Fix BUG#14747: "Race condition can cause btr_search_drop_page_hash_index()
to crash".
Changes from snapshot innodb-5.0-ss52.
Note that buf_block_t::index should be protected by btr_search_latch
or an s-latch or x-latch on the index page.
btr_search_drop_page_hash_index(): Read block->index while holding
btr_search_latch and use the cached value in the loop. Remove some
redundant assertions.
Also fix 13778. When FOREIGN_KEY_CHECKS=0 we still need to check that
datatypes between foreign key references are compatible.
Also added test cases to 9802.
