Print out which port OpenOCD is listening on.
...
This is essential when a test environment asks OpenOCD to listen on port
0, so that the environment can easily discover which port is actually
being used.

Share trigger code between 0.11 and 0.13 code.
...
The actual implementation of triggers didn't change between those two
versions, so there's no need to duplicate the code.
In the process, I also fixed a minor multicore bug where tselect didn't
always get written on all harts.

Try using abstract commands to read registers
...
This is the only way the spec guarantees that GPRs are accessible, and
depending on the implementation this might be the only way that CSRs are
accessible.
Also changed the debug code that parses out DMI fields to be simpler to
maintain (albeit a little slower).
riscv013_execute_debug_buffer() now automatically clears cmderr if the
command fails. That feels like the right behavior. (It does return the
error to its caller.)

Disable debugger-set triggers on connect
...
When first connecting to a target, have the debugger disable any
hardware triggers that are set by a previously connected debugger.
The 0.11 code already did this, but 0.13 did not.
To achieve this I decided to share the code to enumerate triggers
between 0.11 and 0.13, which required me to implement get_register() and
set_register() for 0.11, which made the whole change a lot larger than
you might have guessed.
Hopefully this sets us up to in the future share the code to set/remove
triggers as well.
