Added storage/maria (based on MyISAM). WL#3245

Moved things into ft_global.h, my_handler.h and myisamchk.h to allow MyISAM and Maria to share code and defines
Rename of not properly renamed functions in MyISAM and my_handler.c
Renamed some MI_ defines to HA_ to allow MyISAM and Maria to share
Added maria variables to mysqld.cc and set_var.cc
Fixed compiler warnings
