It's impossible to set names on Tarantool below 3.0.0, as all DDL
is forbidden before schema upgrade.

Let's make names NoOp on schema below Tarantool 3.0.0 and set names
automatically only when schema upgrade is done.

Follow-up #8978

NO_DOC=tarantool/doc#3661

This commit moves all code, related to working with versions and which
was used in box/lua/upgrade.lua, into a separate module and exports it
to Lua API as 'internal.version'

This is needed, as in the following commit we set names automatically
only when schema version is more than 3.0.0. This module is used their
in order to avoid code duplication.

For now it's impossible to use config module in order to recover
from snaps, which don't have names set in them. Calling box.cfg
with names on recovery fails with MISMATCH error, which is caused
by difficult implementation of setting names on first box.cfg,
as names can be set only on rw instance.

This commit doesn't call box.cfg with names, if these names are
missing from the snapshot file. Instead it creates a fiber, which
will set names, when it's possible to do so. Only master sets the
names for the whole cluster.

Closes #8978

NO_DOC=tarantool/doc#3661
NO_CHANGELOG=following commits

When the name is manually set on master by replace in _cluster space,
calling box.cfg on replica with the same name causes its hang. The
problem is the fact, that resubscribe is initiated and waiting for
APPLIER_REGISTERED status is started. As applier knows, that no
registration should be done, this never happens.

Let's don't initiate registration, when instance name is already set.

For now it's impossible to drop created alert in any way except
manual searching for _alerts table. However, we need to drop alerts
on missing names, when the names are set.

Let's introduce simple key-value alerts in order to easily drop them
by key.

Currently only instance_uuid is validated before recovery process.
All names and replicaset_uuid are checked only when recovery is done,
which can take a long time. It can be frustrating to users, which
have been waiting for several hours only to get name mismatch error.

Let's read the small part of snapshot file before calling box.cfg
in order to figure out, whether the names and uuids, passed to
configuration match the ones, saved inside the snapshot.

During config reload there's no sense in reading snapshot file, as
data is already saved inside spaces, let's read them. We still check
that names in config and names in spaces don't contradict during
config reload.

This commit also introduces methods, for getting names, which are
not set in snap (or memory), this'll be used in consequent commits
to set names automatically.

box.schema has a number of constants, e.g. IDs of system spaces,
which may be useful for the user. Let's allow to access box.schema
before box.cfg is called.

It is used in checking names, as we need to know, which snapshot spaces
to scan.

This commit introduces the new method for xlog module: xlog.meta().
It opens an xlog file, reads and returns the meta block of the file,
which includes its filetype, instance_uuid and vclocks.

It's needed in order to introduce checking of names inside the config
module in the following commit.

Needed for #8978

@TarantoolBot document
Title: xlog.meta(file-name) method

Description: Open an xlog file, and return its meta block.
Possible errors: Failed to open a file or it does not contain properly
formatted meta block.

Example:

```lua
tarantool> xlog = require('xlog')
---
...

tarantool> xlog.meta('00000000000000000000.snap')
---
- filetype: SNAP
  prev_vclock: {}
  instance_uuid: 87b2e60f-275c-4efa-9b0e-e9562e309692
  vclock: {}
...
```

Config's box.cfg applier scans snapshot_dir in order to find out,
whether recovery is going to be done. It's needed in order to determine,
whether the instance should be started into ro mode firstly.

Let's move info about snapshot into separate file in utils. The commit
also introduces snapshot_path, which will be used in the following
commits in order to validate names.

Add exports for fiber_set_name_n, fiber_name, fiber_id, fiber_csw &
fiber_find.

Also make fiber_set_joinable, fiber_set_ctx & fiber_get_ctx interpret
NULL as the current fiber.

@TarantoolBot document
Title: add basic fiber api to ffi exports.

5 basic functions can now be used via ffi api, which were previously
only accessible via lua api: fiber_set_name_n, fiber_name, fiber_id,
fiber_csw & fiber_find.

fiber_set_joinable now interprets NULL as current fiber.

Old: "Failed to allocate 2147483648 bytes in hash_table for key"
New: "Failed to allocate 16384 bytes in hash_table for key"

ERRINJ_INDEX_ALLOC cannot be used to test this error, because it fails
earlier, so ERRINJ_HASH_INDEX_REPLACE is introduced.

Recently added persistent instance/replicaset/cluster names have certain
validation rules (see #5029 and #9148). An instance name and a
replicaset name that are provided in a declarative configuration are
stored in the database, so they should follow the same rules.

This patch implements the validation for instance/replicaset/group
names, for `--name` CLI option and `TT_INSTANCE_NAME` environment
variable.

