I think all of the request handlers present in gbridge are here now. Now
it needs to be optimized (a lot) and maybe try making the driver a bit
slower?

- Cleanup unused node_table and node_handler
- Move node discovery to main thread

Signed-off-by: Ayush Singh <ayushsingh1325@gmail.com>

Works a bit better. k_yield only yields to threads with higher
priority. Also, get manifest request is not completed even now. That
request took quite a while to complete even when called from zephyr, so
its even worse when hopping from socket and then hdlc.

Not exactly working great. The current performance is subpar. But at
least AP asks for manifest now.

Signed-off-by: Ayush Singh <ayushsingh1325@gmail.com>

AP even sends the protocol version request to node to which it replies,
but it does not seem to reach the AP in time. Seems like a lot of
performance optimizations are needed in zephyr application.

All the initial svc requests sent by AP seem to be somewhat working now.
However, something goes wrong after a number of Pings. Maybe some kind
of memory leak?

Added SVC requests which have empty payload responses

AP gets pretty chatty after hello request. Will need to implement lot
more svc responses.

Now just using a simple message handler.

In the current architecture, gb operations is only used to track SVC
operations. But it is not particularly useful for that either. So just
removing it for now.

Since I will be getting JTAG stuff soon, I will be pausing trying to
debug why taskstat is not working. Also, since taskstat is not working,
it would be best to pause MCUboot stuff since it failing might be
impossible to deal with until I get JTAG
