Subject: [PATCH] Fix segfault in unused StSvtSeqAdjMaker (#576)

In some bfc.C tests, this maker may get instantiated but, Init() is
never called. Pointers not initialized to NULL in the constructor may
potentially be non-zero in the destructor, leading to needless seg
faults when quitting root4star.

Simple test: root4star -b -q -l 'bfc.C(-1)'
