disable test cases for bugs not fixed in xtradb.

instead of disabling the test in disabled.def
(hoping that somebody someday will enable it),
skip it only for xtradb (not for innodb), and
only for the current xtradb version. the test
will enable itself automatically on the next

Split IO threads into ones that handle only read completion and ones that handle only write completion, as it was originally done, but got lost with "completion port" patch. The reason we need to have dedicated read and dedicated write threads is that read completion routine can block waiting for write io to complete, and in rare cases where all io threads are handling async reads, it can deadlock.
InnoDB: Remove HAVE_purify, UNIV_INIT_MEM_TO_ZERO, UNIV_SET_MEM_TO_ZERO.
The compile-time setting HAVE_purify can mask potential bugs.
It is being set in PB2 Valgrind runs. We should simply get rid of it,
and replace it with UNIV_MEM_INVALID() to declare uninitialized memory
as such in Valgrind-instrumented binaries.
os_mem_alloc_large(), ut_malloc_low(): Remove the parameter set_to_zero.
ut_malloc(): Define as a macro that invokes ut_malloc_low().
buf_pool_init(): Never initialize the buffer pool frames. All pages
must be initialized before flushing them to disk.
mem_heap_alloc(): Never initialize the allocated memory block.
os_mem_alloc_nocache(), ut_test_malloc(): Unused function, remove.

COMMUNICATION PACKETS, ERROR_CODE: 1160
If idle FEDERATED table is evicted from the table cache when
a connection to remote server is lost, query that initiated
eviction may fail.
If this query is executed by slave SQL thread it may fail as well.
An error of close was stored in diagnostics area, which was later
attributed to the statement that caused eviction.
With this patch FEDERATED clears an error of close.

Update all states when moving a non-transactional file to transactional. This fixes lp:887051
The counter handler_read_key (SSV::ha_read_key_count) is incremented
incorrectly.
The mysql server maintains a per thread system_status_var (SSV)
object. This object contains among other things the counter
SSV::ha_read_key_count. The purpose of this counter is to measure the
number of requests to read a row based on a key (or the number of
index lookups).
This counter was wrongly incremented in the
ha_innobase::innobase_get_index(). The fix removes
this increment statement (for both innodb and innodb_plugin).
The various callers of the innobase_get_index() was checked to
determine if anybody must increment this counter (if they first call
innobase_get_index() and then perform an index lookup). It was found
that no caller of innobase_get_index() needs to worry about the
SSV::ha_read_key_count counter.
This bug ensures that a live downgrade from an InnoDB 5.6 with WL5756 and
a database created with innodb-page-size=8k or 4k will make a version 5.5
installation politely refuse to start. Instead of crashing or giving some
indication about a corrupted database, it will indicate the page size
difference.
This patch takes only that part of the Wl5756 patch that is needed to
protect against opening a tablespace that is stamped with a different
page size.
It also contains the change in dict_index_find_on_id_low() just in case
a database with another page size is created by recompiling a pre-WL5756
InnoDB.
WITH LARGE BUFFER POOL
(Note: this a backport of revno:3472 from mysql-trunk)
rb://845
approved by: Marko
When dropping a table (with an .ibd file i.e.: with
innodb_file_per_table set) we scan entire LRU to invalidate pages from
that table. This can be painful in case of large buffer pools as we hold
the buf_pool->mutex for the scan. Note that gravity of the problem does
not depend on the size of the table. Even with an empty table but a
large and filled up buffer pool we'll end up scanning a very long LRU
list.
The fix is to scan flush_list and just remove the blocks belonging to
the table from the flush_list, marking them as non-dirty. The blocks
are left in the LRU list for eventual eviction due to aging. The
flush_list is typically much smaller than the LRU list but for cases
where it is very long we have the solution of releasing the
buf_pool->mutex after scanning 1K pages.
buf_page_[set|unset]_sticky(): Use new IO-state BUF_IO_PIN to ensure
that a block stays in the flush_list and LRU list when we release
buf_pool->mutex. Previously we have been abusing BUF_IO_READ to achieve
this.
