This fixes the value returned by the getNumberOfArguments() by the
s2RectAdd and the s2RectContains functions. Only 3 arguments are
used by these functions and not 4:
- low s2Point of rectangle
- high s2Point of rectangle
- given s2Point
The given s2Point is used to groow the size of the bounding rectangle to
include the given S2Point in case of the s2RectAdd function. In case
of s2RectContains, the function determines if the bounded rectangle
contains the given point.
PS: I wonder if it's more apt to call rectAdd as rectGrow since
it's used to grow the size of a given rectangle.
This will fix race with DatabaseCatalog::loadMarkedAsDroppedTables(),
since MaterializeMySQL, and MaterializedMySQLSyncThread in background,
will be started earlier then
DatabaseCatalog::loadMarkedAsDroppedTables() and will move those tables
to metadata_dropped, and after loadMarkedAsDroppedTables() will start
and try to load partially dropped tables and will hit UUID overlap:
