Add a test for the backwards compatibility of generated files.

Browse Source 
It is not necessary to maintain full compatibility of generated files
for all of eternity, but this test will warn us if there is
a need to regenerate the files.

/* Attempts to test all the datatypes supported by ProtoBuf.
* This is a backwards-compatibility test, using bc_alltypes.pb.h.
* It is similar to test_encode3, but duplicated in order to allow
* test_encode3 to test any new features introduced later.
