the mallctl, but not otherwise misbehave.

Hooks: move the "extra" pointer into the hook_t itself.
...
This simplifies the mallctl call to install a hook, which should only take a

Add "hook" module.
...
The hook module allows a low-reader-overhead way of finding hooks to invoke and
calling them.
For now, none of the allocation pathways are tied into the hooks; this will come
