switch to new sync/atomic helpers in go1.19 (#728) 
These new helpers make the code a lot cleaner. I confirmed that the
simple helpers like `atomic.Int64` don't add any extra overhead as they
get inlined by the compiler. `atomic.Pointer` adds an extra method call
as it no longer gets inlined, but we aren't using these on the hot path
so it is probably okay.

Fix most known data races (#396) 
This change fixes all of the known data races that `make smoke-docker-race` finds, except for one.

Most of these races are around the handshake phase for a hostinfo, so we add a RWLock to the hostinfo and Lock during each of the handshake stages.

Some of the other races are around consistently using `atomic` around the `messageCounter` field. To make this harder to mess up, I have renamed the field to `atomicMessageCounter` (I also removed the unnecessary extra pointer deference as we can just point directly to the struct field).

The last remaining data race is around reading `ConnectionInfo.ready`, which is a boolean that is only written to once when the handshake has finished. Due to it being in the hot path for packets and the rare case that this could actually be an issue, holding off on fixing that one for now.

here is the results of `make smoke-docker-race`:

before:

    lighthouse1: Found 2 data race(s)
    host2:       Found 36 data race(s)
    host3:       Found 17 data race(s)
    host4:       Found 31 data race(s)

after:

    host2: Found 1 data race(s)
    host4: Found 1 data race(s)
