Move the notes on writing tests out of HACKING into a new file, and improve
them.

Many of the testing notes in the HACKING file were in duplicated in two places
in that file!  This change removes that duplication.  It also adds new sections
on “Where should I put a new test?” and “TestCase and its subclasses”, and
others like “Test feature dependencies” have been expanded.  The whole document
has generally been edited to be a bit more coherent.
