Disabling this feature will allow the USRP to send a continuous stream
of Rx data to a host machine without throttling due to lack of flow
control credits. This is unnecessary overhead on lossless transports
such as pcie or aurora.
Usage: add 'enable_fc=false' to stream_args.args

This commit resolves a segfault that occurs during teardown. Since
teardown isn't detereministic in python, there were cases where the
graph would destruct before the streamers or links got chance to
cleanup. This would result in a segfault. This change gives the lambda
a shared pointer to the object the callback method is calling on, so
that it won't destruct before being called.

Transports were not disconnecting their links from the I/O service upon
destruction, leaving behind inaccessible send and recv links used by
nothing. This led to I/O errors after creating several transports.
Added callbacks to transports to automatically disconnect their links
from the I/O service when the transport is destroyed. Updated all
callers to supply a disconnect callback.

DPDK provides a fixed number of fixed-size buffers for the receive
window, so it needs packet-based flow control to avoid dropping
packets. This change enables counting by packets.

This removes the token requirement for get_proto_ver() and
get_chdr_width().

This makes it possible for users to put I/O service-related args in
either the device args or stream args.

- Implement I/O service detach link methods
- The I/O service manager instantiates new I/O services or connects
links to existing I/O services based on options provided by the user
in stream_args.
- Add a streamer ID parameter to methods to create transports so that
the I/O service manager can group transports appropriately when using
offload threads.
- Change X300 and MPMD to use I/O service manager to connect links to
I/O services.
- There is now a single I/O service manager per rfnoc_graph (and it is
also stored in the graph)
- The I/O service manager now also knows the device args for the
rfnoc_graph it was created with, and can make decisions based upon
those (e.g, use a specific I/O service for DPDK, share cores between
streamers, etc.)
- The I/O Service Manager does not get any decision logic with this
commit, though
- The MB ifaces for mpmd and x300 now access this global I/O service
manager
- Add configuration of link parameters with overrides
