Fixes#4051
Function `parseRemoteAddr` is forcing protocol HTTP and protocol HTTPs to tcp. This causes the bug in the issue #4051.
I find that the tcp is only needed where `net.Dial`. So I moved the switch to makeHTTPDialer.
## Issue:
Hey, not sure if this is disallowed for any reason specifically, but it would be very beneficial to define additional types to decode tendermint key implementations from bytes, since it uses a static codec. If this is okay, let me know and I will add documentation.
Context: For Ethermint to switch to using Cosmos' keybase, decoding the keys requires this codec to be updated
Just to document, I did experiment with creating a mapping from string to objects to be able to keep track of the key types added to be able to be used in the RegisterAmino(..) call, but because of how go is compiled, cosmos would just use the base types. This may be a useful feature for someone just building on top of Tendermint and not going through Cosmos, but to not add confusion or unnecessary complexity, I left it out.
## Commits:
* Exposes amino codec to be able to decode pk bytes in application
* Change how codec is modified
* Remove unneeded comment
* Fix comment
* Fix comment
* Add registered type to nametable
* Add pending changelog entry
* Reorder change
* Added check if type is registered and added test
* Make test type private
* Remove unnecessary duplicate exists check
Added a small function to be able to change the default retry interval for the privval. The default is 100ms, this function allows to change to any time.Duration.

## Issue:
This PR adds an "EXISTS" condition to the event query grammar. It enables querying for the occurrence of an event without having to provide a condition for one of its attributes.
As an example, someone interested in all slashing events might currently catch them with a query such as slash.power > 0.
With this PR the event can be captured with slash.power EXISTS or just slash EXISTS to catch by event type.
## Examples:
`slash EXISTS`

when the user searches for a tx (hash=X)
This PR fixes error handling for performing a txindex search.
TxIndex.Get returns
(txresult, nil) if the transaction is found.
(nil, nil) if the transaction is not found.
(nil, error) if error is occurred.
Therefore, if res is not nil, I think TxIndex.Search should return (txresult, nil).
Previously, however, this was not a problem because errors.Wrap returns nil if its first argument err is nil.
## Issue
Why this pr:
When restarting chain node, sometimes we lost tx index about recent(around 80)blocks, and some client complains that they can't find the tx by RPC call(tx_search) when the tx do exist in the block.
I try to partially fix this issue in a simple way by writing the index data in a sync way.
There is no performance difference under 1K TPS according to our test.
It is still possible that lost index data after restarting the node, but only 2 block data will lost at most.
I try to totally fix this in https://github.com/tendermint/tendermint/pull/3847/files, but this one is simple and can solve most part of the issue. Please review first, thks.

* Updated CHANGELOG_PENDING
* Added PR number to CHANGELOG_PENDING.
Improves `tm-monitor` formatting of start time (RFC1123 without unnecessary precision) and avg tx throughput (three decimal places). The old tx throughput display was confusing during local testing where the tx rate is low and displayed as 0.
Also updates the monitor health whenever the validator number changes. It otherwise starts with moderate health and fails to update this once it discovers the validators, leading to incorrect health reporting and invalid uptime statistics. Let me know if you would like me to submit this as a separate PR.

This PR is related to #3107 and a continuation of #3351
It is important to emphasise that in the privval original design, client/server and listening/dialing roles are inverted and do not follow a conventional interaction.
Given two hosts A and B:
Host A is listener/client
Host B is dialer/server (contains the secret key)
When A requires a signature, it needs to wait for B to dial in before it can issue a request.
A only accepts a single connection and any failure leads to dropping the connection and waiting for B to reconnect.
The original rationale behind this design was based on security.
Host B only allows outbound connections to a list of whitelisted hosts.
It is not possible to reach B unless B dials in. There are no listening/open ports in B.
This PR results in the following changes:
Refactors ping/heartbeat to avoid previously existing race conditions.
Separates transport (dialer/listener) from signing (client/server) concerns to simplify workflow.
Unifies and abstracts away the differences between unix and tcp sockets.
A single signer endpoint implementation unifies connection handling code (read/write/close/connection obj)
The signer request handler (server side) is customizable to increase testability.
Updates and extends unit tests
A high level overview of the classes is as follows:
Transport (endpoints): The following classes take care of establishing a connection
SignerDialerEndpoint
SignerListeningEndpoint
SignerEndpoint groups common functionality (read/write/timeouts/etc.)
Signing (client/server): The following classes take care of exchanging request/responses
SignerClient
SignerServer

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.

* Fix bug in sendRequest()
If we tried to send a request to a peer not present in the switch, a
missing continue statement caused the request to be blackholed in a peer
that was removed and never retried.
While this bug was manifesting, the reactor kept asking for other
blocks that would be stored and never consumed. Added the number of
unconsumed blocks in the math for requesting blocks ahead of current
processing height so eventually there will be no more blocks requested
until the already received ones are consumed.
