branches/zip: buf_LRU_invalidate_tablespace(): Do not unnecessarily
acquire the block_mutex for every block in the LRU list. Only acquire
it when holding buf_pool_mutex is not sufficient. This should speed up
the function and considerably reduce traffic on the memory bus and
caches.
I noticed this deficiency when working on Issue #157.
This deficiency popped up again in Issue #449 (Bug #35077),
which this fix does not fully address.

branches/zip: Drop temporary tables at startup.
This addresses the third aspect of Bug #41609.
row_mysql_drop_temp_tables(): New function, to drop all temporary
tables. These can be distinguished by the least significant bit of
MIX_LEN. However, we will skip ROW_FORMAT=REDUNDANT tables, because in
the records for those tables, that bit may be garbage.
recv_recovery_from_checkpoint_finish(): Invoke
row_mysql_drop_temp_tables(). Normally, if the .frm files for the
temporary tables exist at startup, MySQL will ask InnoDB to drop the
temporary tables. However, if the files are deleted, for instance, by
the boot scripts of the operating system, the tables would remain in
the InnoDB data dictionary unless someone digs them up by
innodb_table_monitor and creates .frm files for dropping the tables.

branches/zip: buf_page_get_gen(): Obey recv_no_ibuf_operations
and do not call ibuf_merge_or_delete_for_page() in crash recovery,
before the redo log has been applied.
This could cure some hard-to-repeat, hard-to-explain bugs
related to secondary indexes.
A possible recipe to repeat the bug:
1. update a secondary index leaf page on a compressed table
2. evict the page from the buffer pool while it is still dirty
3. ibuf_insert() something for the page
4. crash
5. crash recovery; ibuf merge would be done too early,
before applying redo log to the sec index page or the ibuf pages

log_sys->written_to_all_lsn does not accurately represent the LSN
upto which write and flush has taken place. Under a race condition
it can fall behind log_sys->flushed_to_disk_lsn which is accurate.
Besides written_to_all_lsn is redundant as currently InnoDB supports
only one log group.
