Normalize files containing unit test code:

Source files are split to place all unit test code into translation
units ending in .test.cpp with no other business logic in the same file,
and in directories named "test".

A new target is added to the SConstruct, invoked by:
    scons count
This prints the total number of source code lines occupied by unit tests,
in rippled specific code and excluding library subtrees.
