When implementing the code that saves and loads these aux fields we used rdb
format that was added for that in redis 5.0, but then we added the 'when' field
which meant that the old redis-check-rdb won't be able to skip these.
this fix adds an opcode as if that 'when' is part of the module data.

Before this commit we may have not consumer buffers when a read error is
encountered. Such buffers may contain errors that are important clues
for the user: for instance a protocol error in the payload we send in
pipe mode will cause the server to abort the connection. If the user
does not get the protocol error, debugging what is happening can be a
nightmare.
This commit fixes issue #3756.
CLIENT PAUSE may be used, in other contexts, for a long time making all
the slaves time out. Better for now to be more specific about what
should disable senidng PINGs.
An alternative to that would be to virtually refresh the slave
interactions when clients are paused, however for now I went for this
more conservative solution.
In fast systems "SLOWLOG RESET" is fast enough to don't be logged even
when the time limit is "1" sometimes. Leading to false positives such
as:
[err]: SLOWLOG - can be disabled in tests/unit/slowlog.tcl
Expected '1' to be equal to '0'
solving few replication related tests race conditions which fail on slow machines
bugfix in slave buffers test: since the test is executed twice, each time with
a different commands count, the threshold for the delta can't be a constant.
A filter handle is returned and can be used to unregister a filter. In
the future it can also be used to further configure or manipulate the
filter.
Filters are now automatically unregistered when a module unloads.
Hi, @antirez
In the code, to get the size of ziplist, "unsigned int bytes = ZIPLIST_HEADER_SIZE+1;" is correct,
but why not make it more readable and easy to understand
