Bugs Fixed

If a bitmap write I/O errors happened in the background log tracking thread while a FLUSH CHANGED_PAGE_BITMAPS is executing concurrently it could cause a server crash. Bug fixed #1651656.

Querying TABLE_STATISTICS in combination with a stored function could lead to a server crash. Bug fixed #1659992.

Queries from the INNODB_CHANGED_PAGES table would needlessly read potentially incomplete bitmap data past the needed LSN range. Bug fixed #1625466.

It was not possible to configure basedir as a symlink. Bug fixed #1639735.
