it.

MDEV-27990: Incorrect behavior of JSON_OVERLAPS() on warning

Analysis: In case of error while processing json document, we goto
error label which eventually return 1 instead of 0.
Fix: Return 0 in case of error instead of 1.

MDEV-27677: Implement JSON_OVERLAPS()

1) When at least one of the two json documents is of scalar type:
     1.a) If value and json document both are scalar, then return true
          if they have same type and value.
     1.b) If json document is scalar but other is array (or vice versa),
          then return true if array has at least one element of same type
          and value as scalar.
     1.c) If one is scalar and other is object, then return false because
          it can't be compared.

  2) When both arguments are of non-scalar type and below conditons
      are satisfied then return true:
      2.a) When both arguments are arrays:
           Iterate over the value and json document. If there exists at
           least one element in other array of same type and value as
           that of element in value.
      2.b) If both arguments are objects:
           Iterate over value and json document and if there exists at least
           one key-value pair common between two objects.
      2.c) If either of json document or value is array and other is object:
           Iterate over the array, if an element of type object is found,
           then compare it with the object (which is the other arguemnt).
           If the entire object matches i.e all they key value pairs match.

MDEV-28185 InnoDB generates redundant log checkpoints

The comparison on the checkpoint age (number of log bytes
written since the previous checkpoint) is inaccurate, because
the previous FILE_CHECKPOINT record could span two 512-byte
log blocks, which will cause the LSN to increase by the size of the
log block header and footer.

We will still generate a redudant checkpoint if the previous
checkpoint wrote some FILE_MODIFY records before the FILE_CHECKPOINT
record.
