r21347: All current tests in the testsuite mainly test the RPC code in general. Since

we're running the testsuite mainly against ourselves, we only check that the
push/pull functions work in our own environment, not whether they generate/parse
the same data that other systems do.

This commit adds the infrastructure for a testsuite for just the marshalling
code. The idea is that you provide a data blob, a function name and a function
to check the resulting struct for correctness.
(This used to be commit 9bd2421e44dcfcaf08ad61cf25bb7714cf885517)
