Jason A. Donenfeld 28c4d04304 device: use atomic access for unlocked keypair.next
Go's GC semantics might not always guarantee the safety of this, and the
race detector gets upset too, so instead we wrap this all in atomic
accessors.

David Crawshaw 203554620d conn: introduce new package that splits out the Bind and Endpoint types
The sticky socket code stays in the device package for now,
as it reaches deeply into the peer list.

This is the first step in an effort to split some code out of
the very busy device package.

David Anderson 3dce460c88 device: add test to ensure Peer fields are safe for atomic access on 32-bit
Adds a test that will fail consistently on 32-bit platforms if the
struct ever changes again to violate the rules. This is likely not
needed because unaligned access crashes reliably, but this will reliably
fail even if tests accidentally pass due to lucky alignment.

Jason A. Donenfeld 3371f8dac6 device: update transfer counters correctly
The rule is to always update them to the full packet size minus UDP/IP
encapsulation for all authenticated packet types.
