Commit Message

box: fix crash on rollback on memtx memory OOM and massive index change

We cannot tolerate index extent memory allocation failure on rollback.
At the same time it is not practical to reserve memory because a whole
index can easily be changed on rollback if read view is created before
rollback.

So in case of rollback and memtx memory OOM let's allocate outside the
memtx arena limited by quota.

Now part of the index can reside outside memtx arena. But regularly the
index changes will move this part back to the memtx arena. Until next
such situation of course.

Closes #10551
