…formance of a hub including packet loss.
Adds a structure for recording timestamps per packet.
Adds stats printing timer.
Applies the gridconnect use select link option. Applies the SO_SNDBUF/RCVBUF link option.
When a dispatcher was used to send traffic to a gridconnect bridge, an infinite number of packets were allocated in the dispatcher when more than one client was connected. By adding a limitedpool to the bridge object, we can ensure that the dispatcher is blocked when the output queue pushes back.

…b-test-app * commit '4bd04c6c81b987a82f5f399bd104fb0eeb9b2f7b': Limits end to end buffering in gridconnect bridge.
* bracz-hub-bridge-limit-pool: fix whitespace
* bracz-exec-multi-thread-assert: Ensures that an executor thread can not be created twice.
Applies the gridconnect use select link option. Applies the SO_SNDBUF/RCVBUF link option.
…b-test-app * commit 'ea41047b1bc27c2cc29e4b5ba303b9bb10096009': Refactors the fd optimization code to FdUtils class. Sorts lines in sources. Ensures that the ClientCOnnection.cxx is built and linked. client connection util: exposes the file descriptor when available. Applies the gridconnect use select link option. Applies the SO_SNDBUF/RCVBUF link option. gc-tcp-hub: applies SO_SNDBUF and SO_RCVBUF options to sockets. Optimizes the memory and buffer use of the hub application. Adds constants for TCP socket options fo SO_SNDBUF and SO_RCVBUF
* bracz-optimize-tcp-socket: Adds comment. Fix compile error. Makes tcp_lowat also configurable.
This needs no dedicated memory, but uses the regular mainBufferPool. Add a check that all outgoing packets are released before deleting the pool. This solves hub crashing when a client disconnects.

* bracz-optimize-tcp-socket: Tune TCP options. Switch gridconnect hub to LimitedPool instead of FixedPool. This needs no dedicated memory, but uses the regular mainBufferPool.
- support creating multiple TCP clients with -N number - support sending different packets, like identify producer and verify node ID which allows measuring response latency of a node.
* master: Fix test flakiness. Fix compile error on FdUtils under freertos.

Adds a new application to OpenMRN called hub_test. This application can generate a specific amount of traffic, send it to a bus (a CAN-bus or a gridconnect-TCP hub). A second component is a receiver, which listens to traffic on the same OpenLCB bus. It verifies that data arrives without dropped packets, in order, and prints statistics about throughput and round-trip time (which correlates with buffer length).
