Started working on the OpenSSH regression tests again. OpenBSD has a system-wide test suite and OpenSSH Portable imports the ssh tests. They're shell scripts (I think it was Larry Wall who said "it's easier to port a shell than a shell script") and they don't work on many of the platforms that -portable supports.

I have pulled in all the recent changes from OpenBSD so they're in sync at the moment. I also posted a largish patch that makes them work on many other platforms. If these portability changes are accepted back into OpenBSD's tests, then the same tests can be used for both. If not, -portable's tests will have to be a branch, much like the rest of OpenSSH.
