Subject: Self test woes

Solar (and all),

I think we have to to adjust/add/do something with the self-tests for
certain formats.

My OpenCL RAR format runs for very long per crypt_all() call: One call
can take half a minute or much more (though I'm hoping to do better).
The upshot is that it may contain thousands of candidates, or hundreds
of thousands, or more.

But the self-tests just tries one hash, crypts, tries another one, calls
crypt, etc. which make the self-test take forever (since one hash takes
just as long to do as half a million of them). I had to comment out the
fmt_self_test(format) call from benchmark_format() (but left the
benchmark in place) just to be able to work on my format.

I do not have any particular proposition though. Any ideas? This format
is extreme but I think the problem is noticable with most other GPU
formats too. Just disabling self-test with a flag would be easy but
that's not a good solution - we need the tests. Maybe we could have a
flag that tells john to collate all tests into just one or two calls to
