Temporary spaces, used for cluster-wide SQL data materialization,
were causing unnecessary netbox schema version bumps, leading to
schema downloading via netbox, excessive Lua garbage and GC blocks.
Since these tables are for internal SQL use, we don't need to inform
netbox clients about schema changes. We now maintain separate schema
versions: one for netbox clients and one for the internal prepared
statement cache.

CentOS 7 reached its end-of-life on 30/06/2024, making its
repositories unavailable. Therefore, continuing to build CI
images for it is no longer sensible. We have now switched to
Rocky Linux 8.

BREAKING CHANGE!:
1. remove sql_prepare from the export list;
2. introduce sql_prepare_ext.

The sql_prepare symbol previously included the tarantool port as
an output parameter. However, this structure was inconvenient for
libraries using the C API, as they primarily required just the
statement ID. To address this issue, the sql_prepare symbol was
replaced with the sql_prepare_ext symbol.

Previously, users with multiple connections to tarantool instance
couldn't share prepared statements across sessions. They had to
manually call prepare in each session before execution.

This commit automates this process for the exported version of
SQL prepared statement execution (sql_execute_prepared_ext symbol).
Original Lua execution keeps the old behavior for backward
compatibility.

Previously, sql_prepare_and_execute and sql_execute_prepared
functions didn't follow a convention to keep output parameters
(the port to be exact) at the end of the argument list.

BREAKING CHANGE!:
1. sql_bind_list_decode - removed
2. sql_execute_prepared_ext - new arguments
3. sql_prepare_and_execute_ext - exported

There were several reasons to refactor the API.
1. sql_bind_list_decode (decodes message pack parameters into
   internal C bind structure) is very difficult to use without
   memory leaks (as it allocates results on fiber()->gc).
2. sql_execute_prepared_ext missed vdbe step limit in parameters
   and used the default value.
3. Sometimes SQL queries don't fit into prepared statement cache
   and the user still wants to execute them via a slow pass with
   full compilations from the query text. That was the reason to
   export sql_prepare_and_execute_ext symbol.

The following commit introduced a tautological if expression:

```gitcommit
sql: introduce structs assembling DDL arguments during parsing (ba56b145fafaa3)
```

Due to the changes in commit

```gitcommit
sql: refactor memory allocation system (cb777136dd7a0c)
```

the allocations in sql expressions became infallible, which means
that we may safely fix static analysis warnings by dropping the
tautological comparison altogether.

Add new transport for IPROTO connections: ssl.
SSL transport may be configured with (at client and server side):
- certificate (mandatory at server side)
- private key (mandatory at server side)
- password for PK
- certificate authorities (for peer certificate verification)
- cipher list

SSL transport also can be used in replication and net.box mechanisms.

@TarantoolBot document
Title: add IPROTO traffic encryption.

New ssl transport allows
creating a secure connection between two IPROTO peers.
TLS protocol using and openssl v1.1 or later required.

To configure traffic encryption, you need to set the
special URI parameters for a particular connection.
The parameters can be set for the following box.cfg
options and nex.box method:
- box.cfg.listen – on the server side.
- box.cfg.replication–on the client side.
- net_box_object.connect()–on the client side.

Currently, DDL transaction may abort other in-progress
transactions (this behavior added in #8f4be322 - avoid sharing
(ergo phantom reads) metadata object for different
transactions in MVCC mode).
This behavior makes no sense if the MVCC is
disabled (cause these conflicts never happen).

Closes #47
