Our test cases spew a lot of files and directories around $TMPDIR.  Make more
thorough use of the testing package's TempDir methods to ensure these are
cleaned up.

In a few cases, this required plumbing test contexts through existing helper
code. In a couple places an explicit path was required, to work around cases
where we do global setup during a TestMain function. Those cases probably
deserve more thorough cleansing (preferably with fire), but for now I have just
worked around it to keep focused on the cleanup.

This pull request merges in the changes for implementing Proposer-based timestamps into `master`. The power was primarily being done in the `wb/proposer-based-timestamps` branch, with changes being merged into that branch during development. This pull request represents an amalgamation of the changes made into that development branch. All of the changes that were placed into that branch have been cleanly rebased on top of the latest `master`. The changes compile and the tests pass insofar as our tests in general pass.

### Note To Reviewers
 These changes have been extensively reviewed during development. There is not much new here. In the interest of making effective use of time, I would recommend against trying to perform a complete audit of the changes presented and instead examine for mistakes that may have occurred during the process of rebasing the changes. I gave the complete change set a first pass for any issues, but additional eyes would be very appreciated. 

In sum, this change set does the following:
closes #6942 
merges in #6849

*light: rpc /status returns status of light client ; code refactoring
 light: moved lightClientInfo into light.go, renamed String to ID
test/e2e: Return light client trusted height instead of SyncInfo trusted height
test/e2e/start.go: Not waiting for light client to catch up in tests. Removed querying of syncInfo in start if the node is a light node

* light: Removed call to primary /status. Added trustedPeriod to light info
* light/provider: added ID function to return IP of primary and witnesses
* light/provider/http/http_test: renamed String() to ID()

This change has two main effects:

1. Remove most of the Async methods from the abci.Client interface.
   Remaining are FlushAsync, CommitTxAsync, and DeliverTxAsync.

2. Rename the synchronous methods to remove the "Sync" suffix.

The rest of the change is updating the implementations, subsets, and mocks of
the interface, along with the call sites that point to them.

* Fix stringly-typed mock stubs.
* Rename helper method.

The custom error types in the provider package did not propagate their wrapped
underlying reasons, making it difficult for the test to check that the correct
error was observed.

- Fix the custom errors to have a true underlying error (not just a string).
- Add Unwrap methods to support inspection by errors.Is.
- Update usage in a few places.
- Fix the test to check for acceptable variation.

Fixes #7609.

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.

This is, perhaps, the trival final piece of #7075 that I've been
working on.

There's more work to be done: 
- push more of the setup into the pacakges themselves
- move channel-based sending/filtering out of the 
- simplify the buffering throuhgout the p2p stack.

This is another small sliver of #7075, with the intention of removing
the legacy shim layer related to channel registration.

Few things that had been annoying.

This is mostly just reading through the output of uparam, after
noticing that there were a few places where we were ignoring some arguments.

This is intended to fix a test failure that occurs in the p2p state provider. The issue presents as the state provider timing out waiting for the consensus params response. 

The reason that this can occur is because the statesync reactor has the possibility of attempting to respond to the params request before the state provider is ready to read it. This results in the reactor hitting the `default` case seen here and then never sending on the channel. The stateprovider will then block waiting for a response and never receive one because the reactor opted not to send it.

When statesync is stopped during shutdown, it has the possibility of deadlocking. A dump of goroutines reveals that this is related to the peerUpdates channel not returning anything on its `Done()` channel when `OnStop` is called. As this is occuring, `processPeerUpdate` is attempting to acquire the reactor lock. It appears that this lock can never be acquired. I looked for the places where the lock may remain locked accidentally and cleaned them up in hopes to eradicate the issue. Dumps of the relevant goroutines may be found below. Note that the line numbers below are relative to the code in the `v0.35.0-rc1` tag.

This test reliably gets hung up on network configuration, (which may
be a real issue,) but it's network setup is handcranked and we should
ensure that the test focuses on it's core assertions and doesn't fail for 
test architecture reasons.

I've been noticing that there are a number of situations where the
statesync reactor blocks waiting for peers (or similar,) I've moved
things around to improve outcomes in local tests.

The code in the Tendermint repository makes heavy use of import aliasing.
This is made necessary by our extensive reuse of common base package names, and
by repetition of similar names across different subdirectories.

Unfortunately we have not been very consistent about which packages we alias in
various circumstances, and the aliases we use vary. In the spirit of the advice
in the style guide and https://github.com/golang/go/wiki/CodeReviewComments#imports,
his change makes an effort to clean up and normalize import aliasing.

This change makes no API or behavioral changes. It is a pure cleanup intended
o help make the code more readable to developers (including myself) trying to
understand what is being imported where.

Only unexported names have been modified, and the changes were generated and
applied mechanically with gofmt -r and comby, respecting the lexical and
syntactic rules of Go.  Even so, I did not fix every inconsistency. Where the
changes would be too disruptive, I left it alone.

The principles I followed in this cleanup are:

- Remove aliases that restate the package name.
- Remove aliases where the base package name is unambiguous.
- Move overly-terse abbreviations from the import to the usage site.
- Fix lexical issues (remove underscores, remove capitalization).
- Fix import groupings to more closely match the style guide.
- Group blank (side-effecting) imports and ensure they are commented.
- Add aliases to multiple imports with the same base package name.

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.