@TarantoolBot document
Title: Document `box_space_execute_priv` compatibility option

Historically, it was possible to grant the `execte` privilege on
a space although this action had no effect. Since Tarantool 3.0
it isn't allowed anymore. The new `compat` module option
`box_space_execute_priv` was added to revert to the old behavior.

Please create a documentation page for the new compatibility option at
https://tarantool.io/compat/box_space_execute_priv

Example:

```
tarantool> box.cfg{log_level = 'error'}
---
...

tarantool> box.schema.user.create('alice')
---
...

tarantool> box.schema.user.grant('alice', 'execute', 'space')
---
- error: Unsupported space privilege 'execute'
...

tarantool> require('compat').box_space_execute_priv = 'old'
---
...

tarantool> box.schema.user.grant('alice', 'execute', 'space')
---
...
```

Configuring log modules work differently with log.cfg and box.cfg:
box.cfg{log_modules=...} overwrites the current config completely while
log.cfg{modules=...} overwrites the currently config only for the
specified modules. Let's fix this inconsistency by making log.cfg behave
exactly as box.cfg.

Message body resides in one of rotating input buffers for the
connection. When we don't need message body anymore we advance the
reading end of the input buffer by the size of the message. But message
processing order can differ from the order of messages in the wire.
Thus this advancing a bit hacky. Let's instead mark the data in the
input buffer as read when we process all the messages in the input
buffer. We cannot reuse the buffer any earlier anyway.

The test is quite a flacky in debug ASAN CI workflow. The issue is test
check upper boundary of it's execution time. I run many instances of
this test on in parallel and got average time of 40s for memtex and 70s
for vinyl.

The time quota is already changed by the commit 84cb1e04 ("sql:
increase time quota for selectG test on vinyl") for laptops with HDD.
I did not check execution time for HDD though. I guess the bottleneck
for debug ASAN is CPU.

We install a signal handler that prints the stack trace on SIGSEGV,
SIGBUS, SIGILL, SIGFPE. The signal handler uses the current stack.
This works fine for most issues, but not for stack overflow, because
the latter makes the current stack unusable, leading to a crash in
the signal handler. Let's install an alternative signal stack in each
thread so that we can print the stack trace on stack overflow.

Note that we skip this for ASAN because it installs its own signal
stack. (Installing a custom stack would result in a crash.)

There are four problems we have to address to make this possible:

 1. memtx_engine_shutdown may delete the tuple referenced by
    box_tuple_last so that tuple_free, which is called later by
    box_free, will crash trying to free it. Fix this by clearing
    box_tuple_last in memtx_engine_shutdown.

 2. tuple_format_destroy and tuple_field_delete, called by it, expect
    all constraints to be detached. Let's destroy the constraints if
    this isn't the case. This effectively reverts commit 7a87b9a5
    ("box: do not call constraint[i].destroy() in
    tuple_field_delete()").

 3. tuple_field_delete, called by tuple_format_destroy, expects the
    default value function to be unpinned. Let's unpin it if this isn't
    the case. To avoid linking dependencies between the tuple and box
    libraries, we have to introduce a virtual destructor for
    field_default_func.

 4. The tuple_format unit test calls tuple_free after box_free. If
    box_free calls tuple_free by itself, this leads to a crash. Fix this
    by removing tuple_free and tuple_init calls from the test.

The motivation is to reduce time slip on Tarantool startup before
running init scripts. Internal ev time is set in fiber_init/ev_default_loop
and is not get updated until starting event loop. This causes
timeouts slip up to 0.3 in debug ASAN build in init script (see #9261).

Let's run event loop right at the beginning of the run_script_f before
executing any script. This way besides updating internal ev time we make
an explicit place of starting script event loop. Currently it is started
lazily when config script yields.

This will fix CI for PR https://github.com/tarantool/tarantool-ee/pull/572
for debug ASAN workflow.

We can also remove start_loop condition. It does not make sense now. It
was added in the commit 3a851430 ("Fix tarantool -e "os.exit()"
hang") but since then we start to stop event loop after handling
os.exit().

Also this fixes #9266. The issue is we don't have an event loop to run
on shutdown triggers if -e command line expression add such a trigger
and then call os.exit().

Tarantool supports two console protocols: text and binary. The binary
protocol is implemented with IPROTO EVAL request so the console module
reuses the net.box module to establish and maintain a binary connection.
Currently, instead of passing the original URI specified by the user to
net.box.connect as is, the console module parses the URI and passes the
host and port. As a result, extra information that may be specified in
URI parameters is lost. This prevents the user from connecting to the
binary console using the SSL transport because to use the SSL transport
the user must specify transport=ssl URI parameter.

During building an index in background, some transaction can perform a dml
request that affects space size (e.g. a replace), but the size will remain
