DatastoreAccess: add support for generic user-defined RPCs
I was lazy and in the NETCONF backend, the fillMap patch does not check
for actual string prefix match, it just optimistically trims the RPC
prefix. I think this is safe (definitely in the "won't crash" department
due to use of std::string::substr(), but also in the "won't produce
garbage" context because libyang is expected to validate everything).
In the sysrepo backend, I had to introduce some duplication into that
visitor which converts from our data types to sysrepo. It tirns out that
sysrepo::Session::set_item requires a separate S_Val, whereas in context
of handling an RPC's output, we have a Vals_Holder which, after
reallocation, becomes a Vals instance, and that one does not support
replacing the individual Val instances by "something" -- one has to call
a Val::set, and these methods are different from Val::Val constructors.
I'm explicitly testing for lists and containers because the
documentation looked a bit scary -- I understood it in a way which make
me spend extra effort to make sure that all that has to be created gets
created.
