  fix for .deb and .rpm installations

 - use thd->in_active_multi_stmt_transaction() for
   @@in_transaction, not THD flag directly
 - use common error_if_in_trans_or_substatement() function for
   all 4 binlog variables that cannot be changed inside
   statement or transaction.

This bug appeared after the patch for bug 939009 that in the
function merge_key_fields forgot to reset a proper value for
the val field in the result of the merge operation of the key
field created for a regular key access and  the key field
created to look for a NULL key.

Adjusted the results of the test case for bug 939009 that
actually were incorrect. 

Otherwise XA crashes after FLUSH STATUS as log page size suddenly becomes 0.

make sure that stored routines are evaluated (that is, de facto - cached) in convert_const_to_int().
revert the fix for lp:806943 because it cannot be repeated anymore.
add few tests for convert_const_to_int()

The issue was that Aria allowed too long keys to be created (so that the internal buffer was not big enough to hold the whole key).
Key lengths is now limited to HA_MAX_KEY_LENGTH (1000), as for MyISAM.
Fixed failure in  "_ma_apply_redo_index: Assertion `new_page_length == 0", as found by buildbot.

  Updated results. Added test for bug fix

mysql-test/suite/maria/t/optimize.test:
  Updated test for new max key length
storage/maria/ha_maria.cc:
  Limit key to HA_MAX_KEY_LENGTH.
storage/maria/ma_key_recover.c:
  Limit used page length to max page size (this is in line with the code that writes the entry to the log).
  This fixes failure in  "_ma_apply_redo_index: Assertion `new_page_length == 0", as found by buildbot.
storage/maria/ma_search.c:
  Extra DBUG
storage/maria/ma_write.c:
  Added test to detect errors earlier.

because of the high cost associated with  fake symdir resolution, disable symbolic-links on Windows by default. Real symlinks (Vista+) as well as NTFS junctions (prior to Vista) do not require this parameter

A better fix for this bug will be pulled from mariadb-5.2.

The field key_cache_mem_size of the KEY_CACHE structure must be
initialized in the function init_key_cache() and updated in the
function resize_key_cache().

Cause of the bug is uninitialized items before evaluation HAVING clasue in case of empty result.

The result of materialization of the right part of an IN subquery predicate
is placed into a temporary table. Each row of the materialized table is
distinct. A unique key over all fields of the temporary table is defined and
created. It allows to perform key look-ups into the table.
The table created for a materialized subquery can be accessed by key as
any other table. The function best_access-path search for the best access
to join a table to a given partial join. With some where conditions this
function considers a possibility of a ref_or_null access. If such access
employs the unique key on the temporary table then when estimating
the cost this access the function tries to use the array rec_per_key. Yet,
such array is not built for this unique key. This causes a crash of the server.

Rows returned by the subquery that contain nulls don't have to be placed
into temporary table, as they cannot be match any row produced by the
left part of the subquery predicate. So all fields of the temporary table
can be defined as non-nullable. In this case any ref_or_null access
to the temporary table does not make any sense and it does not make sense
to estimate such an access.

The fix makes sure that the temporary table for a materialized IN subquery
is defined with columns that are all non-nullable. The also ensures that 
any row with nulls returned by the subquery is not placed into the
temporary table.  

- Enable subquery materialization for CREATE TABLE ... SELECT.
