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.

* update comment
* use MaxInt64 func
* 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
because it's not an error
added block requests under peer
moved the request trigger in the reactor poolRoutine, triggered now by a ticker
in general moved everything required for making block requests smarter in the poolRoutine
added a simple map of heights to keep track of what will need to be requested next
added a few more tests
ListOfKnownAddresses is removed
panic if addrbook size is less than zero
CrawlPeers does not attempt to connect to existing or peers we're currently dialing
various perf. fixes
improved tests (though not complete)
move IsDialingOrExistingAddress check into DialPeerWithAddress (Fixes#2716)
* addrbook: preallocate memory when saving addrbook to file
* addrbook: remove oldestFirst struct and check for ID
* oldestFirst replaced with sort.Slice
* ID is now mandatory, so no need to check
* addrbook: remove ListOfKnownAddresses
GetSelection is used instead in seed mode.
* addrbook: panic if size is less than 0
* rewrite addrbook#saveToFile to not use a counter
* test AttemptDisconnects func
* move IsDialingOrExistingAddress check into DialPeerWithAddress
* save and cleanup crawl peer data
* get rid of DefaultSeedDisconnectWaitPeriod
* make linter happy
* fix TestPEXReactorSeedMode
* fix comment
* add a changelog entry
* Apply suggestions from code review

* rename ErrDialingOrExistingAddress to ErrCurrentlyDialingOrExistingAddress
* lowercase errors
* do not persist seed data
pros:
- no extra files
- less IO
cons:
- if the node crashes, seed might crawl a peer too soon
* 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!

* 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.
