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. innobase/btr/btr0sea.c: Changes from innodb-5.0-ss52 innobase/dict/dict0dict.c: Changes from innodb-5.0-ss52 innobase/dict/dict0load.c: Changes from innodb-5.0-ss52 innobase/include/buf0buf.h: Changes from innodb-5.0-ss52 innobase/include/dict0dict.h: Changes from innodb-5.0-ss52 innobase/include/dict0load.h: Changes from innodb-5.0-ss52 innobase/include/rem0cmp.h: Changes from innodb-5.0-ss52 innobase/rem/rem0cmp.c: Changes from innodb-5.0-ss52 innobase/row/row0mysql.c: Changes from innodb-5.0-ss52 mysql-test/r/innodb.result: Changes from innodb-5.0-ss52 mysql-test/t/innodb.test: Changes from innodb-5.0-ss52 sql/ha_innodb.cc: Changes from innodb-5.0-ss52 sql/ha_innodb.h: Changes from innodb-5.0-ss52
