Updates all deps needed to support passing lists of byte arrays where they have been created from multiple input buffers.
When reading multiplexed data, all messages arrive in length-prefixed buffers, which means the first few bytes tell the consumer how many bytes long next chunk will be.
One length prefixed chunk can be delivered in several payloads from the underlying network transport. The first payload can also include the length prefix and some or all of the data, so we stitch these together in a `Uint8ArrayList` to avoid having to concatenate `Uint8Array`s together.
Previously once we'd received enough bytes to satisfy the length prefix we'd concatenate the bytes together, but this is a potentially expensive operation where transports have small message sizes so instead just pass the `Uint8ArrayList` to the consumer and let them decide wether to concatenate or not as some consumers will be smart enough to operate on lists of `Uint8Array`s instead of always requiring a contiguous block of memory.
BREAKING CHANGE: Streams are now `Duplex<Uint8ArrayList, Uint8ArrayList | Uint8Array>`
Now that we need to build ts to js a build step is necessary.
Add it to the instructions where we are telling people to clone the repo first.

* feat: limit protocol streams per-connection
Uses the `maxInboundStreams` and `maxOutboundStreams` of the `registrar.handle`
opts to limit the number of concurrent streams open on each connection
on a per-protocol basis.
Both values default to 1 so some tuning will be necessary to set
appropriate values for some protocols.
* chore: make error codes consistent
* chore: fix up examples
Converts this module to typescript.
- Ecosystem modules renamed from (e.g.) `libp2p-tcp` to `@libp2p/tcp`
- Ecosystem module now have named exports
- Configuration has been updated, now pass instances of modules instead of classes:
- Some configuration keys have been renamed to make them more descriptive. `transport` -> `transports`, `connEncryption` -> `connectionEncryption`. In general where we pass multiple things, the key is now plural, e.g. `streamMuxer` -> `streamMuxers`, `contentRouting` -> `contentRouters`, etc. Where we are configuring a singleton the config key is singular, e.g. `connProtector` -> `connectionProtector` etc.
- Properties of the `modules` config key have been moved to the root
- Properties of the `config` config key have been moved to the root
```js
// before
import Libp2p from 'libp2p'
import TCP from 'libp2p-tcp'
await Libp2p.create({
modules: {
transport: [
TCP
],
}
config: {
transport: {
[TCP.tag]: {
foo: 'bar'
}
},
relay: {
enabled: true,
hop: {
enabled: true,
active: true
}
}
}
})
```
```js
// after
import { createLibp2p } from 'libp2p'
import { TCP } from '@libp2p/tcp'
await createLibp2p({
transports: [
new TCP({ foo: 'bar' })
],
relay: {
enabled: true,
hop: {
enabled: true,
active: true
}
}
})
```
- Use of `enabled` flag has been reduced - previously you could pass a module but disable it with config. Now if you don't want a feature, just don't pass an implementation. Eg:
```js
// before
await Libp2p.create({
modules: {
transport: [
TCP
],
pubsub: Gossipsub
},
config: {
pubsub: {
enabled: false
}
}
})
```
```js
// after
await createLibp2p({
transports: [
new TCP()
]
})
```
- `.multiaddrs` renamed to `.getMultiaddrs()` because it's not a property accessor, work is done by that method to calculate announce addresses, observed addresses, etc
- `/p2p/${peerId}` is now appended to all addresses returned by `.getMultiaddrs()` so they can be used opaquely (every consumer has to append the peer ID to the address to actually use it otherwise). If you need low-level unadulterated addresses, call methods on the address manager.
BREAKING CHANGE: types are no longer hand crafted, this module is now ESM only

Array.shift seems to be very slow, perhaps linear, on some

https://github.com/multiformats/js-multiaddr/pull/76 changed the
default protocol from ipfs to p2p.
js-multiaddr is a transitive dependency of peer-info, so in order
to get this change, we had to bump the version of peer-info.
* fix: revert ipfs -> p2p change for some tests
As per PR feedback. Needed for backwards-compatibility.
