Calling ensurePeers outside of ensurePeersRoutine can lead to nodes

* 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.

persistent. Fixes#3362

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

* reorder checks in addrbook#addAddress so
ErrAddrBookPrivate is returned first

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.
* failing test
* fix infinite loop in addrbook
There are cases where we only have a small number of addresses marked
good ("old"), but the selection mechanism keeps trying to select more of these
addresses, and hence ends up in an infinite loop. Here we fix this to
only try and select such "old" addresses if we have enough of them. Note this
means, if we don't have enough of them, we may return more "new"
addresses than otherwise expected by the newSelectionBias.
This whole GetSelectionWithBias method probably needs to be rewritten,
but this is a quick fix for the issue.
* changelog
* fix infinite loop if not enough new addrs
* fix another potential infinite loop
if a.nNew == 0 -> pickFromOldBucket=true, but we don't have enough items
(a.nOld > len(oldBucketToAddrsMap) false)
* Revert "fix another potential infinite loop"
This reverts commit 146540c112.
* check num addresses instead of buckets, new test
* fixed the int division
* add slack to bias % in test, lint fixes
* Added checks for selection content in test
* test cleanup

* p2p/conn: FlushStop. Use in pex. Closes#2092
In seed mode, we call StopPeer immediately after Send.
Since flushing msgs to the peer happens in the background,
the peer connection is often closed before the messages are
actually sent out. The new FlushStop method allows all msgs
to first be written and flushed out on the conn before it is closed.
* fix dummy peer
* typo
* fixes from review
* more comments
* ensure pex doesn't call FlushStop more than once
FlushStop is not safe to call more than once,
but we call it from Receive in a go-routine so Receive
doesn't block.
To ensure we only call it once, we use the lastReceivedRequests
map - if an entry already exists, then FlushStop should already have
been called and we can return.
