kafka/tx: explicitly fail txs on the compacted topics
8214f28 
We had an issue when an upcall from the storage layer to the transactional layer
caused an deadlock.

See https://vectorizedio.slack.com/archives/C01QNK06XDW/p1627640921011100

It's likely was caused by issues fixed by:

  - "kafka/tx: fix stalls on truncation"
  - "cluster: fix hanging persisted_stm::sync"

But since we don't fully support transactions for the compacted topics it's
safer to remove the (so far) unnecessary upcalls from the storage layer and
to explicitly fail transactional requests attemping to modify the compacted

tools: do addr2lines conversion on unit test failure output
911b3c4 
The downside of this is that we're going to output all
stderr output in one go at the end, rather than it being
roughly interleaved with stdout output.

kafka/tx: do not create rm_stm for int. topics
3b67249 
redpanda/coordinator is a special topic which is managed by its own
state machine. Since it doesn't use transactional processing it's
safer not to initiate rm_stm to avoid unnecessary risk.

The same is true for kafka_internal/group. Although we don't use an
explicit state machine (a derived class from state_machine) we use
a similar pattern:

 - contolling a access to the log via a resticted API
 - replaying a log to reconstruct state
 - using this state when processing consumer group requests

kafka/tx: switch tx coordinator to deletion policy
d23856e 
Transactions don't support compaction at 100% (see ch2968). Updating
disk_log_impl to let tx coordinator use deletion clean up policy.

kafka/tx: make tx coordinator use correct err codes
0ad8730 
Switching to the correct error codes (aligned the spec) helps with performance
and client comparability.

@rystsov
kafka/tx: automatically abort inactive transactions
4763d6a 
Previous iteration of the auto aborting logic could miss an inactive
transaction.. It used to happen when a tx coordinator restarted before
saving a tx's status and when data partition restarted after saving a
transactional batch.
@rystsov
kafka/tx: support invalid_txn_state error code
deea37a 
Redpanda protocol depends either on calling abortTransactions on a failure
during adding a partition to a transaction

    try {
        producer.beginTransaction();
        producer.send(...);
        producer.send(...);
        producer.commitTransaction();
    } catch (KafkaException e) {
        producer.abortTransaction()
    }

or closing and recreating a producer.

It happen that Kafka client doesn't always send end_txn RPC to a server
when .abortTransaction() is invoked.

See https://issues.apache.org/jira/browse/KAFKA-5260

By returning INVALID_TXN_STATE we'll force a user to close and recreate
a producer.

persisted_stm: make ::start more lightweight
985857b 
Taking a snapshot on a start up is premature optimization, we anyway do
it when we roll segments so it's safer to do less things when Redpanda
isn't fully initialized.

For example, for nodejs we need set of active scrtips_ids,
for data-policy we need map from script_id to code of js script
