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. This
reduces the maximum VDI image size supported by QEMU to half of what it
currently is (down to approximately 512 TB).
The VDI test 084 has to be adapted accordingly. Actually, one could
clearly see that it was broken from the "Could not open
'TEST_DIR/t.IMGFMT': Invalid argument" line for an image which was
supposed to work just fine.

In preparation to possible automatic regression and performance
testing for the block layer I found that the iotests don't work
for all protocols anymore.
In commit 1f7bf7d0 I started to change supported protocols from
generic to file for various tests. Unfortunately, some tests
added in the meantime again carry generic protocol altough they
can only work with file because they require local file access.
The other way around for some tests that only support file I added
NFS protocol after confirming they work.

This updates the VDI corruption test to also test static VDI image
creation, as well as the default dynamic image creation.

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. Change to "1MB + 64KB" to match the 0x110000 value.
