* p2p: reduce peer score for dial failures (#7265)
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 ensures the implementation respects disabling the pex reactor.

Fixes#7176. Some of the benchmarks create a bunch of different subscriptions all sharing the same query. These were all using the same client ID, which violates one of the subscriber rules. Ensure each subscriber gets a unique ID.
This has been broken as long as this library has been in the repo—I tracked it back to bb9aa85d and it was already failing there, so I think this never really worked. I'm not sure these test anything useful, but at least now they run.

* p2p: add message type into the send/recv bytes metrics (#7155)
This pull request adds a new "mesage_type" label to the send/recv bytes metrics calculated in the p2p code.

This pull request fixes a panic that exists in both mempools. The panic occurs when the ABCI client misses a response from the ABCI application. This happen when the ABCI client drops the request as a result of a full client queue. The fix here was to loop through the ordered list of recheck-tx in the callback until one matches the currently observed recheck request.

Fixes#7068. The build-docker rule relies on being able to run make
build-linux, but did not pull the Makefile into the build context.
There are various ways to fix this, but this was probably the smallest.

Fixes#7098. The light client documentation moved to the spec repository.
I was not able to figure out what happened to light-client-protocol.md, it was removed in #5252 but no corresponding file exists in the spec repository. Since the spec also discusses the protocol, this change simply links to the spec and removes the non-functional reference.
Alternatively we could link to the top-level [light client doc](https://docs.tendermint.com/master/tendermint-core/light-client.html) if you think that's better.

It seems weird in retrospect that we allow networks to contain
applications that use different ABCI protocols.

Addresses one of the concerns with #7041.
Provides a mechanism (via the RPC interface) to delete a single transaction, described by its hash, from the mempool. The method returns an error if the transaction cannot be found. Once the transaction is removed it remains in the cache and cannot be resubmitted until the cache is cleared or it expires from the cache.

This PR tackles the case of using the e2e application in a long lived testnet. The application continually saves snapshots (usually every 100 blocks) which after a while bloats the size of the application. This PR prunes older snapshots so that only the most recent 10 snapshots remain.

The race occurred as a result of a goroutine launched by `processPeerUpdate` racing with the `OnStop` method. The `processPeerUpdates` goroutine deletes from the map as `OnStop` is reading from it. This change updates the `OnStop` method to wait for the peer updates channel to be done before closing the peers. It also copies the map contents to a new map so that it will not conflict with the view of the map that the goroutine created in `processPeerUpdate` sees.
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.

When shutting down blocksync, it is observed that the process can hang completely. A dump of running goroutines reveals that this is due to goroutines not listening on the correct shutdown signal. Namely, the `poolRoutine` goroutine does not wait on `pool.Quit`. The `poolRoutine` does not receive any other shutdown signal during `OnStop` becuase it must stop before the `r.closeCh` is closed. Currently the `poolRoutine` listens in the `closeCh` which will not close until the `poolRoutine` stops and calls `poolWG.Done()`.
This change also puts the `requestRoutine()` in the `OnStart` method to make it more visible since it does not rely on anything that is spawned in the `poolRoutine`.

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.
Fix the order of lines in docs/versions so that v0.34 is last (the current release).
Related changes:
