readable result).

block/vdi: Limit maximum size even futher The block layer read and write functions do not like requests which are bigger than INT_MAX bytes. Since the VDI bmap is read and written in a single operation, its size is therefore limited accordingly.
