[Pdbg] [PATCH v2] libpdbg: Add a hardware unit for the processor module

[Amitay Isaacs]

From: Alistair Popple <alistair at popple.id.au>

The processor target is a purely logical target but it can be useful
for storing processor wide properties. This means an easy way of
iterating over the processor targets is required, so add a hardware
unit which assigns them to a specific class.
