03eeb36b74 virtio-devices: iommu: Search full range for GVA conversion 
Remove an erroneous optimisation that used the page size mask to reduce
the range to iterate through on the set of mappings. This doesn't work
as the virtio-iommu ranges are larger than a single page. This may have
worked in the past when the mappings were limited to a single page.

a1af4238ae virtio-devices: make ioeventfds() return an iterator 
MSHV's SEV-SNP implementation calls ioeventfds whenever there is an
event.

This change removes the need frequent allocation and deallocation of a
vector, while at the same time makes sure other call sites are
unaffected.

1f7b809619 block: increase the size of temporary vectors 
The size was set to one because without VIRTIO_BLK_F_SEG_MAX, the guest
only used one data descriptor per request.

The value 32 is empirically derived from booting a guest. This value
eliminates all SmallVec allocations observable by DHAT.

6fd5b0f696 fuzz: explicitly keep or reject fuzzer corpus 
When the main fuzzer function returns (), it is equivalent to
returning Corpus::Keep.

In some of the return paths, we want to reject the input so that the
libfuzzer won't spend more time mutating them.

The should make fuzzing more efficient. No functional change intended.
