Implement pvalloc replacement
...
Despite being an obsolete function, pvalloc is still present in GLIBC and should
work correctly when jemalloc replaces libc allocator.

Change assert_* to expect_* in tests
...
```
grep -Irl assert_ test/ | xargs sed -i \
's/witness_assert/witness_do_not_replace/g';
grep -Irl assert_ test/ | xargs sed -i \
's/malloc_mutex_assert_owner/malloc_mutex_do_not_replace_owner/g';
grep -Ir assert_ test/ | grep -o "[_a-zA-Z]*assert_[_a-zA-Z]*" | \
grep -v "^assert_"; # confirm no output
grep -Irl assert_ test/ | xargs sed -i 's/assert_/expect_/g';
grep -Irl witness_do_not_replace test/ | xargs sed -i \
's/witness_do_not_replace/witness_assert/g';

Hooks: Protect against reentrancy.
...
Previously, we made the user deal with this themselves, but that's not good
enough; if hooks may allocate, we should test the allocation pathways down
hooks. If we're doing that, we might as well actually implement the protection
for the user.

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

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
later.
