That file should then appears like a raw disk image, and accesses to it result in accesses to the exported BDS. Right now, we only implement the necessary block export functions to set it up and shut it down. We do not implement any access functions, so accessing the mount point only results in errors. This will be addressed by a followup patch. We keep a hash table of exported mount points, because we want to be able to detect when users try to use a mount point twice. This is because we invoke stat() to check whether the given mount point is a regular file, but if that file is served by ourselves (because it is already used as a mount point), then this stat() would have to be served by ourselves, too, which is impossible to do while we (as the caller) are waiting for it to settle. Therefore, keep track of mount point paths to at least catch the most obvious instances of that problem.

Doing so allows converting to protocols that do not allow direct file creation, such as FUSE exports. The only problem is that for formats other than qcow2 and qed (qcow1 at least), this may lead to high disk usage for some reason, so we cannot do it everywhere. But we can do it in 028 and 089, so let us do that so they can run on FUSE exports. Also, in 028 this allows us to remove a 9-line comment that used to explain why we cannot safely filter drive-backup's image creation output.

and on everything but "file", $TEST_IMG_FILE is set. There are two ways we can fix this: First, we could make all tests adjust not only TEST_IMG, but also TEST_IMG_FILE if that is present (e.g. with something like _set_test_img_suffix $suffix that would affect not only TEST_IMG but also TEST_IMG_FILE, if necessary). This is a pretty clean solution, and this is maybe what we should have done from the start. But it would also require changes to most existing bash tests. So the alternative is this: Let _make_test_img see whether $TEST_IMG_FILE still points to the original value. If so, it is possible that the caller has adjusted $TEST_IMG but not $TEST_IMG_FILE. In such a case, we can (for most protocols) derive the corresponding $TEST_IMG_FILE value from $TEST_IMG value and thus work around what technically is the caller misbehaving. This second solution is less clean, but it is robust against people keeping their old habit of adjusting TEST_IMG only, and requires much less changes. So this patch implements it.

Note that this is no attempt at being definitely complete. There are some tests that might be modified to run on FUSE, but this patch still skips them. This patch only tries to pick the rather low-hanging fruits. Note that 221 and 250 only pass when .lseek is correctly implemented, which is only possible with a libfuse that is 3.8 or newer.
