* Updating go-ipld-prime to NodeAssembler era.

The 'testutil/chaintypes' codegen is currently dropped, and I ported
the testchain fixtures to using basicnode instead.  We can restore this
to using codegen soon, but it's easier to complete this set of changes
by temporarily switching to using basicnode.

Tests using 'NewUnencodableSelectorSpec' were discarded -- this more or
less exercised what would happen if an uninitialized zero value got
into a program, and this is now happily statically impossible.

Some tests are not passing; have not sussed yet.

Remove the encode and decode on ipldbridge as part of ramp up to removing entirely
Also move selector encode/decode to within protobuf encoding

To reduce future import cycles, and expose more types properly, move the root package to an
interface/types file and move the main implementation into /impl. This also exposes an interface
other implementers can replace.

return a boolean instead of an error if an extention is found on a message

Per https://github.com/ipld/specs/pull/205, metadata is now an extension, and further extensions
will be added soon

Previously, we allowed the last message send attempt to run to maxRetries if the queue was shutdown,
which also generated warning logs. Now, if a send attempt fails, check that the queue has shutdown
and immediately return if it has

Adds callbacks to manage connections, also removes network receiver methods from public graphsync
interface, and updates libp2p to handle go-libp2p-core refactor

Updates IPLD Bridge to use latest go-ipld-prime and runs and actual round trip test using GraphSync,
go-ipld-prime, and real selectors

Convert GraphSyncRequest and GraphSyncResponse to structs, track by value, pass directly into add
methods on GraphSyncMessage

Add the ability to send blocks and receive notification when complete to messagequeue

Create a message queue to pool messages for a single peer and send them
