fsx: support 64-bit operation counts

Browse Source 
Support 64-bit operation counts so that we can run long-soak tests for
more than 2 billion fsxops.

I figured that testcalls and simulatedopcount should both be signed
because numops is also signed.  Granted, I guess numops is signed so
that we can set it to the magic value -1 and have fsx run "forever".

[Eryu: add Darrick's explanation about why we change testcalls to a
signed value.]
