I'm fine with making db_active ABI-stable, but why did you move it to
sys/systm.h?

We should tend toward exactly the opposite preference: fine-grained
purpose-limited header files like db_active.h, not giant incoherent
hodgepodges like systm.h touching any of which causes the entire
kernel to be rebuilt.

Can you please put ddb/db_active.h back?
