Monty 2dbeebdb16 Changed static const in Alter_info and Alter_online_info to defines
Main reason was to make it easier to print the above structures in
a debugger. Additional benefits is that I was able to use same
defines for both structures, which simplifes some code.

Most of the code is just removing Alter_info:: and Alter_inplace_info::
from alter table flags.

Following renames was done:
HA_ALTER_FLAGS        -> alter_table_operations
CHANGE_CREATE_OPTION  -> ALTER_CHANGE_CREATE_OPTION
Alter_info::ADD_INDEX -> ALTER_ADD_INDEX
DROP_INDEX            -> ALTER_DROP_INDEX
ADD_UNIQUE_INDEX      -> ALTER_ADD_UNIQUE_INDEX
DROP_UNIQUE_INDEx     -> ALTER_DROP_UNIQUE_INDEX
ADD_PK_INDEX          -> ALTER_ADD_PK_INDEX
DROP_PK_INDEX         -> ALTER_DROP_PK_INDEX
Alter_info:ALTER_ADD_COLUMN    -> ALTER_PARSE_ADD_COLUMN
Alter_info:ALTER_DROP_COLUMN   -> ALTER_PARSE_DROP_COLUMN
Alter_inplace_info::ADD_INDEX  -> ALTER_ADD_NON_UNIQUE_NON_PRIM_INDEX
Alter_inplace_info::DROP_INDEX -> ALTER_DROP_NON_UNIQUE_NON_PRIM_INDEX

Other things:
- Added typedef alter_table_operatons for alter table flags
- DROP CHECK CONSTRAINT can now be done online
- Added checks for Aria tables in alter_table_online.test
- alter_table_flags now takes an ulonglong as argument.
- Don't support online operations if checksum option is used.
- sql_lex.cc doesn't add ALTER_ADD_INDEX if index is not created

VERSION

MariaDB: drop-in replacement for MySQL

MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.

MariaDB is brought to you by the MariaDB Foundation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.

MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Foundation and the MariaDB Corporation, and by many people in the community.

MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.

A description of the MariaDB project and a manual can be found at: https://mariadb.org/ https://mariadb.com/kb/en/ https://mariadb.com/kb/en/mariadb-vs-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/

As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable.
