the InnoDB Plugin tests are now in mysql-test/suite/innodb_plugin.

Move InnoDB tests to the innodb suite at mysql-test/suite/innodb.

This also instructs mtr to transparently load the plugin.

MySQL and InnoDB dictionaries do not get out of sync.

they are ignored to a new test suite "innodb_plugin".

Remove a hack in mtr that was deployed to run the builtin InnoDB tests against
the InnoDB Plugin. Also detect if a test is an 'innodb plugin test' and if so
then transparently replace the builtin InnoDB with the InnoDB Plugin.

    Bug #49838: DROP INDEX and ADD UNIQUE INDEX for same index may corrupt
       definition at engine
    
    If a single ALTER TABLE contains both DROP INDEX and ADD INDEX using 
    the same index name (a.k.a. index modification) we need to disable 
    in-place alter table because we can't ask the storage engine to have 
    two copies of the index with the same name even temporarily (if we 
    first do the ADD INDEX and then DROP INDEX) and we can't modify 
    indexes that are needed by e.g. foreign keys if we first do 
    DROP INDEX and then ADD INDEX.
    Fixed the problem by disabling in-place ALTER TABLE for these cases.

Stick to C90, because some build platforms are not C99 yet.

Fix ./export.sh to honor ENDREV

check that no index name starts with TEMP_INDEX_PREFIX.
