Two things we need to do to fix build with OpenSSL 3.0:

1. Use EVP_MAC_* functions instead of HMAC_*
   https://www.openssl.org/docs/man3.0/man3/HMAC_CTX_new.html

2. Load the Legacy provider to enable legacy algorithms, such as MD4

We redefine ssl_init and ssl_free in the EE build, because we need to do
some extra work there. Currently, it's fine to duplicate the bulk of the
OpenSSL library initialization code between EE and CE repositories, but
with the introduction of OpenSSL 3.0 it's going to become more
complicated so duplicating would look bad. Let's move the common code to
ssl_init_impl() and ssl_free_impl() helper functions.

ERR_error_string adds some extra information that depends on the OpenSSL
library version (code, module, method). This information says nothing to
the end user, and it results in different test results after updating to
OpenSSL 3.0. Let's use ERR_reason_error_string instead, which just
prints a human-readable error message.

openssl_err_str is used for reporting OpenSSL errors. It calls
crypto_ERR_* functions using FFI. There's a typo in the code:
ffi.crypto_ERR_error_string is used instead of ffi.C.*.

We don't normally step on this, because OpenSSL doesn't return errors
in our configuration, but if it did for some reason (e.g. a cipher was
disabled in the library), we'd get a confusing error message.

Added 'tarantool/actions/cleanup' action to each job which uses
self-hosted runners.

The action cleans workspace directory of self-hosted runner after
previous run. The main reason to add this action is 'Need a single
revision' error [1] caused by a conflict of submodule versions,
the standard 'actions/checkout' action fails with this error. It's a
well-known problem and related issue [2] is still opened.

The inject remote method is used in testing quite a lot. For example,
when someone needs to pass arbitrary MsgPack to Tarantool.

The current way to use it is:
conn:_request(netbox._method.inject, opts, nil, nil, custom_msgpack)

This is quite long and ugly, so let's add a helper:
conn:_inject(custom_msgpack, opts)

Also, while we're at it, lets fix the following issue.
The _inject remote method is barely usable without knowing which sync
net.box will use for the next request.

On the one hand, the user has to encode some custom sync to the request
he's injecting.
On the other hand, net.box doesn't parse the custom sync and always uses
its own pre-generated one to wait for the request response.

So the user has to pick the correct sync value, which net.box uses
internally.

Let's make life simpler and introduce _next_sync method, which returns
the next sync, which will be used by net.box.

(cherry picked from commit 5893d61d)

A Tarantool server is supposed to send a greeting message right after
accepting a new client so the first thing an applier does after
connecting to the master is reads the greeting. It does this without
timeouts. The problem is that if by mistake we connect to a wrong
instance, which doesn't send anything to clients, the applier will hang
forever (until the remote closes the socket), without logging any
errors.

This may happen even with a valid Tarantool instance - if SSL encryption
is enabled on the master, but not on the client, because the SSL
protocol assumes that the client initiates a connection by writing to
the socket first (before the server).

Let's add a timeout to the operation reading the greeting. The timeout
is set to replication_disconnect_timeout(), after which a connection is
broken if the master doesn't send heartbeats for that long. Note, we
don't add a timeout to other read/write operations issued to initiate a
replication connection, because if we received a greeting and it's
valid, then the master is likely to be fine.

clang 13 includes a check for subtraction from NULL pointer which
is considered UB: historically, we had an alignment checking macro
which is affected by this. It seems like the intention of the
macro's author was to implicitly cast the pointer being checked to
uintptr_t without including stddef.h — replace this subtraction
with an explicit cast.

There is no way to set SQL_4_BYTE_ALIGNED_MALLOC, so the corresponding
part of the code was removed. Now there are only 8 byte alignment
assertions.

This client error assumes two arguments: space's name and index's name.
Since from the context it's clear that primary index is affected,
let's drop index name from error message. It's quite handy for space
upgrade case, since in such situation we have lack of information
concerning space.

We are going to utilize primary key definition during space upgrade in
order to verify primary key invariant. So we need it to be stored in
space_upgrade metadata. Let's extend space_upgrade_new() signature and
pass there primary key definition. Also patch moves space_upgrade_new()
call a bit lower through code - now it's called after all indexes are
assigned (to simplify extraction of primary key definition).
Moreover, in order to print pretty error message during space upgrade
we should keep space in struct space_upgrade.

We used to not implement comparison operators for interval
objects, thus any compare (even of equal) objects returned false:

	```
	tarantool> dt1 = datetime.new()
	---
	...

	tarantool> dt2 = datetime.now()
	---
	...

	tarantool> dt1 - dt1 == dt2 - dt2
	---
	- false
	...
	```

Now we implemented comparison for interval objects, where we compare
field by field starting from highest attribute (e.g. `year`) to
smallest attribute (e.g. `nsec`) and if any of comparison
returned non zero value then we return this result.

