This is the first step in running a full DSP topology on multiple testbench
"virtual" cores. Testbench will use threads to virtualise a emulate a core
allowing topologies with more than one core to run simultaneously.
This patch makes the following changes.
1) Adds and passes a topology testbench context to all APIs instead of
relying on some globals.
2) Splits the testbench up into small functions that have a single purpose.
3) Creates a thread for each pipeline which in turn share a virtual core.
4) Adds the command line options to enable testing different cores and
pipelines.

Implement the fuzzer API for the i.MX8 platform. The difference
between other platforms and i.MX8 is the Messaging Unit(MU). We have
emulated the hardware functionality of MU by using SHMs to represent
Side A and Side B of the MU and the registers they each have. Both
qemu(VM) and fuzzer's write functions write to both sides of the MU to
successfully emulate it's functionality.

This commit introduces the ingredients required for adding
fuzzing support in SOF. The main ingredients are as follows:
QEMU bridge: This creates the IO bridge to communicate with
the QEMU DSP
Core IA host support for BYT/CHT platforms: Provides the host
support for intializing the platform and communicating with
the QEMU DSP
Main application: The fuzzing application that sets up the
platform and initializes the communication with the QEMU DSP
Currently, running the fuzzer application only sets up the
platform IO bridge for communicating with the QEMU DSP,
boots the FW, parses the topology file and sets up the components
and connections in topology by sending the IPC messages to
the QEMU DSP. The next step is to add the fuzzing component
which will be responsible for sending fuzzed IPC messages
and monitoring the status.
