Replaced jbuild files with dune.

Please note that make test fails, but this is not caused by this PR (needs to be updated to use the latest interface from rpclib).

Good job.

Could you open a ticket about the unit test failure?

[lindig]

I see this in the Travis build. The build succeeds and this is the part of the test that fails:

 File "generator/test/storage_test.ml", line 70, characters 17-28:
- Error: Unbound module type Idl.RPCfunc
[ERROR] The compilation of xapi-storage failed at "/home/opam/.opam/4.07/bin/dune runtest -p xapi-storage -j 127".

[kc284]

Indeed; this module type and others were removed from the rpclib, but neither the README in rpclib was updated nor the tests here.

I don't understand why this has not lead to failures of xs-opam on Travis and I would expect failures if we merge. I think the tests should be disabled in the opam file for now to avoid this.

The job in xs-opam installs packages but does not seem to run tests. It might be a good idea to run them so as to catch cases like this.
