Don't set nil config when seeding topics in kfake cluster #826

Setting the configs to nil causes it to panic later when trying to alter the topic configs, as it only checks for entry in the map not being present, not for it not being nil.

I don't see any tests here, I'd be happy to add one, but then I'd have to import kgo and kadm from kfake, is that ok?

Looks good, sorry I missed this. No tag necessary since kfake is not tagged yet. Tests eh............. we'll leave that question for later (kfake is largely used for tests at the moment)

* kgo: fix potential deadlock when reaching max buffered (records|bytes)

Problem:
* Record A exceeds max, is on path to block
* Record B finishes concurrently
* Record A's context cancels
* Record A's goroutine waiting to be unblocked returns, leaves accounting mutex in locked state
* Record A's select statement chooses context-canceled case, trying to grab the accounting mutex lock

See twmb#831 for more details.

Closes twmb#831.

* all: unlint what is now cropping up

gosec ones are delibate; govet ones are now randomly showing up (and
also deliberate)

kgo: fix potential deadlock when reaching max buffered (records|bytes)

* kgo: misc doc update

* kgo: ignore OOOSN where possible

See embedded comment. This preceeds handling KIP-890.

Closes twmb#805.

* kip-890 definitions

A bunch of version bumps to indicate TransactionAbortable is supported
as an error return.

* kip-848 more definitions

Added in Kafka 3.8:
* ListGroups.TypesFilter
* ConsumerGroupDescribe request

* kip-994 proto

Only ListTransactions was modified in 3.8

* sr: add StatusCode to ResponseError, and message if the body is empty

Closes twmb#819.

* generate / kmsg: update GroupMetadata{Key,Value}

Not much changed here.

Closes twmb#804.

* kgo: do not add all topics to internal tps map when regex consuming

The internal tps map is meant to be what we store topicPartitions in
that we are candidates to be consumed. This is filtered in
assignPartitions to only opt-in partitions that are actually being
consumed.

It's not BAD if we store all topics in that map, but it's not the
intent. The rest of the client worked fine even with extra topics in the
map.

When regex consuming, the metadata function previously put all topics
into the map always. Now, we move the regex evaluation logic --
duplicated in both the direct and group consumers -- into one function
and use that for filtering within metadata.

This introduces a required sequence of filtering THEN finding
assignments, which is fine / was the way things operated anyway.

Moving the filtering to metadata (only in the regex consuming logic)
means that we no longer store information for topics we are not
consuming. Indirectly, this fixes a bug where `GetConsumeTopics` would
always return ALL topics when regex consuming, because
`GetConsumeTopics` always just returned what was in the `tps` field.

This adds a test for the fixed behavior, as well as tests that NOT regex
consuming always returns all topics the user is interested in.

Closes twmb#810.

Proto 3.8.0

* kgo: support Kafka 3.8's kip-890 modifications

STILL NOT ALL OF KIP-890, despite what I originally coded.
Kafka 3.8 only added support for TransactionAbortable.
Producers still need to send AddPartitionsToTxn.

* kversion: note kip-848 additions for kafka 3.8

* kversion: note kip-994 added in 3.8, finalize 3.8

* kversion: ignore API keys 74,75 when guessing versions

These are in Kraft only, and are two requests from two separate KIPs
that aren't fully supported yet. Not sure why only these two were
stabilized.

* README: note 3.8 KIPs

* kgo: bump kmsg pinned dep
