* crypto/secp256k1: Fix signature malleability, adopt more efficient encoding
This removes signature malleability per ADR 14, and makes secp match
the encoding in ADR 15.
* (squash this) add lock
* [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
* mempool: Keep cache hashmap and linked list in sync
This removes bugs with the linked list being full, but hashmap empty
* address PR comments
* switch clist back to list
Now that Tendermint Amino will be compatible with proto3, the Header in ABCI
should exactly match the Tendermint header - they will then be encoded
identically in ABCI and in Tendermint Core.

* 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 uses the stdlib's method of creating a tempfile in our write
file atomimc method, with a few modifications. We use a 64 bit number
rather than 32 bit, and therefore a corresponding LCG. This is to
reduce collision probability. (Note we currently used 32 bytes previously,
so this is likely a concern)
We handle reseeding the LCG in such a way that multiple threads are
even less likely to reuse the same seed.
This PR changes ABCI time format from int64 (Unix seconds) to WKT (WellKnownType) google.protobuf.Timestamp.

Reasons:
better precision
standard DT for proto
* update Gopkg.lock
* [makefile] remove extra grep
- go list excludes vendor by default now
* proto3 timestamp
* [docs/abci-spec] note about serialisation format
* make time non-nullable
This now makes bit array functions which take in a second bit array, thread
safe. Previously there was a warning on bitarray.Update to be lock the
second parameter externally if thread safety wasrequired.
This was not done within the codebase, so it was fine to change here.
Closes#2080
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.
hkdfchachapoly was a construction we came up with. There is no longer any
reason to use it. We should instead just use xchacha for the remaining use
cases we have. (Symmetrically encrypting the keys in the sdk keys package)
This adds a new makefile command, which is used in CI linting, `make check_dep`.
This ensures the toml is in sync with the lock, and that were not pinning to a
branch in any repository.
This also adapts `make get_vendor_deps` to check the lock, in addition to
populating the vendor directory. This removes the need for `make ensure_deps`.
This makes `make get_vendor_deps` consistent between tendermint and the sdk.

We don't use the fee field and its likely just confusing.
We can add backwards compatible priority (instead of fee) later.
Note priority is better than fee because it lets the app do the math on how to rank order transactions, rather than forcing that into tendermint (ie. if we return fee, priority would be fee/gas)
