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.

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.

A read source iterator stores statements in a vy_history object using
vy_history_append_stmt(). If a statement can be referenced, it's
reference counter is incremented. If it can't, i.e. it belongs to a
memory source, it's stored in a vy_history object without referencing.

This works fine because memory sources are append-only. A problem arises
only when we get to scanning disk sources. Since we yield while reading
disk, a dump task may complete concurrently dropping the memory sources
and possibly invalidating statements stored in the iterator history.
Although we drop the history accumulated so far and restart the
iteration from scratch in this case, there's still an issue that can
result in a use-after-free bug in vy_read_iterator_next().

The problem is that we access the current candidate for the next
statement while evaluating a disk source after a disk read. If 'next'
refers to a referenced statement, it's fine, but if it refers to a
statement from a memory source, it may cause use-after-free because
the memory source may be dropped during a disk read.

To fix this issue, let's make vy_history_append_stmt() copy statements
coming from memory sources. This should be fine performance-wise because
we copied memory statements eventually in vy_history_apply() anyway,
before returning them to the user.

Note that we also have to update vy_read_iterator_restore_mem() because
it implicitly relied on the fact that 'next' coming from a memory source
can't be freed by vy_mem_iterator_restore(), which cleans up the memory
source history. Now, it isn't true anymore so we have to temporarily
take a reference to 'next' explicitly.

In scope of the commit 82f4b4a3 ("lib/core/fiber: Increase default

512 Kb (you can find the reasons in the aforementioned commit message
and in https://github.com/tarantool/tarantool/issues/3418 description).

Some of the tests in test/PUC-Rio-Lua-5.1-test suite in LuaJIT repo
(e.g. some cases with deep recursion in errors.lua or pm.lua) have
already been tweaked according to the limitations mentioned in
https://github.com/tarantool/tarantool/issues/5782, but the crashes
still occurs while running LuaJIT tests with ASan support enabled.

To make the testing routine more convenient, FIBER_STACK_SIZE option is
introduced to Tarantool CMake machinery. One can provide the size either
by raw digits (i.e. in bytes) or using Kb/Mb suffixes for convenience.

A couple of important nits:
* If the given value is not a multiple of 4Kb, CMake machinery adjusts
  it up to the nearest one greater than this value.
* If the adjusted value is less than 512Kb, configuration fails with the
  corresponding CMake fatal error.

Test uses a popen module that starts tarantool process in background
mode. Tarantool process started in background mode forks a new process
and closes a parent, after that popen loses a PID of the started process
and `ph:kill()` and `ph:terminate()` doesn't work anymore. It leads to
non-terminated tarantool processes after running the test.

Patch fixes that by running `kill` using os.execute with a PID of
tarantool process written to a pid file.

When a space is altered, we abort all in-progress transactions and delete
all stories related to that space: the problem is we don't delete the
stories' read gaps, which are also linked to the stories' transactions,
which get cleaned up on transaction destruction — this, in turn, results in
heap-use-after-free. To fix this, clean up stories' read gap in
`memtx_on_space_delete` — we don't do this in `memtx_tx_story_delete` since
it expects the story to not have any read gaps (see
`memtx_tx_story_gc_step`).

Previous attempt to fix flakiness in commit 6a2c73f8 ("test: fix
flakiness in gh_6128_background_mode_test") used a constant buffer size
in check_err_msg function. Tarantool 2.10 has a bit bigger log before a
desired message that other versions of Tarantool and it leads to a this
resulted in a truncated message ("entering the even" instead of
"entering the event loop"). Patch replaces check_err_msg()
implementation to grep_log used in luatest, it reads the whole log.

Also patch renames check_err_msg to check_msg, because "entering the
event loop" is not an error message.

Test runs an external process with tarantool that writes to a log file.
Then test reads that log file and searches a string with required
message in it (see function check_err_msg). Test was flaky on macOS and
I suspect it was happening due to a high log level - timeout was not
enough to wait message in the log file.

Patch decreases a log level to a default value and replaces io
functions with the similar alternatives in a fio module. Using
fio functions allows to not block fibers.

The xlog reader Lua module uses the xlog_cursor_next_row, which decodes
the row header with xrow_header_decode. The latter silently ignores any
unknown fields, which complicates catching bugs when garbage is written
to a row header by mistake, for example, see #8783.

Let's parse a row header without using xrow_header_decode in the xlog
reader module, like we parse a row body, and output all unknown/invalid
keys as is.

To do that, we have to extend the xlog cursor API with the new method
xlog_cursor_next_row_raw that returns a pointer to the position in the
tx buffer where the next xrow is stored without advancing it. To avoid
a memory leak in case the caller fails to parse an xrow returned by this
function, we also have to move the call to xlog_tx_cursor_destroy from
xlog_tx_cursor_next_row to xlog_cursor_next_tx.

While we are at it,
 - Don't raise an error if a key type encountered in a row body is
   invalid (not an integer). Instead, silently ignore such keys.
 - Remove the useless body MsgPack validness check because we already
   check it after decoding the header.
 - Add error injection based tests to check all the corner cases.

There's case when a transaction is rolled back from prepared
state. This happens when WAL fails, synchronized replication
confirmation failure or perhaps in other similar cases. By design
other RW transactions and transactions with READ_COMMITTED
isolation level are allowed to read prepared state. All these
transactions must be aborted in case of rollback of prepared
transaction since they definitely have read no more possible
database state.

This patch implements this abortion.

Closed #8654

NO_DOC=bugfix

(cherry picked from commit 54986902)

Rollback is rather complicated part if MVCC implementation that
is meant to handle two kinds of rollback:
* rollback from in-progress state, if box.rollback() is called.
* rollback from prepared state, when WAL fails.
Unfortunately the last one was not properly tested and surely
has at least one flaw. When an inserting transaction becomes
prepared its stories could be linked as deleted (via del_stmt
pointer) by other in-progress transactions in order to maintain
correct visibility. The problem is that in case of rollback of
such prepared transaction those links remained. Broken links
breaks the chain structure, and some older changes (that were
linked as deleted before that hapless preparation) can become
visible to other transaction.

Refactor, simplify a bit that part of code and fix the issue
described above; cover with tests.

Now there are three kinds of very close trackers:
* The transaction have read some tuple that is not committed and
  thus not visible. This kind is now stored as gap_item with
  is_nearby = false.
* The transaction made a select or range scan, reading a key or
  range between two adjacent tuples of the index. This kind is
  stored as gap_iteam with is_nearby = true.
* A transaction completed a full scan of unordered index. This
  kind is stored as full_scan_item.

All these trackers serve for the same thing: to record a fact
that a transaction read something but didn't see anything.

There are some problems with the current solution:
* gap_item with is_nearby = false has several unused members that
  just consume space.
* bool is_nearby flag for type descriptin is an ugly solution.
* full_scan_item is separated from logically close items.

This commit joins all these trackers under one base (that is
struct gap_item_base) and solves problems above.

Now read trackers are used both for cases when a transaction has
read an existing value and it has read nothing (read by key but
there was no visible tuple in this place). For latter case an
additional index_mask was used to identify from which index the
read was done. Along with that there was per-index interval gap
trackers.

This patch divides area of responsibility between read trackers
and gap tracker in the following way:
* Reads of existing visible values are stored in read trackers.
* Reads of non-existing or non-visible values are store in gap
  trackers.

This new approach allows to provide new invariants: gap trackers
are stored only at top of chain, and read trackers are stored
only at topmost committed story in chain.
