Log message:
- Add a flags argument to dohooks.
The flag can be either HOOK_REMOVE or HOOK_REMOVE|HOOK_FREE.
o HOOK_REMOVE removes the hook from the list before executing it.
o HOOK_FREE frees the hook after that.

- Let dostartuphooks use HOOK_REMOVE|HOOK_FREE so we can reclaim the memory.

- Let doshutdownhooks use HOOK_REMOVE so that when some shutdown hook
panics (they do that all the #_(_at_)_$%! time these days) we don't loop
for ever. Don't HOOK_FREE, it doesn't matter and I don't want to add
another possible panic condition for shutdown hooks.

- Actually free the pointer we're throwing away in hook_disestablish (I wonder
how much memory this has leaked over the years).
