-------------------
Linux still doesn't actually implement IBT for userland. And by the pace
things are going, it will take another decade before it does. But OpenBSD
has it enabled *by default* already.
Drop the #ifdef __linux__. This should hurt other OSes when they finally
catch up with us.

-------------------
Initial IP-based caching implementation with O(logn) lookup.
Caching implemented via red-black trees, this can be improved and
further work is on-going to bring it closer to GNU's performance that
uses a LRU-MRU 8-entries based caching algorithm.
Prompted by robert@ who run into a runtime of an executed macro of
5 minutes in libreoffice. With this the execution is reduced to 58 seconds.

OK mortimer@, kettenis@.
--------------------
Make the unwind cache tread-safe by declaring it thread_local. Solves
segfaults seen on exception handling. ok kettenis@
