This is a major rewrite of the RISC-V v0.13 OpenOCD port. This
shouldn't have any meaningful effect on the v0.11 support, but it does
add generic versions of many functions that will allow me to later
refactor the v0.11 support so it's easier to maintain both ports. This
started as an emergency feature branch and went on for a long time, so
it's all been squashed down into one commit so there isn't a big set of
broken commits lying around. The changes are:
* You can pass "-rtos riscv" to the target in OpenOCD's configuration
file, which enables multi-hart mode. This uses OpenOCD's RTOS
support to control all the harts from the debug module using commands
like "info threads" in GDB. This support is still expermental.
* There is support for RV64I, but due to OpenOCD limitations we only
support 32-bit physical addresses. I hope to remedy this by rebasing
onto the latest OpenOCD release, which I've heard should fix this.
* This matches the latest draft version of the RISC-V debug spec, as of
April 26th. This version fixes a number of spec bugs and should be
close to the final debug spec.

This patch adds ChibiOS/RT support. This patch requires at least
ChibiOS/RT development version starting from SVN revision 4734.
Note, that the Thread structures depend not only on the target
but also on the ChibiOS configuration at build time.
To correct this ChibiOS includes a new "memory signature" which
specifies the offsets.
Special thanks go to Peter Stuge and Spencer Oliver for their
continous input and feedback to this patch.
