The function `datetime_gmtoff()` has been introduced in commit aec6fbac1f22 ("datetime: implement date.isdst") for a function `datetime_increment_by()`. In commit 6ca072853034 ("datetime: fix interval arithmetic for DST") the function `datetime_increment_by()` has been updated and call of the function `datetime_gmtoff()` was removed. `datetime_gmtoff` is dead code now. The patch removes `datetime_gmtoff()`. NO_CHANGELOG=codehealth NO_DOC=codehealth NO_TEST=codehealth (cherry picked from commit 625afe418151de1015483ed24acaa57e1f85efb3)

Since tarantool/luajit@a16313f large exponent double strings are not considered convertible to number. It broke encoding lua objects to YAML because single quotes weren't considered necessary for decoding. This commit adds wrapping of every string containing infinite double values into a single quotes. Closes #10164 NO_DOC=bug fix (cherry picked from commit 7c3f42590240525d2e543305b6c289ddb30054a2)

This patch adds encapsulation for IPv6 addresses in brackets when calling uri.format (as per RFC 2732). Closes #9556 NO_DOC=bugfix (cherry picked from commit a49ec23b85edb684744eb525427465dfa4f660e1)

Before this patch `uri.parse(<uri-string-with-ipv6-addres>)` did not work correctly. In particular, it did not parse an IPv6 address if it contained `A-F`. It is a regression caused by commit 1376aad9b3fd ("Refactor src/uri.rl to support RFC3986 and add Lua bindings"). This patch fixes a bug where characters `A-F` are not supported in IPv6.

When checkpoint fails, we abort it in all engines even if it wasn't started successfully. If it fails right from the start so that checkpoint in memtx wasn't started, assertion in `memtx_engine_abort_checkpoint` fails - memtx doesn't expect that checkpoint will be aborted if it failed to start. Let's do the same thing as vinyl does - no-op if there is no checkpoint in progress.

We've had a number of issues when Tarantool was permanently broken (unable to recover after restart) because of a bad vylog record. The `force_recovery` mode didn't help so the user would have no other choice but to rebootstrap. A funny thing is those bugs were usually caused by a race between the garbage collector and dump/compaction when a vylog record was written for a dropped index. The worst thing that could happen if we ignored such a bad record is an unused run file not deleted from disk. Apparently, this is better than a permanent recovery failure so let's support the `force_recovery` mode in vylog. The tricky part here is handling checkpoint after restart. The problem is that to create a vylog checkpoint, we load the previous vylog file so we have to ignore errors if it was loaded in the `force_recovery` mode. Closes #10292 NO_DOC=bug fix (cherry picked from commit c68e8a8e029d849d68c6018ed00b5a79cc769222)

The vinyl metadata log processor allocates its internal objects either from malloc or region, neither of which should fail for small allocations. Let's switch to xalloc to simplify the code. A good thing about this change is that now we can ignore all errors raised by vy_log_record_decode() and vy_recovery_process_record() if the force_recovery flag is set (see the next commit).
