* Work around API changes in the migrator package.
A recent update inadvertently broke the API by changing the receiver types of
the methods without updating the constructor.

Noticed in profiles that invoking *VoteSignBytes always created a
bytes.Buffer, then discarded it inside protoio.MarshalDelimited.
I dug further and examined the call paths and noticed that we
unconditionally create the bytes.Buffer, even though we might
have proto messages (in the common case) that implement
MarshalTo([]byte), and invoked varintWriter. Instead by inlining
this case, we skip a bunch of allocations and CPU cycles,
which then reflects properly on all calling functions. Here
are the benchmark results:
```shell
$ benchstat before.txt after.txt

Thanks to Tharsis who tasked me to help them increase TPS and who
are keen on improving Tendermint and efficiency.

This continues the push of plumbing contexts through tendermint. I
attempted to find all goroutines in the production code (non-test) and
made sure that these threads would exit when their contexts were
canceled, and I believe this PR does that.
Some of our tests were creating a psql event sink and expecting
it to report (or not report) certain kinds of errors. These tests
were ill-founded in a couple of ways:
1. Tests that required the Postgres driver were not loading it.
This led to spurious successes on tests that wanted "some error"
from the sink constructor, but didn't exercise the right path.
2. Tests that wanted a Postgres sink to succeed without a database.
These tests "passed" because they weren't actually establishing a
connection to the database, but if they had would have failed for
the lack of one.
To fix this:
- Load the postgres driver in tests that need it.
- Verify connectivity before reporting successful creation of a PSQL event sink.
- Remove tests that wanted a psql sink without a database, since that case
is already tested elsewhere.
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.
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.
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.
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.
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.
