* chore: add active time to stream consumers
Adjust XINFO command to output active-time property.
Store active-time and switch to RDB_TYPE_STREAM_LISTPACKS_3 if FLAGS_stream_rdb_encode_v2
is enabled.

Now rdb_load supports RDB_TYPE_STREAM_LISTPACKS, RDB_TYPE_STREAM_LISTPACKS_2 and RDB_TYPE_STREAM_LISTPACKS_3 formats.
rdb_save still saves with RDB_TYPE_STREAM_LISTPACKS format - we want to release the DF version that can load everything first, and
then update the replicaion format in the next versions.
Also, update rdb_test.cc

* chore: let resp parser provide more useful logs
1. More warning logs around bad BAD_ARRAYLEN messages
2. Lift the restriction around big bulk strings and log a warning instead.
3. Pull helio

* chore: Fix `test_rss_used_mem_gap` for all types
The test fails when it checks the gap between `used_memory` and
`object_used_memory`, by assuming that all used memory is consumed by
the `type` it `DEBUG POPULATE`s with.
This assumption is wrong, because there are other overheads, for example
the dash table and string keys.
The test failed for types `STRING` and `LIST` because they used a larger
number of keys as part of the test parameters, which added a larger
overhead.
I fixed the parameters such that all types use the same number of keys,
and also the same number of elements, modifying only the element sizes
(except for `STRING` which doesn't have sub-elements) so that the
overall `min_rss` requirement of 3.5gb still passes.
Fixes#3723
* threshold
* list
* comments test assert
* previous numbers
* ???
We have cascading failures in cluster tests because on assertion failures the nodes are not properly cleaned up and subsequent test cases that use the same ports fail. I added a monotonically increasing port generator to mitigate this effect.
* remove DbSlice mutex
* add ConditionFlag in SliceSnapshot
* disable compression when big value serialization is on
* add metrics

The bug:
calling lua_error does not return, instead it unwinds the Lua call stack until an error handler is found or the
script exits. This lead to memory leak on object that should release memory in destructor.
Specific example is the absl::FixedArray<string_view, 4> args(argc); which allocates on heap if argc > 4. The free was not called leading to memory leak.
The fix:
Add scoping to to the function so that the destructor is called before calling raise error

This PR syncs some of the improvements that were introduced in streams in Redis 7.2.3 OSS.
1. verify xsetid against max deleted id in the stream
2. Implement precise memory measurement of streams for "memory usage" command.
3. Always compact nodes in stream listpacks after creating new nodes.

Specifically:
* `INFO REPLICATION` does not list the replicas, but does still show
`connected_slaves`
* `INFO SERVER` does not show `thread_count` and `os`
Fixes#4173
There are actually a few failures fixed in this PR, only one of which is a test bug:
* `db_slice_->Traverse()` can yield, causing `fiber_cancelled_`'s value to change
* When a migration is cancelled, it may never finish `WaitForInflightToComplete()` because it has `in_flight_bytes_` that will never reach destination due to the cancellation
* `IterateMap()` with numeric key/values overrode the key's buffer with the value's buffer
Fixes#4207
* fix: bugs in stream code
1. Memory leak in streamGetEdgeID
2. Addresses CVE-2022-31144
3. Fixes XAUTOCLAIM bugs and adds tests.
4. Limits the count argument in XAUTOCLAIM command to 2^18 (CVE-2022-35951)
Also fixes#3830

1. Use transaction time in streams code, similarly to how we do it in other commands.
Stop using mstime() and delete unused redis code.
2. Check for sequence overflow issue when passing huge sequence ids.
Add a test.
