A change in the default values of some config parameters
caused this test to fail, adjust the test and make it more
robust so it does not fail for the same reason in the future.

release a dirty page in the middle of a mini-transaction. Replace the code
with an assertion that checks for this condition.

Original svn revision was: r6330.

      
Silence the UNIV_SYNC_DEBUG assertion failure while upgrading old data files
to multiple rollback segments during server startup. Because the upgrade
takes place while InnoDB is running a single thread, we can safely ignore the
latching order checks without fearing deadlocks.
      
innobase_start_or_create_for_mysql(): Set srv_is_being_started = FALSE
only after trx_sys_create_rsegs() has completed.
      
sync_thread_add_level(): If srv_is_being_started, ignore latching order
violations for SYNC_TRX_SYS_HEADER and SYNC_IBUF_BITMAP.

Create all the non-IO threads after creating the extra rollback segments.

Patch originally from Marko with some additions by Sunny.

  
Get rid of at least on suspicious path. Ensure that the purge thread
doesn't acquire a mutex after it has signalled shutdown.

InnoDB 1.1.1 was released with MySQL 5.5.5-m3

(resolving conflicts in mysql-test/suite/rpl/t/rpl_sync-slave.opt and
configure.cmake)

This patch was originally developed by Vladislav Vaintroub.
The main changes are:

 * Use TryEnterCriticalSection in os_fast_mutex_trylock().
 * Use lightweight condition variables on Vista or later Windows;
   but fall back to events on older Windows, such as XP.

This patch also fixes the following bugs:
  bug# 52102 InnoDB Plugin shows performance drop compared to InnoDB
             on Windows
  bug# 53204 os_fastmutex_trylock is implemented incorrectly on Windows

This bug is a design flaw of the fix for the bug#33546. It assumed that an
item can be used only in one comparison context, but actually it isn't the
case. Item_cache_datetime is used to store result for MIX/MAX aggregate
functions. Because Arg_comparator always compares datetime values as INTs when
possible the Item_cache_datetime most time caches only INT value. But
since all datetime values has STRING result type MIN/MAX functions are asked
for a STRING value when the result is being sent to a client. The
Item_cache_datetime was designed to avoid conversions and get INT/STRING
values from an underlying item, but at the moment the values is asked
underlying item doesn't hold it anymore thus wrong result is returned.
Beside that MIN/MAX aggregate functions was wrongly initializing cached result
and this led to a wrong result.

The Item::has_compatible_context helper function is added. It checks whether
this and given items has the same comparison context or can be compared as
DATETIME values by Arg_comparator. The equality propagation optimization is
adjusted to take into account that items which being compared as DATETIME
can have different comparison contexts.
The Item_cache_datetime now converts cached INT value to a correct STRING
DATETIME value by means of number_to_datetime & my_TIME_to_str functions.
The Arg_comparator::set_cmp_context_for_datetime helper function is added. 
It sets comparison context of items being compared as DATETIMEs to INT if
items will be compared as longlong.
The Item_sum_hybrid::setup function now correctly initializes its result
value.
In order to avoid unnecessary conversions Item_sum_hybrid now states that it
can provide correct longlong value if the item being aggregated can do it
too.

Put '-features=no%except' back into Solaris/x86 CXXFLAGS.

This assert checks that the server does not try to send OK to the
client if there has been some error during processing. This is done
to make sure that the error is in fact sent to the client.

The problem was that view errors during processing of WHERE conditions
in UPDATE statements where not detected by the update code. It therefore
tried to send OK to the client, triggering the assert.
The bug was only noticeable in debug builds.

This patch fixes the problem by making sure that the update code
checks for errors during condition processing and acts accordingly.

Post-merge fix: remove leftovers from safemalloc removal.

of the "embedded" server

Problem: mysqltest_embedded failed to load ha_innodb_plugin library
on some platforms (due to some unresolved references).

Fix: on FreeBSD use -export-dynamic flag building mysqltest_embedded.
That allows to use its global symbols to resolve references in the
dynamically loaded plugin library.
