  branches/zip: buf_LRU_invalidate_tablespace(), buf_LRU_free_block():

  branches/zip: buf0lru.c: Improve debug assertions.

  buf_LRU_block_free_non_file_page(): ut_ad(block) before dereferencing block.

  buf_LRU_block_remove_hashed_page(): Forbid buf_pool_mutex_exit() while
  calling buf_buddy_free().  Callers of buf_LRU_block_remove_hashed_page()
  assume that the buffer pool mutex will not be released and reacquired.

  branches/zip: Add assertions that the kernel_mutex is being held
  while accessing table->locks or un_member.tab_lock.locks.
  This is related to Issue #158.  According to static analysis,
  the added debug assertions should always hold.

  lock_table_has_to_wait_in_queue(), lock_queue_iterator_reset(),
  lock_queue_iterator_get_prev(), add_trx_relevant_locks_to_cache(),
  fetch_data_into_cache(): Add ut_ad(mutex_own(&kernel_mutex)).

    branches/5.1: Merge r4003 from branches/5.0:

    rec_set_nth_field(): When the field already is SQL null,
    do nothing when it is being changed to SQL null. (Bug #41571)

    Normally, MySQL does not pass "do-nothing" updates to the storage engine.
    When it does and a column of an InnoDB table that is in ROW_FORMAT=COMPACT
    is being updated from NULL to NULL, the InnoDB buffer pool will be corrupted
    without this fix.

    branches/5.1: lock_is_table_exclusive(): Acquire kernel_mutex before
    accessing table->locks and release kernel_mutex before returning from
    the function.  This fixes a portential race condition in the
    "commit every 10,000 rows" in ALTER TABLE, CREATE INDEX, DROP INDEX,
    and OPTIMIZE TABLE. (Bug #42152)
