Move the struct adb definition from the auidioDB_API.h into the
audioDB-internals.h header file, leaving only the typedef behind.

Thus a user of the API sees only an incomplete type, which cannot be
instantiated (but /pointers/ to it can); there's then less temptation to
break the abstraction barrier by using structure fields in client code.

Not only that, but we can now safely put C++ stuff in the structure.
Take advantage of this by putting a std::set<std::string> in there, to
hold all the keys currently in the database; populate this field on
audiodb_open() (and delete it on audiodb_close).  This will be useful
when we come to implement variants of audiodb_insert().

# FIXME: this actually revealed a horrible failure mode of the server:
# since we were throwing exceptions from the constructor, the
# destructor wasn't getting called and so we were retaining 2Gb of
# address space, leading to immediate out of memory errors for the
# /second/ call.  We fix that by being a bit more careful about our
# exception handling and cleanup discipline, but how to test...?
