Fix incorrect handling of module runtime and environment pointers.
We used to store module runtime and environment pointers in the static
lists Vmodule_runtimes and Vmodule_environments. However, this is
incorrect because these objects have to be kept per-thread. With this
naive approach, interleaving module function calls in separate threads
leads to environments being removed in the wrong order, which in turn
can cause local module values to be incorrectly garbage-collected.
Instead, turn Vmodule_runtimes and Vmodule_environments into
hashtables keyed by the thread objects. The fix is relatively
localized and should therefore be safe enough for the release branch.
Module assertions now have to walk the pointer list for the current
thread, which is more correct since they now only find environments
for the current thread.
Also add a unit test that exemplifies the problem. It interleaves two
module calls in two threads so that the first call ends while the
second one is still active. Without this change, this test triggers
an assertion failure.

naive approach, interleaving module function calls in separate threads
leads to environments being removed in the wrong order, which in turn
can cause local module values to be incorrectly garbage-collected.
The fix isn't completely trivial: specbinding the lists wouldn't work
either, because then the garbage collector wouldn't find the
environments in other threads than the current ones, again leading to
objects being garbage-collected incorrectly. While introducing custom
pseudovector types would fix this, it's simpler to put the runtime and
environment pointers into the specbinding list as new specbinding
kinds. This works since we need to unwind them anyway, and we only
ever treat the lists as a stack. The thread switching machinery
ensures that the specbinding lists are thread-local, and that all
elements of the specbinding lists in all threads are marked during
garbage collection.
Module assertions now have to walk the specbinding list for the
current thread, which is more correct since they now only find
environments for the current thread. As a result, we can now remove
the faulty Vmodule_runtimes and Vmodule_environments variables
entirely.
