Recently there have been a number of issues raised on Launchpad as a result of
fuzzing the am53c974 (ESP) device. I spent some time over the past couple of
days checking to see if anything had improved since my last patchset: from
what I can tell the issues are still present, but the cmdfifo related failures
now assert rather than corrupting memory.
This patchset applied to master passes my local tests using the qtest fuzz test
cases added by Alexander for the following Launchpad bugs:

I'm posting this now just before soft freeze since I see that some of the issues
have recently been allocated CVEs and so it could be argued that even though
they have existed for some time, it is worth fixing them for 6.0.

They are certainly something that we can fix for 6.0. However, please
include the testcases even if they are ugly, they can be cleaned up
later or (if never cleaned up) they still count as regression tests.