Use Olson/IANA tzdata for timezone handling in datetime string.

Closes of #6751

NO_TEST=doc

@TarantoolBot document
Title: Document timezone support

Timezones support
-----------------

Tarantool uses IANA tzdata aka Olson DB facilities for timezone
resolution at the moment of parsing of datetime literals or while
parsing `tz` attribute in constructor, or `:set{}` method call.

In addition to the `tzoffset` we provided before, we now define
`tzindex`, the unique index assigned by Tarantool to each known IANA
timezone.

```lua
date = require 'datetime'

tarantool> T = date.parse '2022-01-01T00:00 Europe/Moscow'

tarantool> T.tzindex
---
- 947
...

tarantool> T.tzoffset
---
- 180
...

tarantool> T.tz
---
- Europe/Moscow
...
```

Now `date.isdst` field (alone and as part of `:totable()` table) is
correctly calculated using `tzindex` and attributes of the selected
timezone in the Olson DB timezone.

```
tarantool> date.parse('2004-06-01T00:00 Europe/Moscow').isdst
---
- true
...

tarantool> date.parse('2004-12-01T00:00 Europe/Moscow'):totable()
---
- sec: 0
  min: 0
  yday: 336
  day: 1
  nsec: 0
  isdst: false
  wday: 4
  tzoffset: 180
  month: 12
  year: 2004
  hour: 0
...

```

All timezone names and abbreviations, known to the current Tarantool
version are available via `datetime.TZ` bidirectional array.

```lua
print(date.TZ['Europe/Moscow']) -- 947
print(date.TZ[947]) -- Europe/Moscow
```

Limitations
-----------

There were moments in past history, when local mean time in some
partcular zone used timezone offset not representable in whole
minutes, but rather in seconds, i.e. in Moscow before 1918 there
used to be offset +2 hours 31 minutes and 19 seconds. Please see
Olson dump for this period

```
$ ./src/lib/tzcode/install/usr/bin/zdump -c1880,1918 -i Europe/Moscow

TZ="Europe/Moscow"
-       -       +023017 MMT
1916-07-03      00:01:02        +023119 MMT
1917-07-02      00      +033119 MST     1
1917-12-27      23      +023119 MMT
```

Modern tzdata rules do not use such tiny fraction, and all timezones differ
to UTC in units measured in minutes, not seconds. Tarantool datetime uses
minutes internally as units for `tzoffset` so there is some loss of
precision if you try to operate with such ancient timestamps.

A certificate used for an encrypted replication connection may expire,
in which case the user will be forced to reconfigure the connection both
on the master and on the replica to use the new certificate. If the
replica completes the reconfiguration first, it will fail to connect to
the master and never retry, even though the master should complete its
reconfiguration in a moment.

To avoid that, we should make the applier retry to connect on SSLError,
just like it does on SocketError.

Applier uses box_error_code() to for better logging:
 - It remembers tha last raised error code and skips logging if the new
   error code is the same.
 - It logs "will retry every X seconds" only for retryable error codes
   (for example, ER_SYSTEM) while for non-retryable errors (for example,
   ER_PROC_LUA) the message isn't logged.

box_error_code() returns ER_PROC_LUA for SSLError, which is confusing
and would result in inconsistent logging in applier if we made SSLError
retryable. Let's add a separate error code for this error (ER_SSL) and
introduce a test case that checks that box_error_code() works as
expected for all kinds of errors.

This patch introduces operator [] that allows to get elements from MAP
and ARRAY values.

Closes #4762
Closes #4763
Part of #6251

@TarantoolBot document
Title: Operator [] in SQL

Operator `[]` allows to get an element of MAP and ARRAY values.
Examples:
```
tarantool> box.execute([[SELECT [1, 2, 3, 4, 5][3];]])
---
- metadata:
  - name: COLUMN_1
    type: any
  rows:
  - [3]
...

tarantool> box.execute([[SELECT {'a' : 123, 7: 'asd'}['a'];]])
---
- metadata:
  - name: COLUMN_1
    type: any
  rows:
  - [123]
...
```

The returned values is of type ANY.

If the operator is applied to a value that is not a MAP or ARRAY or is
NULL, an error is thrown.

Example:
```
tarantool> box.execute([[SELECT 1[1];]])
---
- null
- Selecting is only possible from map and array values
...
```

However, if there are two or more operators next to each other, the
second or following operators do not throw an error, but instead
return NULL.

Example:
```
tarantool> box.execute([[select [1][1][2][3][4];]])
---
- metadata:
  - name: COLUMN_1
    type: any
  rows:
  - [null]
