transports:
Transports build on I/O service and implements flow control and
sequence number checking.
The rx streamer subclass extends the streamer implementation to connect
it to the rfnoc graph. It receives configuration values from property
propagation and configures the streamer accordingly. It also implements
the issue_stream_cmd rx_streamer API method.
Add implementation of rx streamer creation and method to connect it to
an rfnoc block.
rfnoc_graph: Cache more connection info, clarify contract
Summary of changes:
- rfnoc_graph stores more information about static connections at the
beginning. Some search algorithms are replaced by simpler lookups.
- The contract for connect() was clarified. It is required to call
connect, even for static connections.

These changes add APIs to instantiate the new transports. However,
only the control/management transport is currently implemented. It
uses the chdr_ctrl_xport.
Also update the mgmt_portal to use an ephemeral reference to the
shared transport, to indicate that it has no ownership of the
transport's memory.

The management looks at the transport endianness from the packet
factory to determine if the byte_swapper in the FPGA needs to be enabled

- chdr_ctrl_endpoint can manage multiple dest EPIDs
- Moved from both_xports_t to a special defs in rfnoc_common
- Changed data-structures where appropriate

|
|
|

- Moved chdr_packet and chdr_types from rfnoc/chdr to rfnoc and updated
all references
- Moved non-CHDR definitions to rfnoc_common.hpp
|

- The management portal is the interface for the framework
to allow discovering the data topology, setup routes between
stream endpoints and configure streamers
- Use a zero_copy_if and the mgmt_paylod to send/recv packets
