Bugs fixed: - Bug #20791 valgrind errors in InnoDB Remove Valgrind warning of Bug #20791 : in new database creation, we read the doublewrite buffer magic number from uninitialized memory; the code worked because it was extremely unlikely that the memory would contain the magic number - Bug #21784 DROP TABLE crashes 5.1.12-pre if concurrent queries on the table remove update_thd() in ::store_lock() Also includes numerous coding style fixes, etc. See file-level comments for details.
