remove send lock (#334)
* remove send lock

When mplex receives data it will block until a reader has processed the
data. Thus, when a large message is received, such as a gossipsub
subscription table, all of mplex will be blocked until all reading is
finished.

However, if at the same time a `dial` to establish a gossipsub send
connection is ongoing, that `dial` will be blocked because mplex is no
longer reading data - specifically, it might indeed be the connection
that's processing the previous data that is waiting for a send
connection.

There are other problems with the current code:
* If an exception is raised, it is not necessarily raised for the same
connection as `p.sendConn`, so resetting `p.sendConn` in the exception
handling is wrong
* `p.isConnected` is checked before taking the lock - thus, if it
returns false, a new dial will be started. If a new task enters `send`
before dial is finished, it will also determine `p.isConnected` is
false, then get stuck on the lock - when the previous task finishes and
releases the lock, the new task will _also_ dial and thus reset
`p.sendConn` causing a leak.

* prefer existing connection

simplifies flow

avoid crash when subscribe is received (#333)
...by making subscribeTopic synchronous, avoiding a peer table lookup
completely.

rebalanceMesh will be called a second later - it's fine

peer hooks -> events (#320)
* peer hooks -> events

* peerinfo -> peerid
* include connection direction in event
* check connection status after event
* lock connmanager lookup also when dialling peer
* clean up un-upgraded connection when upgrade fails
* await peer eventing

* remove join/lifetime future from peerinfo

Peerinfo instances are not unique per peer so the lifetime future is
misleading - it fires when a random connection is closed, not the "last"
one

* document switch values

* naming

* peerevent->conneevent

`msg` is a reserved property name in Chronicles (#321)
Every Chronicles log record has an existing `msg` property matching
the static string supplied in the log statement. Thus, it's currently
not possible to use `msg` as the name of a user property:
