Update the schema and implementation of the Postgres event indexer to improve 
certain types of queries against the index. These changes address the use cases
raised by #6843, and are partly inspired by the prototype schema in that issue.

In the old schema, events were flattened, making it difficult to find all the events 
associated with a particular block or transaction. In addition, events with no key/value
attributes were entirely lost, since entries were generated only for attributes.

To address these issues, this new schema records blocks, transactions, events,
and attributes in separate tables, and provides views that join these tables to
give a more convenient query surface for block and transaction events.

- All events for a given block can be queried from the `block_events` view.
- All events for a given transaction can be queried from the `tx_events` view.
- Multiple events for the same key can be indexed for both blocks and transactions.

The tests have been reworked, but all of the existing test cases for the old schema 
still pass with the new implementation. Various other minor cleanups are included,

ADR-065 is also updated to reflect the updated schema.

Add documentation comments to the psql event sink package, and simplify the
constructor function so that it does not return the SQL database handle.  The
handle is needed for testing, so expose that via a separate method on the
concrete type.

Update the tests and existing usage for the change. This change does not affect
the behaviour of the sink, so there are no functional changes, only syntactic
updates.

EDIT: Updated, see [comment below]( https://github.com/tendermint/tendermint/pull/6785#issuecomment-897793175)

This change adds a sketch of the `Debug` mode. 

This change adds a `Debug` struct to the node package. This `Debug` struct is intended to be created and started by a command in the `cmd` directory. The `Debug` struct runs the RPC server on the data directories: both the state store and the block store.

This change required a good deal of refactoring. Namely, a new `rpc.go` file was added to the `node` package. This file encapsulates functions for starting RPC servers used by nodes. A potential additional change is to further factor this code into shared code _in_ the `rpc` package. 

Minor API tweaks were also made that seemed appropriate such as the mechanism for fetching routes from the `rpc/core` package.

Additional work is required to register the `Debug` service as a command in the `cmd` directory but I am looking for feedback on if this direction seems appropriate before diving much further.

closes: #5908

This is a very minor change, but I was looking through the code, and
this seems like it shouldn't be exported or used more broadly, so I've
moved it out.

This change aims to keep versions of mockery consistent across developer laptops.

This change adds mockery to the `tools.go` file so that its version can be managed consistently in the `go.mod` file.

Additionally, this change temporarily disables adding mockery's version number to generated files. There is an outstanding issue against the mockery project related to the version string behavior when running from `go get`. I have created a pull request to fix this issue in the mockery project.
see: https://github.com/vektra/mockery/issues/397

Update those break statements inside case clauses that are intended to reach an
enclosing for loop, so that they correctly exit the loop.

The candidate files for this change were located using:

    % staticcheck -checks SA4011 ./... | cut -d: -f-2

This change is intended to preserve the intended semantics of the code, but
since the code as-written did not have its intended effect, some behaviour may
change. Specifically: Some loops may have run longer than they were supposed
to, prior to this change.

In one case I was not able to clearly determine the intended outcome. That case
has been commented but otherwise left as-written.

Fixes #6780.

This is a mostly-automated fixup using Comby (https://comby.dev) to remove 
lexically-obvious redundant error checks. No functional changes are intended.

To reproduce the core change:

    # Collapse redundant error check conditionals
    % comby -in-place 'if err != nil {
       return err
    }
    return nil' 'return err' .go

    # Fold out unnecessary error temporaries
    % comby -in-place ':[spc~^\s*]err :[~:?]= :[any]
       return err' ':[spc]return :[any]' .go

Fixes #6479 and related cases.

There are many `//go:generate mockery` lines in the source code.
This change adds a make target to invoke these mock generations.
This change also invokes the mock invocations and adds the resulting mocks to the repo.
