Language in `local_read()` used to be set to `box.session.language` while
the latter is always `nil` and `set_language()` sets `self.language`.

Now the language in `local_read()` is identified correctly. This is
required for performing continuation check (gh-4317) on any language
while the check for complete lua statement happens only in Lua mode.

In the test we start replicas only with master in box.cfg.replication.
We cannot use bootstrap_strategy = 'auto' mode, which is default, as
it properly works only when all participants of the cluster are listed
in replication parameter. Sometimes, when one replica connects to the
master, the other one has already successfully joined, so the first
replica sees in ballot, that it doesn't have all nodes from cluster
in box.cfg.replication and fails to start.

Let's use 'legacy' bootstrap strategy for now.

If the 'after' key is less than the search key in case of ge/gt or
greater than the search key in case of le/lt, the iterator either
crashes (vinyl) or returns invalid result (memtx). This happens because
the engine implementation doesn't expect an invalid 'after' key.
Let's fix this by raising an error at the top level in case the 'after'
key doesn't meet the search criteria.

Currently, if the position isn't compatible with the index, we raise
an error like "Invalid key part count ...". From this error it's
difficult to figure out whether it's for the given iterator position of
for the search key. Let's always raise ER_ITERATOR_POSITION in this
case. Later on we'll use stacked diag to add extra error info.

We need to compare a tuple position with a search key in select() and
pairs() to make sure the tuple position meets the search criteria. The
problem is that we strip the MessagePack header from the position while
key_compare() takes keys with headers. Let's make key_compare take keys
without headers like the rest of comparator functions. Since in Vinyl we
often need to compare keys with headers, we also add vy_key_compare()
helper function.

We use coio_connect() to connect the replica to a remote peer. It
implies no timeout, and does a non-blocking connect() to the peer and
then waits for the socket to become writable indefinitely.

When the remote peer changes its IP address, connect() might try
connecting to the old address for as long as ~ 2 minutes (given the
default tcp_syn_retries value of 6).

This blocks replica from trying to reconnect to the updated address and
is pretty inconvenient.

Let's use coio_connect_timeout() instead and use
replication_disconnect_timeout() as a timeout, like everywhere else in
master-replica communication.

Force recovery needs to follow the following logic: any unsuccessful system
space request must make recovery fail (including failure to decode an xrow,
when we are not sure we have finished processing system space request). If
the request is a non-insert one (e.g., raft or synchro) or addresses a user
space, it means we have finished processing system space requests, and from
this moment force recovery can be enabled — change the behaviour
accordingly.

We assume the request order in the snapshot is the following:
1. system space requests;
2. user space requests;
3. non-insert requests (e.g., raft or synchro).

Refactor the force recovery logic: add a enumeration to track snapshot
recovery state and add a new diagnostic for the case when the snapshot
contains has no system spaces.

Closes #7974

NO_DOC=bugfix

In some cases we don't have the whole space struct, but we want to
determine whether the provided space identifier corresponds to a system

We often commit snap/xlog files for tests. A snap/xlog file is binary,
but it contains a plain text header and, as a result, may be identified
as a text file by git, which would enable checkpatch checks for it.
Apparently, we don't need to check these files so let's force git to
identify them as binary.

This also changes the order in which spaces are stored in .snap files.

Currently space_foreach() iterates over spaces in the following order:
1. Spaces with id in the range [256..510], ordered by id;
2. All other (non-system) spaces in unspecified order.

This patch changes the order to:
1. Spaces with id in the range [256..511], ordered by id;
2. All other (non-system) spaces, ordered by id.

Strict ordered of non-system spaces is required by users who iterate
over .snap files with xlog.pairs().

@TarantoolBot document
Product: Tarantool
Title: Update the description of .snap file format
Root document: https://www.tarantool.io/en/doc/latest/dev_guide/internals/file_formats/#the-snapshot-file-format

Change "the .snap file’s records are ordered by space id" to:

Since Tarantool 3.0 the .snap file's records have the following order:
1. System spaces (id >= 256 && id <= 511), ordered by id;
2. All other (non-system) spaces, ordered by id.

In older versions of Tarantool the order of non-system spaces is
unspecified.

Patch fixes a bug when body in response couldn't be decoded:

NO_WRAP
```
tarantool> httpc = require('http.client').new()
tarantool> response = httpc:get('https://jsonplaceholder.typicode.com/todos/1'

)
tarantool> response:decode()

---
- error: 'builtin/http.client.lua:301: attempt to index field ''decoders'' (a nil
    value)'
...
```
NO_WRAP

Now response object contains table with decoders defined by user in his
http client instance. We hide this table on response serialization by
adding underscore because decoders there is not a part of API.
