Subject[PATCH 1/6] dyndbg: recode for stronger precondition
Date
The table of struct _ddebugs, due to its construction by the linker,
has an important property; namely that its "equal" fields have actual
ptr-equality, not just strcmp-equality. Lets recognize that truth in
dynamic_debug_init(), while slicing the builtin table into a
per-module list.
