API should use more defaults

[Peter Baumann]

currently, setting host, port, database is mandatory in the C++ and Java API. This should provide the well-known defaults to simplify application programming. This should be all needed for localhost:

database.open();

…and we even could make this fully automatic allowing to avoid database open (and, similarly, for transactions where we transparently could allocate one by default).

There's also user credentials that need to be set before the open().

I'd close this ticket as wontfix, using the C++ and Java API is so rare that these type of improvements are not really worth doing. It will not help in a client like rasql, because it anyway needs to work with the default values.
