* require block.Time of the fist block to be genesis time
Refs #2587:
```
We only start validating block.Time when Height > 1, because there is no
commit to compute the median timestamp from for the first block. This
means a faulty proposer could make the first block with whatever time
they want.
Instead, we should require the timestamp of block 1 to match the genesis
time.
I discovered this while refactoring the ValidateBlock tests to be
table-driven while working on tests for #2560.

E[09-24|10:13:15.805] Not stopping PubSub -- have not been started yet module=pubsub impl=PubSub
```
being printed on exit
We are swapping the exisiting listener implementation with the newly
introduced Transport and its default implementation MultiplexTransport,
removing a large chunk of old connection setup and handling scattered
over the Peer and Switch code. The Switch requires a Transport now and
handles externally passed Peer filters.
This is the implementation for the design described in ADR 12[0]. It's
the first step of a larger refactor of the p2p package as tracked in
interface bundling all concerns of low-level connection handling and
isolating the rest of peer lifecycle management from the specifics of
the low-level internet protocols. Even if the swappable implementation
will never be utilised, already the isolation of conn related code in
one place will help with the reasoning about execution path and
addressation of security sensitive issues surfaced through bounty
programs and audits.
We deliberately decided to not have Peer filtering and other management
in the Transport, its sole responsibility is the translation of
connections to Peers, handing those to the caller fully setup. It's the
responsibility of the caller to reject those and or keep track. Peer
filtering will take place in the Switch and can be inspected in a the
following commit.
This changeset additionally is an exercise in clean separation of logic
and other infrastructural concerns like logging and instrumentation. By
leveraging a clean and minimal interface. How this looks can be seen in
a follow-up change.

* ignore existing peers in DialPeersAsync
Fixes#2253
* rename HasPeerWithAddress to IsDialingOrExistingAddress
[breaking] remove Switch#IsDialing
* check if addrBook is nil
to be consistent with other usages of addrBook across Switch
* different log messages for 2 use-cases
* update secret connection to use a little endian encoded nonce
* update encoding of chunk length to be little endian, too
* update comment
* Change comment slightly to trigger circelci
* [p2p/pex] connect to more than 10 peers
also, remove DefaultMinNumOutboundPeers because a) I am not sure it's
needed b) it's super confusing
look closely
```
maxPeers := sw.config.MaxNumPeers - DefaultMinNumOutboundPeers
if maxPeers <= sw.peers.Size() {
sw.Logger.Info("Ignoring inbound connection: already have enough peers", "address", inConn.RemoteAddr().String(), "numPeers", sw.peers.Size(), "max", maxPeers)
```
we print maxPeers = config.MaxPeers - DefaultMinNumOutboundPeers. So we
may not have enough peers even though we say we have enough.
Refs #2130
* update spec
* replace MaxNumPeers with MaxNumInboundPeers/MaxNumOutboundPeers
Refs #2130
* update changelog
* make max rpc conns formula visible to users
* update spec
* docs: note max outbound peers excludes persistent
* p2p/pex: Allow configured seed nodes to be offline
Previously you couldn't startup tendermint if a seed node was offline.
This now allows you to startup tendermint, as long as all seed node addresses
are formatted correctly. In the event that all seed nodes are down,
and the address book is empty, then it crashes with an informative error msg.
(This case doesn't occur if no seeds were specified)
Closes#1716
* (Squash this) Address melekes' comments
* (squash this) fix package imports
* (squash this) fix pex_reactor comment
* (squash this) add a test case
This is to reduce wait times when initially connecting. This still runs checks
such as whether you still want additional peers.
A test case has been created, which fails if this change is not included.
This now uses one hkdf on the X25519 shared secret to create
a key for the sender and receiver.
The hkdf call is now just called upon the computed shared
secret, since the shared secret is a function of the pubkeys.
The nonces now start at 0, as we are using chacha as a stream
cipher, and the sender and receiver now have different keys.
Generate keys with HKDF instead of hash functions, which provides better security properties.
Add xchacha20poly1305 to secret connection. (Due to rebasing, this code has been removed)
Currently the top level directory contains basically all of the code
for the crypto package. This PR moves the crypto code into submodules
in a similar manner to what `golang/x/crypto` does. This improves code
organization.
Ref discussion: https://github.com/tendermint/tendermint/pull/1966Closes#1956
This commit switches all usage of math/rand to cmn's rand. The only
exceptions are within the random file itself, the tools package, and the
crypto package. In tools you don't want it to lock between the go-routines.
The crypto package doesn't use it so the crypto package have no other
dependencies within tendermint/tendermint for easier portability.
Crypto/rand usage is unadjusted.
Closes#1343
