refactor: remove WantManager

Send CANCELs when session context is cancelled

refactor: remove unused code

Change timing for DONT_HAVE timeouts to be more conservative

fix: avoid calling ctx.SetDeadline() every time we send a message

* feat: small optimizations

* feat: move broadcast wantlist into the peermanager

This deduplicates some state and allows us to do less book-keeping for broadcast
wants. We should probably rename the PeerManager to the WantManager and rename the
WantManager to something else.

* fix: lint warnings

* refactor: add reverse index to peerWantManager to speed up cancels

* refactor: in peerWantManager use ForEach instead of allocating lists

* fix: minimize time holding wantlist lock

Instead of holding the lock the entire time we prepare a message, hold the lock
while we retrieve the wantlist entries, process the entries without the lock,
retake the lock, then mark entries as sent.

This means:

1. We never sort entries while holding the lock.
2. We allocate exactly three times while holding the lock (once per entry list).

* fix: address code review

feat: optimize entry sorting in MessageQueue

Move connection management into networking layer

There's no reason to launch this async.

Instead of copying these slices, we can just reuse them.

refactor: simplify messageQueue onSent
