make(1): initialize global variables in dir.c
Calling CachedDir_Assign requires that the variable be initialized. On
most systems, NULL is represented as all-zero bits already. This change
is only for the few other systems.
Add some comments explaining the implementation of Dir_AddDir since that
is tricky to read from the code alone.
