(Philip's review)

Take into account that services registered by  MySQL do not have
 .exe extension  in service binary path.

Problem: user without privileges can have an half-complete
installation, if he manages to click on "Ignore" for all  errors
in the installer. 

As a result, he will miss ARP registry keys, and uninstall 
will not be possible using  "Add/Remove Programs" applet.

on Win7 with the most strict user account control setting 
(secure desktop)

Fix: use job object for child process only, not for current
process itself.

* Spell username correctly as "NT AUTHORITY\NetworkService"
* Also, use well-known SIDs for predefined user when assigning directory
ACLs (the names differ in localized Windows)

The  general technique to generate MSI using CMake is taken from MySQL 5.5

Additional features not present in 5.5 installer : 
-optionally creating a new database
(as Windows service), using new mysql_install_db.exe to do the job
 
- optional upgrade of existing services from old MySQL or Maria installation.
This work is actually done by the upgrade wizard that is launched at the 
end of installation.

to uzpgrade existing MySQL/Maria services to higher version.

To be used in installer (but also can be used outside of installer too)

New utility to upgrade Windows service to higher MariaDB version.
Its functionality includes changing service definition as well as
running mysql_upgrade.

on Windows.

Some parameters not present in traditional mysql_install_db are present
e.g --port, --default-user (whether to create a new users) or 
--service (windows service name)

to be able to build MSI based installer

Fixes part of LP:705213 (Other part is to be pushed into 5.1)

storage/ndb/include/kernel/signaldata/FsOpenReq.hpp:
  Fixes compiler warnings
storage/ndb/include/ndbapi/NdbDictionary.hpp:
  Update to right typedef
storage/ndb/include/util/NdbSqlUtil.hpp:
  Remove not needed, conflicting code.
storage/ndb/src/kernel/blocks/dbtup/DbtupExecQuery.cpp:
  Added cast to get rid of not critical const.

sql/sql_base.cc:
  fill_record should be used for only one table (no need list).

support building with -all-static (no dlopen and dlclose make few
related declarations unused or "statement have no effect") and -Werror

don't pass NULL as an argument where va_list is expected.

Fixes failures in merge.test

Fix for LP#697610 ha_index_prev(uchar*): Assertion `inited==INDEX' failed with HANDLER + InnoDB in maria-5.3


mysql-test/suite/handler/innodb.result:
  Added test case
mysql-test/suite/handler/innodb.test:
  Added test case
sql/handler.h:
  Move setting/resetting of active_index to ha_index_init()/ha_index_end() to simplify handler functions index_init()/index_end()
  Fixed that get_index() returns MAX_KEY if index is not inited (this fixed LP#697610)
storage/federated/ha_federated.cc:
  Settting of active_index is not needed anymore
storage/maria/ma_pagecache.c:
  Added error message if we have too little memory for Maria page cache

storage/maria/ma_pagecache.c:
  - Ensure that we write also the last buffer in flush if buffer overflows.
  - Don't set PCBLOCK_IN_FLUSH if we don't flush the page
  - Added some new safety asserts.

Don't allow too low value of pagecache_buffer_size for mysqld

storage/maria/ha_maria.cc:
  Don't allow too low value of pagecache_buffer_size (as it will stop mysqld from starting)
storage/maria/maria_read_log.c:
  Allow one to decrease page-buffer-size down to 1M (from 128M)

storage/maria/maria_read_log.c:
  Allow smaller size for page-buffer-size (down to 1M)
  Sorted options for --help

storage/maria/ma_rsame.c:
  Fixed wrong test of index usage
storage/maria/ma_search.c:
  Fixed test to avoid compiler warnings.
  Safety fix to ensure that my_error is properly set in case of errors.

- Fix for MySQL BUG#52357 added NESTED_JOIN::is_fully_covered() which would 
  not take into account that MariaDB's table elimination could eliminate tables
  from join plan (and so, from join nest).
  Fixed the check in the function to compare post-table-elimination numbers.

- Set lastinx= ~0 when last_key.keyinfo is set.


storage/maria/ma_check.c:
  Set lastinx= ~0 when last_key.keyinfo is set
storage/maria/ma_ft_boolean_search.c:
  Set lastinx= ~0 when last_key.keyinfo is set
storage/maria/ma_rt_index.c:
  Remove setting of info->lastkey.keyinfo, as this should already be set by caller
storage/maria/ma_search.c:
  Added ASSERT to ensure that info->last_key.keyinfo is properly set
storage/maria/ma_unique.c:
   Set lastinx= ~0 when last_key.keyinfo is set

- Added test case for Aria
- Tested HANDLER with HEAP (changes to HEAP code will be pushed in 5.3)
- Moved all HANDLER test to suite/handler.


mysql-test/Makefile.am:
  Added suite/handler
mysql-test/mysql-test-run.pl:
  Added suite/handler
mysql-test/r/lock_multi.result:
  Remove test that is already in handler test suite
mysql-test/suite/handler/aria.result:
  Test for HANDLER with Aria storage engine
mysql-test/suite/handler/aria.test:
  Test for HANDLER with Aria storage engine
mysql-test/suite/handler/handler.inc:
  Extended the general handler test
  Moved interface testing to 'interface.test'
mysql-test/suite/handler/init.inc:
  Common init for handler tests.
mysql-test/suite/handler/innodb.result:
  New results
mysql-test/suite/handler/innodb.test:
  Update to use new include files

  New results
mysql-test/suite/handler/myisam.test:
  Update to use new include files
mysql-test/t/lock_multi.test:
  Remove test that is already in handler test suite
mysys/tree.c:

sql/handler.cc:
  Don't marka 'HA_ERR_RECORD_CHANGED' as fatal (can be used with HANDLER READ, especially with MEMORY ENGINE)
sql/handler.h:
  Added prototype for can_continue_handler_scan()
sql/sql_handler.cc:
  Re-initialize search if we switch from key to table search.
  Check if handler can continue searching between calls (via can_continue_handler_scan())
  Don't write common not fatal errors to log
storage/maria/ma_extra.c:
  Don't set index 0 as default. This forces call to ma_check_index() to set up index variables.
storage/maria/ma_ft_boolean_search.c:
  Ensure that info->last_key.keyinfo is set
storage/maria/ma_open.c:
  Don't set index 0 as default. This forces call to ma_check_index() to set up index variables.
storage/maria/ma_rkey.c:
  Trivial optimization
storage/maria/ma_rnext.c:

  Simple optimizations
storage/maria/ma_search.c:
  Initialize info->last_key once and for all when we change keys.
storage/maria/ma_unique.c:
  Ensure that info->last_key.keyinfo is up to date.
