Option memtx_tx_manager_use_mvcc_engine changes the behavior of
transaction execution workflow. Usually that is implemented as
direct check of memtx_tx_manager_use_mvcc_engine. But there are
places in the code that rely on the fact that some pointers are
set to not null if the engine is enabled. That's a bit confusing.

Let's always check for memtx_tx_manager_use_mvcc_engine option
when it's needed to determine which workflow must be executed.

Note that checking of memtx_tx_manager_use_mvcc_engine option is
more correct: in case of delete of nothing (delete statement when
a tuple was not found by given key) all the pointers including
old_tuple and new_tuple are null, while logically we still need
to use mvcc execution workflow. Note also that in this case the
mvcc engine does (and must do) almost nothing, so there was no
bug in the previous behaviour.

The status isn't used anywhere - to set the proper error when an aborted
transaction is attempted to be used, we check out transaction flags
(TXN_IS_CONFLICTED, TXN_IS_ABORTED_BY_YIELD, TXN_IS_ABORTED_BY_TIMEOUT).
Let's use TXN_ABORTED instead.

While we are at it, also set the transaction status to TXN_ABORTED when
a transaction is aborted by yield or timeout and use it instead of
checking flags where appropriate, since it's more convenient.

    Tarantool 2.10 doesn't set the callbacks, so no behavior should

The coverage workflow is a part of the default testing, so there is no
sense to run this workflow when the 'full-ci' label is set. Moreover, it
cancelled the run of the default testing and started the run of the full
testing due to workflow `concurrency`.

By default, a workflow only runs when a `pull_request` event's activity
type is `opened`, `synchronize`, or `reopened`. That's why there is no
sense in the following construction:

  pull_request:
    types: [ opened, reopened, synchronize ]

So just removed the line related to event's activity type.

A jiggle in tarantool's initialization code can lead to trace numbers
above 9. We can either:

* accept trace numbers above 9 in the test
* or drop traces from the initialization code in the test and assume
  that the new trace will have number 1.

Igor Munkin suggested to stick with the second approach to avoid
dependency on the initialization code.

Currently all non-main threads have all the signals blocked, however
according to `man pthread_sigmask':

> If SIGBUS, SIGFPE, SIGILL, or SIGSEGV are generated while they
> are blocked, the result is undefined, unless the signal was
> generated by kill(2), sigqueue(3), or raise(3).

On macOS they are actually blocked, causing the faulting instruction
to loop indefinitely. While on Linux they are not blocked, however the
signal handler registered by sigaction is not executed. Don't block them.

Closes #8023
Closes #8083

NO_DOC=bugfix

(cherry picked from commit 706bfea4)

There are 4 fatal signals that cannot be blocked by sigmask if they
are caused by the CPU exception (rather than kill, sigqueue or raise):
SIGILL, SIGBUS, SIGFPE, SIGSEGV. Currently the crash module handles
only SIGSEGV and SIGFPE. This patch adds handlers for SIGBUS and SIGILL.
SIGBUS is usually raised by macOS on access to the unmapped memory, and
SIGILL is possible, for example, while running AVX version of memcpy on
a CPU without AVX support.

Faulting address siginfo->si_addr is valid for all these signals, so
print it unconditionally.

Use O_CLOEXEC flag instead.

If Tarantool is forked before executing box.cfg{}, e.g. using io.popen(),
the child process could start with stdin linked to /dev/urandom.
This happens because wal_writer_singleton and vy_log_writer are not yet
initialized, i.e. `fd' fields are 0, then atfork child handler wal_atfork()
is called. It checks that xlog is opened (the check succeeded as 0 != -1)
and closes its fd 0, in fact closing stdin (twice). Next, Tarantool opens
the file /dev/urandom during initialization, and it receives the lowest
unused file descriptor, which is 0. Then luaL_loadfile() loads stdin as a
Lua chunk, in effect reading random numbers.

This happens on glibc 2.28 and older, as newer versions do not invoke
atfork handlers during io.popen():

Workflow submodule_update now brings latest commits in stable branches
further to tarantool/sdk, where integration tests can run with other
enterprise products and modules.

In tarantool/tarantool-ee a pull request is still opened, so the
maintainers can merge it at any time.

In tarantool/sdk the test branches are named in the following pattern:
`TarantoolBot/test-ce-master`
`TarantoolBot/test-ce-2.10`
and so on. This pattern can be easily distinguished by workflows,
which run integration tests and alert developers on failures.
It is also consistent with branches with the same purpose of integration
testing, that are created by the sdk_test workflow:
`TarantoolBot/test-ce-{feature_branch_name}`

The 'copy' ptr is checked for NULL after dereferencing. Found by PVS.

https://jira.vk.team/browse/TNT-698

It can hardly result in a null-ptr dereference, because vy_stmt_dup()
uses malloc(), which doesn't normally fail (instead, the OOM killer just
kills the process if there's a severe shortage of memory, see #3534).
Still, PVS rightfully complains about it so let's fix it.

Currently, we stop without checking the authentication request body if
the specified user doesn't exist. As a result, one can check if a user
exists by sending a malformed authentication request: for an existing
user, the server will reply with ER_INVALID_MSGPACK error while if the
user doesn't exist, the error will be set to ER_CREDS_MISMATCH. To fix
this, let's parse the authentication request body even if the user
doesn't exist.

    (after) {"foo":"bar","pid":666}

3. Now if 'message' field is absent, it is set to the first field of the
   table (JSON log format)

   tarantool> log.info({'Hello, world', key = 'value'})
   (before) {[...], "1":"Hello, world", "key":"value", [...]}
