Fixes the following test race condition:
```
=== RUN TestAppCalls
TestAppCalls: rpc_test.go:216:
Error Trace: rpc_test.go:216
Error: Expected value not to be nil.
Test: TestAppCalls
--- FAIL: TestAppCalls (2.20s)
```
Attempt to fix this the below test failure by waiting for the listener to get ready. I am not at all convinced that this is the correct fix - the below indicates that the TCP socket was closed after it was set up - but I'm unable to come up with an actionable hypothesis for what caused it.

## Description
In https://github.com/tendermint/tendermint/pull/4466 a new type was created (EventAttribute) that replaced KV.Pair. This made the type Pair deadcode, this pr removes that type.
I don't think a changelog entry is needed since it is not being used anymore. But will add a section to the upgrading.md to let users know that it was replaced
Closes: #XXX
* p2p: log error in transport tests
* p2p: exit from fast peer only when handshake is done
TestTransportMultiplexAcceptNonBlocking
fixes panic: write to a closed channel
* p2p: increase timeout in TestTransportMultiplexConnFilterTimeout
Fixes https://github.com/tendermint/tendermint/issues/4854#issuecomment-630739200
* p2p: yield control to another goroutine manually
* increase timeout in TestTransportMultiplexAcceptNonBlocking
## Description
by adding paths the ci job wont run if the files aren't touched. this is a change from before where they would run to see if there were changes
Closes: #XXX
## Description
bech32 is only used in the sdk. I moved Bech32 to the sdk and we can remove it here. Don't think this needs to go into a minor release
Closes: #XXX
Closes#4603
Commands used (VIM):
```
:args `rg -l errors.Wrap`
:argdo normal @q | update
```
where q is a macros rewriting the `errors.Wrap` to `fmt.Errorf`.
## Description
regenerate proto stubs
I do find max_num to be vague. possibly renaming to max_entries or max_evidence_entries may be more descriptive?
Closes: #XXX
creates a proof of lock change which is an array of votes that proves the validator was permitted to change locked block and vote again. This proof is stored in the evidence pool and is used as a part of amnesia evidence
Debian testing caused Docker image build failures:
```
The following packages have unmet dependencies:
libc6-dev : Breaks: libgcc-8-dev (< 8.4.0-2~) but 8.3.0-6 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
```
It does not appear that we actually need testing, so removing it.
Fix some linter issues to conform with the Protobuf style guide.
The state sync enum changes are ok to break since it's not released yet. Personally I find the uppercase kind of ugly, but that's what the guide says. Couldn't find a way to generate camel case in Go, short of specifying custom names for each and every enum variant.
Another option would be to simply disable the enum case lint.
Integrates the blockchain v2 reactor with state sync, fixes#4765. This mostly involves deferring fast syncing until after state sync completes. I tried a few different approaches, this was the least effort:
* `Reactor.events` is `nil` if no fast sync is in progress, in which case events are not dispatched - most importantly `AddPeer`.
* Accept status messages from unknown peers in the scheduler and register them as ready. On fast sync startup, broadcast status requests to all existing peers.
* When switching from state sync, first send a `bcResetState` message to the processor and scheduler to update their states - most importantly the initial block height.
* When fast sync completes, shut down event loop, scheduler and processor, and set `events` channel to `nil`.
