This is a humongous commit, because it touches all parts of the
code. It removes the last user of our horrible TABLE macros, which
simulate std::vector<> in a very clumsy way.

Since the sorted_owning_table depends on the fact that
different elements never compare as equal, make the
comparison function safer in that respect. If all failes,
compare the pointers.

This is a long commit, because it introduces a new abstraction:
a general std::vector<> of std::unique_ptrs<>.
Moreover, it replaces a number of pointers by C++ references,
when the callee does not suppoert null objects.
This simplifies memory management and makes ownership more
explicit. It is a proof-of-concept and a test-bed for
the other core data structrures.
