I'm setting up all peers dynamically by calling dial_peers, so p2p.seeds in configs is empty, and I'm seeing error log a lot in logs.
* p2p: fix false-positive error logging when stopping connections
This changeset fixes two types of false-positive errors occurring during
connection shutdown.
The first occurs when the process invokes FlushStop() or Stop() on a
connection. While the previous behavior did properly wait for the sendRoutine
to finish, it did not notify the recvRoutine that the connection was shutting
down. This would cause the recvRouting to receive and error when reading and
log this error. The changeset fixes this by notifying the recvRoutine that
the connection is shutting down.
The second occurs when the connection is terminated (gracefully) by the other side.
The recvRoutine would get an EOF error during the read, log it, and stop the connection
with an error. The changeset detects EOF and gracefully shuts down the connection.
* bring back the comment about flushing
* add changelog entry
* listen for quitRecvRoutine too
* we have to call stopForError
Otherwise peer won't be removed from the peer set and maybe readded
later.

* p2p/pex: consult seeds in crawlPeersRoutine
This changeset alters the startup behavior for crawlPeersRoutine. Previously
the routine would crawl a random selection of peers on startup. For a
new seed node, there are no peers. As a result, new seed nodes are unable
to bootstrap themselves with a list of peers until another node with a list
of peers connects to the seed. If this node relies on the seed node for peers,
then the two will not discover more peers.
This changeset makes the startup behavior for crawlPeersRoutine connect to
any seed nodes. Upon connecting, a request for peers will be sent to the seed node
thus helping bootstrap our seed node.

We don't need it actually.
If we are low on addresses for peering, we need to discover more peers. The
previous behavior would query existing peers; however, if an existing peer
does not participate in peer exchange, then our node will not discover more peers.
This change consults both existing peers as well as seeds when there is a deficit
in address book addresses. This allows for discovering peers though existing channels
as well as via seeds if existing peers do not share addresses.
* Remove deprecated PanicXXX functions from codebase
As per discussion over
[here](https://github.com/tendermint/tendermint/pull/3456#discussion_r278423492),
we need to remove these `PanicXXX` functions and eliminate our
dependence on them. In this PR, each and every `PanicXXX` function call
is replaced with a simple `panic` call.
* add a changelog entry
* use dialPeer function in a seed mode
Fixes#3532
by storing a number of attempts we've tried to connect in-memory and
removing the address from addrbook when number of attempts > 16
A prior change to address accidental DNS lookups introduced the
SocketAddr on peer, which was then used to add it to the addressbook.
Which in turn swallowed the self reported port of the peer, which is
important on a reconnect. This change revives the NetAddress on NodeInfo
which the Peer carries, but now returns an error to avoid nil
dereferencing another issue observed in the past. Additionally we could
potentially address #3532, yet the original problem statemenf of that
issue stands.
As a drive-by optimisation `MarkAsGood` now takes only a `p2p.ID` which
makes it interface a bit stricter and leaner.
* add actionable advice for ErrAddrBookNonRoutable err
Should replace https://github.com/tendermint/tendermint/pull/3463
* reorder checks in addrbook#addAddress so
ErrAddrBookPrivate is returned first
and do not log error in DialPeersAsync if the address is private

ListOfKnownAddresses is removed

CrawlPeers does not attempt to connect to existing or peers we're currently dialing

* fixes after Ethan's review
* add a changelog entry
* we should only consult Switch about peers
checking addrbook size does not make sense since only PEX reactor uses
it for dialing peers!
https://github.com/tendermint/tendermint/pull/3011#discussion_r270948875
* OriginalAddr -> SocketAddr
OriginalAddr records the originally dialed address for outbound peers,
rather than the peer's self reported address. For inbound peers, it was
nil. Here, we rename it to SocketAddr and for inbound peers, set it to
the RemoteAddr of the connection.
* use SocketAddr
Numerous places in the code call peer.NodeInfo().NetAddress().
However, this call to NetAddress() may perform a DNS lookup if the
reported NodeInfo.ListenAddr includes a name. Failure of this lookup
returns a nil address, which can lead to panics in the code.
Instead, call peer.SocketAddr() to return the static address of the
connection.
* remove nodeInfo.NetAddress()
Expose `transport.NetAddress()`, a static result determined
when the transport is created. Removing NetAddress() from the nodeInfo
prevents accidental DNS lookups.

Why submit this pr:
we have suffered from infinite loop in addrbook bug which takes us a long time to find out why process become a zombie peer. It have been fixed in #3232. But the ADDRS_LOOP is still there, risk of infinite loop is still exist.
The algorithm that to random pick a bucket is not stable, which means the peer may unluckily always choose the wrong bucket for a long time, the time and cpu cost is meaningless.
A simple improvement:
shuffle bucketsNew and bucketsOld, and pick necessary number of address from them. A stable
algorithm.

This fixes two small bugs:
1) lite/dbprovider: return `ok` instead of true in parse* functions. It's weird that we're ignoring `ok` value before.
2) consensus/state: previously because of the shadowing we almost never output "Error with msg". Now we declare both `added` and `err` in the beginning of the function, so there's no shadowing.
* fix dirty data in peerset
startInitPeer before PeerSet add the peer,
once mconnection start and Receive of one
Reactor faild, will try to remove it from PeerSet
while PeerSet still not contain the peer. Fix
this by change the order.
* fix test FilterDuplicate
* fix start/stop race
