(caused maria.maria-preload.test to fail)

storage/maria/ma_loghandler.c:
  Fixed compiler warning
storage/maria/ma_pagecache.c:
  Added missing inc_counter_for_resize_op(pagecache).
  (caused maria.maria-preload.test to fail)

Fixed timing test failures.
Fixed a failure in the Aria engines page cache and log handler (found with maria.maria-big test)
- This could cause a core dump when deleting big blobs.
- Added test to end_pagecache() to verify that page cache was correctly used.
  - inc_counter_for_resize_op and dec_counter_for_resize_op are called same number of times.
  - All page cache blocks was properly deallocated (empty)

storage/maria/ma_loghandler.c:
  Fixed bug found by maria.maria-big test:
  - Fixed race condition between update thread logging a very big blog and checkpoint thread.
storage/maria/ma_pagecache.c:
  Added assert to ensure mutex was properly locked.
  Added test to end_pagecache() to verify that page cache was correctly used.
  - inc_counter_for_resize_op and dec_counter_for_resize_op are called same number of times.
  - All page cache blocks was properly deallocated (empty)
  In pagecache_delete_internal(), properly reset counters and pins if functions aborts.
  Added missing inc_counter_for_resize_op() to pagecache_wait_lock().
  Added missing dec_counter_for_resize_op() to pagecache_delete()

 - Make sure creation of t1 is replicated before trying to create trigger on it on slave
 - Use safe #ifdef for declaration as for definition to avoid warning about unused static function.

 
MTR_VS_CONFIG is now determined by looking at parent directory 
of sql\*\mysqld.exe,  instead of looking at *\*\BuildLog.htm

Reason : VS2010 does not create BuildLog.htm, hence prior method did not work.

  -  Remove all mentioning of /MAP /MAPINFO link options (does not work in VS2010).
     Remove map files from packaging.
  -  Fix warning about ETIMEDOUT being redefined.
  -  Fix  warning about FSP_EXTENT_SIZE in xtradb  (32/64 bit right shift mismatch)
  -  Silence warnings coming from  generated  code (flex/bison) in xtradb/innodb_plugin.
  -  Be nice to people without cygwin (me) and add win/configure-mariadb.bat with options suitable for quick compilation, e.g no embedded

An INSERT query log event is preceeded by an INSERT_ID intvar event if the
INSERT allocates a new auto_increment value. But if we ignore the INSERT
due to --replicate-ignore-table or similar, then the INSERT_ID event is
still executed, and the set value of INSERT_ID lingers around in the
slave sql thread THD object indefinitely until the next INSERT that
happens to need allocation of a new auto_increment value.

Normally this does not cause problems as such following INSERT would
normally come with its own INSERT_ID event. In this bug, the user had
a trigger on the slave which was missing on the master, and this
trigger had an INSERT which could be affected. In any case, it seems
better to not leave a stray INSERT_ID hanging around in the sql thread
THD indefinitely.

Note that events can also be skipped from apply_event_and_update_pos();
however it is not possible in that code to skip the INSERT without also
skipping the INSERT_ID event.

mysql-test/suite/innodb_plugin/t/innodb_bug56680.test:
  Disable test when run with valgrind as we get errors from buf_buddy_relocate() on work for this test.
  (Should probably be investigated as this may be an issue in xtradb, but probably harmless)
  Work is an amd-64 running openSUSE 1.11 and valgrind 3.4.1
mysys/charset.c:

Fix post-merge failure in 5.1-merge 
- Let QUICK_RANGE_INTERSECT_SELECT not make assumption that HA_EXTRA_KEYREAD 
  scans do not touch parts of table->record[0] that refer to fields that are 
  not covered by the used index.
  This assumption is not true for XtraDB (e.g. grep row/row0sel.c for 
  "init null bytes with default values as they might be").

Introduced a new flag in the class Item. The flag is set
to 1 only for items that are used in GROUP BY lists of
queries with ROLLUP.

Open issues:
- A better fix for #57688; Igor is working on this
- Test failure in index_merge_innodb.test ; Igor promised to look at this
- Some Innodb tests fails (need to merge with latest xtradb) ; Kristian promised to look at this.
 - Failing tests: innodb_plugin.innodb_bug56143 innodb_plugin.innodb_bug56632 innodb_plugin.innodb_bug56680 innodb_plugin.innodb_bug57255 
- Werror is disabled;  Should be enabled after merge with xtradb.
