BLPOP when there are elements in the list works in the same way as LPOP
does. Due to this they also does the same repetitive action and logic
for the same is written at two different places. This is a bad code
practice as the one needs the context to change the BLPOP list pop code
as well when the LPOP code gets changed.
Separated the generic logic from LPOP to a function that is being used
by the BLPOP code as well.

Test support for the new map, null and push message types. Map objects are parsed as a list of lists of key value pairs.
for instance: user => john password => 123
will be parsed to the following TCL list:
{{user john} {password 123}}
Also added the following tests:
Redirection still works with RESP3
Able to use a RESP3 client as a redirection client
No duplicate invalidation messages when turning BCAST mode on after normal tracking
Server is able to evacuate enough keys when num of keys surpasses limit by more than defined initial effort
Different clients using different protocols can track the same key
OPTOUT tests
OPTIN tests
Clients can redirect to the same connection
tracking-redir-broken test
HELLO 3 checks
Invalidation messages still work when using RESP3, with and without redirection
Switching to RESP3 doesn't disturb previous tracked keys
Tracking info is correct
Flushall and flushdb produce invalidation messages
These tests achieve 100% line coverage for tracking.c using lcov.

* provide getRangeLongFromObjectOrReply and getPositiveLongFromObjectOrReply for range check

Expose new `loading_rdb_used_mem` showing the used memory of the server
that saved the RDB file we're currently using.
This is useful in diskless replication when the total size of the rdb is
unkown, and can be used as a rought estimation of progres.
Use that new field to calculate the "user friendly"
`loading_loaded_perc` and `loading_eta_seconds`.
Expose `master_sync_total_bytes` and `master_sync_total_bytes` to complement
on the existing `master_sync_total_bytes` (which cannot be used on its own
to calculate progress).
Add "user friendly" field for `master_sync_perc`

Perform full reset of all client connection states, is if the client was
disconnected and re-connected. This affects:
* MULTI state
* Watched keys
* MONITOR mode
* Pub/Sub subscription
* ACL/Authenticated state
* Client tracking state
* Cluster read-only/asking state
* RESP version (reset to 2)
* Selected database
* CLIENT REPLY state
The response is +RESET to make it easily distinguishable from other
responses.

Not disabling save, slower systems begun background save that did not
complete in time, resulting with SAVE failing with "ERR Background save

- rdbSaveSingleModuleAux() used RedisModuleIO's "bytes" field for
tracking written bytes before calling moduleInitIOContext() which sets
"bytes" to zero
- rdbSaveObject() re-initialized RedisModuleIO too late
This return value is not used at the moment since it's only tested
against -1, and the actual byte count isn't used yet.

This will allow to use: RedisModule_CreateStringPrintf(ctx, "%s %c %s", "string1", 0, "string2");
On large string, the previous code would incrementally retry to double the output buffer.
now it uses the the return value of snprintf and grows to the right size in one step.
and also avoids an excessive strlen in sdscat at the end.
