      WL#5331 Support Unicode for Windows command line client
      
      Based on the original patch form Vladislav Vaintroub:
      http://lists.mysql.com/commits/105379
      
      
        @ client/mysql.cc
        - introducing new function tee_write(), to reuse
          in a number of places where similar loops displaying
          data occurs.
        - introducing flags for tee_write(), to support different
          printing modes, according to --xml, --raw, --tab, etc,
          parameters
        - Instead if using argv (which is always in ANSI code page),
          we now use UTF16LE API to access command line arguments on Windows,
          using this scenario:
          a. We translate arguments to UTF8MB4 on startup.
          b. Then we process arguments and detect connection character set
             from --default-character-set arguments (or my.ini value),
             or from the OS localization information by default.
          c. Then we convert user, database and the --execute (-e) buffer
             from UTF8MB4 to the connection character set.
          d. Connect
        - Instead of printing using printif/fputs family functions on Windows,
          which are limited to the current DOS code page (cp850 on a Western machine)
          we now use UTF16LE console API through the new my_win_console_xxx() 
          functions implemented in my_conio.c
        - Using mysql_set_character_set() instead of
          mysql_option(OPT_CHARACTER_SET_NAME) to know the ongoing
          session character set *before* mysql_real_connect() call,
          to convert user and database properly.
        - my_win_is_console_cached() has been added to cache
          my_win_is_console() result for stdout and stderr,
          for performance purposes.
      
        @ client/mysqltest.cc
        - Introducing a new mysqltest command: --execw, to 
          execute commands with non-ASCII characters correctly in Windows.
      
      
        @ include/my_sys.h
        - Adding prototypes for the my_win_console_xxx() functions
      
        @ mysql-test/grant.test
        @ mysql-test/t/mysql.test
        @ mysql-test/t/mysql_cp932.test
        @ mysql-test/t/mysqlbinlog-cp932.test
        - Using --execw instead of --exec for the affected tests
      
        @ mysys/my_conio.c
        - Implementing functions for Windows console read/write and
          command line argument processing.
        - Removing my_cgets(), as it's not used any more.
      
        @ sql-common/client.c
        - Fixing mysql_set_character_set() to set mysql.charset on
          a non-connected "mysql". Previously such a call crashed.
          This change allows to know what character set for the
          ongoing session is going to be *before* calling mysql_real_connect().
          This is needed in mysql.cc, to convert user and database correctly
          on Windows.

No bundle (reason: useless for push emails).
