Rework the implementation of event query parsing and execution to
improve performance and reduce memory usage.

Previous memory and CPU profiles of the pubsub service showed query
processing as a significant hotspot. While we don't have evidence that
this is visibly hurting users, fixing it is fairly easy and self-contained.

Updates #6439.

Typical benchmark results comparing the original implementation (PEG) with the reworked implementation (Custom):
```
TEST                        TIME/OP  BYTES/OP  ALLOCS/OP  SPEEDUP   MEM SAVING
BenchmarkParsePEG-12       51716 ns  526832    27
BenchmarkParseCustom-12     2167 ns    4616    17         23.8x     99.1%
BenchmarkMatchPEG-12        3086 ns    1097    22
BenchmarkMatchCustom-12    294.2 ns      64     3         10.5x     94.1%
```

Components:
* Add a basic parsing benchmark.
* Move the original query implementation to a subdirectory.
* Add lexical scanner for Query expressions.
* Add a parser for Query expressions.
* Implement query compiler.
* Add test cases based on OpenAPI examples.
* Add MustCompile to replace the original MustParse, and update usage.

The event examples for the query filter language were not updated after the
change of key and value types from []byte to string. Also, the attributes need
to be a slice not a bare value.

Updates #7272.

This is a very small change, but removes a method from the
`service.Service` interface (a win!) and forces callers to explicitly
pass loggers in to objects during construction rather than (later)
injecting them. There's not a real need for this kind of lazy
construction of loggers, and I think a decent potential for confusion
for mutable loggers.

The main concern I have is that this changes the constructor API for
ABCI clients. I think this is fine, and I suspect that as we plumb
contexts through, and make changes to the RPC services there'll be a
number of similar sorts of changes to various (quasi) public
interfaces, which I think we should welcome.

Since the doc site is built from the backport branches, the config changes for
a new major release also need to be replicated into the backport branch as well
as master. Update the release docs to mention that specifically, since I missed
it during the v0.35 release.

This pull request updates the `protocgen.sh` script to insert the `go_package` option to all of the downloaded proto files. A related pull request into the spec repo removes this options from the .proto files: https://github.com/tendermint/spec/pull/358

This pull requests, along with the related spec PR, aim to move the creation of the `tendermintdev/docker-build-proto` container into the spec repo. This change also relies on several fixes to that container that are made in the PR into the spec repo.

I think calling os.Exit at arbitrary points is _bad_ and is good to
delete. I think panics in the case of data courruption have a chance
of providing useful information.

This mostly just pushes more of initialization out of the node package.

* update the proposer-based timestamps spec per discussion with @cason

* add vote to list of changed structs

* sentence fix

* clarify crypto sig logic update

* language updates per feedback from @cason

* fix POL < 0 wording

* update timely description for non-polka

When dialing fails to succeed we should reduce the score of the peer,
which puts the peer at (potentially) greater chances of being removed
from the peer manager, and reduces the chance of the peer being
gossiped by the PEX reactor.

The evidence test produces a set of mock evidence in the evidence pool of the 'Primary' node. The test then fills the evidence pools of secondaries with half of this mock evidence. Finally, the test waits until the secondary has an evidence pool as full as the primary. 

The assertions that are removed here were checking that the primary and secondaries' evidence channels were empty. However, nothing in the test actually ensures that the channels are empty. The test only waits for the secondaries to have received the complete set of evidence, and the secondaries already received half of the evidence at the beginning. It's more than possible that the secondaries can receive the complete set of evidence and not finish reading the duplicate evidence off the channels.

As a safety measure, don't allow a query string to be unreasonably
long. The query filter is not especially efficient, so a query that
needs more than basic detail should filter coarsely in the subscriber
and refine on the client side.

This affects Subscribe and TxSearch queries.

This follows the same model as we did in the p2p package.

Rework the indexer service constructor to take a struct of arguments,
that makes it easier to construct the optional settings.
Deprecate but do not remove the existing constructor.

Clean up node initialization a little bit.

This is part of the work described by #7156.

Remove "unbuffered subscriptions" from the pubsub service.
Replace them with a dedicated blocking "observer" mechanism.
Use the observer mechanism for indexing.

Add a SubscribeWithArgs method and deprecate the old Subscribe
method. Remove SubscribeUnbuffered entirely (breaking).

Rework the Subscription interface to eliminate exposed channels.
Subscriptions now use a context to manage lifecycle notifications.

Internalize the eventbus package.

Oops.

This is intended to document some ergonomic and reliability issues with the
existing implementation of the event subscription service on the Tendermint
node, and to discuss possible approaches to improving them.

A follow-up to #7197.

We were creating a TestLogger without testing being initialized.
Switch to a no-op logger instead.

Prior to #7177, these benchmarks did not provide any useful data about the
performance of the pubsub system (in fact, prior to #7178, half of them did not
work at all).

Specifically, they create a bunch of subscribers with 1 buffer slot on a
default publisher and copy messages to them. But because the publisher is
single-threaded, and doesn't block for delivery, all this tested is how long it
takes to receive a single message from a channel and deliver it to another
channel. The resulting stat does not even vary meaningfully with batch size,
since it's testing a serial workload.

Since #7177 the benchmarks do correctly reflect delivery time (good), but still
do not tell us anything useful: The latencies that matter for pubsub are not
internal queuing, but the effects of backpressure on the publisher via the
subscribers. That's an integration problem, and simulating a fake workload does
not provide meaningful results.

On that basis, remove these benchmarks.

I increased the chill of the github actions and NPM/docs dependencies,
and added default automerging of the go dependencies.

This ensures the implementation respects disabling the pex reactor.

Updates #7156, and a follow-up to #7070.

Event subscriptions in Tendermint currently use a fixed-length Go
channel as a queue. When the channel fills up, the publisher
immediately terminates the subscription. This prevents slow
subscribers from creating memory pressure on the node by not
servicing their queue fast enough.

Replace the buffered channel used to deliver events to buffered
subscribers with an explicit queue. The queue provides a soft
quota and burst credit mechanism: Clients that usually keep up
can survive occasional bursts, without allowing truly slow
clients to hog resources indefinitely.

Fixes #7176. Some of the benchmarks create a bunch of different subscriptions all sharing the same query. These were all using the same client ID, which violates one of the subscriber rules. Ensure each subscriber gets a unique ID.

This has been broken as long as this library has been in the repo—I tracked it back to bb9aa85d and it was already failing there, so I think this never really worked. I'm not sure these test anything useful, but at least now they run.
