build(deps): bump github.com/libp2p/go-libp2p-core from 0.6.1 to 0.8.6

[dependabot-preview]

Bumps github.com/libp2p/go-libp2p-core from 0.6.1 to 0.8.6.

Release notes

Sourced from github.com/libp2p/go-libp2p-core's releases.

v0.8.5

Introduces a context option to signify simultaneous connect for hole punching.

v0.8.4

Introduces an Event to detect TCP & UDP NAT Device Type.

v0.8.3

Adds support for forcing a direct connection with a peer even if we already have a relayed connection.

v0.8.2

• #175 -- Adds support for transient connections.

v0.8.1

• Introduce a sec.SecureMuxer interface which can select security protocols and open outbound connections with simultaneous open. It is a wrapper around the SecureTransport interface.

v0.8.0 introduces a BREAKING interface change: MuxedConn.OpenStream and Conn.NewStream now both take a context.Context. This allows stream multiplexer implementations to unblock OpenStream when requested to do so.

Release v0.7.0

This is release includes a significant BREAKING CHANGE to the stream interface.

Previously, Close() closed streams for writing, but left them open for reading. Unfortunately, this meant streams would not be garbage collected until either (a) an EOF had been read on the stream or (b) Reset had been called. While technically documented, this behavior was extraordinarily surprising and most libp2p applications end up misusing and leaking streams (leading to memory leaks).

A CloseRead function has been introduced to close a stream for reading only (writing is still allowed).

• Any in-progress Read calls will be interrupted with a non-EOF error.
• No further calls to Read will succeed.
• The handling of new incoming data on the stream after calling close is implementation defined. Currently,
  • Yamux and Mplex will throw away incoming data on a closed stream.
  • QUIC will return an error to the sender.

Close now closes the stream for both reading and writing. Close is equivalent to calling CloseRead and CloseWrite. Importantly, Close will not wait for any form of acknowledgment. If acknowledgment is required, the caller must call CloseWrite, then wait on the stream for a response (or an EOF), then call Close() to free the stream object.

When done with a stream, the user must call either Close() or Reset() to discard the stream, even after calling CloseRead() and/or CloseWrite().
