This reverts commit ace88542.

That commit disabled repl in tarantool for debugger console session
because debugger console wasn't compatible with Tarantool console,
i.e. this code hang in terminal:

```lua
tarantool> dbg = require 'luadebug'
tarantool> dbg()
```

With the previous patch in the patchset, full readline support and
console compatibility was introduced. Thus, no need to disable repl.

Implemented readline history and autocomplete by reusing
readline facilities of Tarantool console. They used to be
being hidden once Lua 'console' module is loaded. With c432e9e9
(lua: don't use public module name as internal one), now they
are available as 'console.lib'.

Title: proper readline support in readline

Similar to tarantool interactive console, tdbg now uses readline
for its shell. It enables handier input editing, command history
and so on.

(cherry picked from commit 92222451)

`console_debugger_session_test.lua` can be simplified and made more
stable with interactive_tarantool helper. With the new
`read_untill_prompt()` helper function, dbgr prompt can be used as
end-of-output marker instead of '...' in yaml-outputting main console.
This way, popen results are unambiguous and no retries are required.
At the same time, dbgr prompt is now expected with every result, thus
there is no need for an extra check. But `continue` command usually
reaches the end of the script and exits debugger, thus
'<END_OF_EXECUTION>' marker was introduced.
Empty stderr and header check were moved to interactive_tarantool helper.
This patch breaks the test without debugger readline support patch,
that is next in the patchset.

The following changes were applied to `interactive_tarantool` helper
to adapt it for debugger tests:
* compared commands are now stripped from tabs and color codes too
* now each command independent of control symbols is being stripped
  before comparison in `execute_command()`
* created internal new function that is called from both `new()` and
  `new_debugger()`
* now user defined prompt can be set up from `new` and `new_debugger()`
* now there are several less typos in comments

test/unit/guard.cc calls stack_break_f() recursively until the stack
overflows and a signal is fired, however it relies on undefined behavior
when compares pointers to local variables. Fixed by comparing
__builtin_frame_address() instead.

One of the examples of this UB is when ASAN allocates local variables on
fake stacks, in that case the test completes without the stack overflow.

Also this patch disables ASAN for stack_break_f() to keep the array on the
fiber stack (see the corresponding comment) and marks it as volatile to
avoid optimizing it away by the compiler.

Runtime tuple formats are reusable, which means that a tuple format
returned by runtime_tuple_format_new may not be brand new, but actually
be used by a Lua object. As a result, if we call any function that may
trigger Lua GC between runtime_tuple_format_new and tuple_format_ref,
the tuple format may be deleted, leading to a use-after-free bug. This
is what happens in lbox_tuple_format_new. Fix this issue by taking a
reference to the format before pushing a cdata object to the Lua stack
in lbox_push_tuple_format.

The issue was fixed in the master branch by commit 28ec245d ("lua:
fix heap-use-after-free bug in tuple format constructor"). This isn't
a clean cherry-pick because the code changed quite a bit.

Fuzzing test for LuaJIT generates random Lua programs and executes them.
We want to build a fuzzing test that will produce Lua programs that will
not contain semantic errors and will trigger as much as possible
components in LuaJIT.

This proposed patch introduces metrics that gathered after running the
test. LuaJIT metrics gathered using LuaJIT getmetrics module [1]. All
gathered metrics test will output after running with a finite number of
runs or finite duration of time (options `-runs` and `-max_total_time`)
or after sending SIGUSR1 to a test process.

The `__sanitizer_start_switch_fiber()` function takes a pointer as the
first argument to store the current fake stack if there is one (it is
necessary when stack-use-after-return detection is enabled). When leaving a
fiber definitely, NULL must be passed so that the fake stack is destroyed.

Before this patch, NULL was passed for dead fibers, however this is wrong
for dead fibers that are recycled and resumed. In such cases ASAN destroys
the fake stack, and the fiber crashes trying to use it in `fiber_yield()`
upon return from `coro_transfer()`.

There must be a couple of rules:
* foreign key from non-temporary space to temporary space must be
  forbidden since after restart all existing links will be broken.
* foreign key from non-local space to local space must be forbidden
  on any replica all existing can be broken.

This patch implements the rules.

Closes #8936

(cherry picked from commit 7d23b339)

In #7309 a truncation of a space that was referenced by foreign
key from some other space was prohibited.

It appeared that this solution is too bothering since a user can't
truncate a space even if he truncated referring space before that.

Fix it by allowing space truncate if referring spaces are empty.
Also allow drop of the primary index in the same case with the
same reason: logically the index along with all space data is
not needed for consistency if there's no referring data.

Note that by design space truncate is implemented quite similar
to space drop. Both delete all indexes, from secondary to primary.
Since this patch allows deletion of the primary index (which is
the action that actually deletes all data from the space), this
patch changes the result of space drop too: the space remains
alive with no indexes, while before this patch it remained alive
with no secondary indexes but with present primary. In both cases
the behaviour is quite strange and must be fixed in #4348. To
make tests pass I had to perform drop in box.atomic manually.

All LuaJIT related LSan warnings were suppressed in the scope of the
commit 985548e4 ("asan: suppress all
LSAN warnings related to LuaJIT"), since all compiler flags tweaks were
enclosed in LuaJIT CMake machinery. As a result of the commit in LuaJIT
submodule tarantool/luajit@a86e376 ("build: introduce LUAJIT_USE_ASAN
option") ASan and LSan support has been finally added to LuaJIT runtime,
so it was decided to remove LSan suppressions for LuaJIT functions.
Unfortunately, it was not so easy as it looked like.

At first, Lua global state is not closed properly at Tarantool instance
exit (see <tarantool_free> in src/main.cc and <tarantool_lua_free> in
src/lua/init.c for more info), so LSan false-positive leaks are detected
(for more info, see #3071). Hence, the original LSan suppression for
lj_BC_FUNCC is returned back (temporarily) until the aforementioned
issue is not resolved.

Furthermore, the internal LuaJIT memory allocator is not instrumented
yet, so to find any memory faults it's worth building LuaJIT with system
provided memory allocator (i.e. enable LUAJIT_USE_SYSMALLOC option).
However, again, since Tarantool doesn't finalize Lua universe the right
way, so running Tarantool testing routine with LUAJIT_USE_SYSMALLOC
enabled generates false-positive LSan leaks. Return back here to enable
LUAJIT_USE_SYSMALLOC, when #3071 is resolved.

Last but not least, the default value of fiber stack size is 512Kb, but
several tests in test/PUC-Rio-Lua-5.1-test suite in LuaJIT submodule
(e.g. some cases with deep recursion in errors.lua or pm.lua) have
already been tweaked according to the limitations mentioned in #5782,
but the crashes still occur while running LuaJIT tests with ASan support
enabled. Experiments once again confirm the notorious quote that "640 Kb
ought to be enough for anybody".

Anyway, LuaJIT tests are added to <test-release-asan> target in .test.mk
and LUAJIT_TEST_ENV is extended with required ASan and LSan options.

The is_new and is_old methods are the same for all compat options so

is that it removes is_new and is_old from serialization:

      containing "\n\n" substring. The new behavior makes all multiline string output
      as single text block which is handier for the reader, but may be incompatible
      with some existing applications that rely on the old style.

Applier thread uses lsregion to allocate the messages for tx thread. The
messages are freed upon return to the applier thread using a
corresponding lsr_id.

Due to a typo, one of the lsregion allocations was made with a postfix
increment of lsr_id instead of the prefix one. Essentially, part of a
new message was allocated with an old lsr_id, and might be freed early
by a return of a previous message.

Fix this.
