Was tendermint/tendermint#9428

The primary focus of the v0.38 release will be rolling out ABCI++ vote extensions and FinalizeBlock functionality.

Deprioritised from this release:

  • Operators should have more control over bandwidth consumption
    • Investigate where Tendermint bandwidth is being consumed (perhaps capture this in an RFC as an articulation of the problem space)
    • Find short-term wins/low-hanging fruit where bandwidth consumption can be reduced (ideally in Q4 of 2022)
  • Monitoring/logging improvements #54

Closing since v0.38 is out.

Investigate where Tendermint bandwidth is being consumed (perhaps capture this in an RFC as an articulation of the problem space)

* perf(libs/json): Lower heap overhead of JSON encoding (backport cometbft#2846) (cometbft#2876)

---

Many RPC methods require JSON marshalled responses. We saw this taking a
notable amount of heap allocation in query serving full nodes. This PR
removes some extra heap allocations that were being done. We avoided
using the more efficient encoder.Encode before, because it added a
newline. This PR changes the function signature for these private
methods to be using *bytes.Buffer, and then uses the in-buffer methods
(rather than a second copy). We then just truncate the final byte after
each such call, which does not waste any allocations.

I added a benchmark for the most complex test case.

OLD:
```
BenchmarkJsonMarshalStruct-12              78992             15542 ns/op            4487 B/op        191 allocs/op
```
New:
```
BenchmarkJsonMarshalStruct-12              93346             11132 ns/op            3245 B/op         58 allocs/op
```

Roughly a 3-4x reduction in the number of allocations, and 20% speedup.
