* Rename rpctypes.Context to CallInfo.

Add methods to attach and recover this value from a context.Context.

* Rework RPC method handlers to accept "real" contexts.

- Replace *rpctypes.Context arguments with context.Context.
- Update usage of RPC context fields to use CallInfo.

Where possible, replace uses of the custom JSON library with the standard
library. The custom library treats interface and unnamed lteral types
differently, so this change avoids those even where it would probably be safe
to switch them.

No API changes, merely changes the import path.

Inline the one usage of this library, and remove the lib.

* 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.

The test service was starting up without a logger and crashing
while trying to log.

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:

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.

I saw a race detected in a test here that I think would be better
handled by just wiring up these threads.

* eventbus: plumb contexts

* fix lint

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.
