Title: Fix warning: 'va_start' has undefined behavior with reference types.

- fixing the clang-flagged varargs issue
* quick'n'dirty via boost preprocessor, long-term, we should
e.g. use boost program_options
(ceph_erasure_code already uses it anyway)
- interesting bug found: ceph_authtool.cc:84 called
ceph_argparse_flag with a std::string arg
- only converted one of the 6 varargs functions, pending
feedback
