Use the correct thread for memory accesses. (#459)
* Deal with vlenb being unreadable.
Instead of exiting during examine(), spit out a warning, and don't
expose the vector data registers. We do provide access to the vector
CSRs, because maybe they do work? It's just that we have no idea what
the size of the data registers is.

* Use the correct thread for memory accesses.
Previously, OpenOCD would perform RTOS memory accesses through the first
thread in the RTOS. This doesn't work if different threads have a
different memory view. For instance if `-rtos hwthread` is used, each
configured core could have address translation configured differently.
