Implement the RX pipeline

[pavel-kirienko]

• Implement the common parts of the RX pipeline. At this point, about 90% of the work is done. All that is left is to add the basic public API wrappers for subscriptions and RPC-services. For details about the implementation of the RX pipeline refer to the line that says "Internally, the RX pipeline is arranged as follows".

• Slightly refactor the code added earlier to uphold orthogonality and avoid unnecessary duplication.

• Trivial renamings to keep names shorter, e.g.:

  • UdpardConstPayload -> UdpardPayload (const implied by default; there's also UdpardMutablePayload)
  • UdpardPayloadFragmentHandle -> UdpardFragment

• Establish an internal convention that functions named "Destroy" deallocate the passed memory while "Free" only deallocate the memory of the associated resources. This is not API-visible.

• Remove the port_id field from UdpardRxPort because it is not needed.

After this is merged, the remaining task is to simply implement the public RX pipeline functions on top of:

• rxPortInit
• rxPortAcceptFrame
• rxPortFree

The test coverage is supposed to be full but llvm-cov slightly misreports it.
