This commit modifies the base peer struct to ascertain when a peer is
able to understand the new witness encoding, and specify the peer’s
supported encoding explicitly before/after the version handshake.
This changes the nonce generated to detect self connections over to use
pseudo randoms instead of a cryptographically random nonce.
There is really not a good reason for it to be cryptographically strong,
using the prng is much faster, and the prng also doesn't burn entropy.
This removes the field that tracks whether the version has been sent
since it is no longer used after the version negotiation was separated
from the main read and write code.
Replace assignments to individual fields of wire.NetAddress with
creating the entire object at once, as one would do if the type was
immutable.
In some places this replaces the creation of a NetAddress with a
high-precision timestamp with a call to a 'constructor' that converts
the timestamp to single second precision. For consistency, the tests
have also been changed to use single-precision timestamps.
Lastly, the number of allocations in readNetAddress have been reduced by
reading the services directly into the NetAddress instead of first into
a temporary variable.
This modifies the error handling path in the peer read loop such that it
will no longer log an error when the error is io.ErrUnexpectedEOF. This
is being done because that error is almost always the result of a peer
being remotely disconnected and thus it isn't useful information to log.
However, since it might actually be due to a malformed message, a reject
message is still queued up to be sent back to the peer (which will
simply be discarded if the peer disconnected) before it is disconnected.
While it would be ideal to only log if it's not due to a disconnect, and
the code already attempts to handle that, it's not 100% possible to
detect upon the read returning an error without attempting to read again
which will not happen until the next loop iteration.
The inability for a peer to negotiate is not something that should be a
warning which implies something is wrong. On the contrary, it is quite
expected that various peers will connect (or be connected to) that are
unable to properly negotiate for a variety of reasons. One example would
be a peer that is too old.
Also, while here take care of a few style nits.
This adds a new field to the peer struct which stores the protocol
version advertised by the remote peer and updates the StatsSnapshot to
return the advertised version instead of the negotiated version.
