Move Aria-only HA_RTREE_INDEX from my_base.h to maria_def.h (breaks an assert in InnoDB)
Fix InnoDB memory leak
Fixed "check of testcases" failure.
Value of INFORMATION_SCHEMA.PLUGINS.PLUGIN_TYPE_VERSION was
pointing to incorrect address and could change after server
restart.
storage/innobase/handler/i_s.cc:
Use proper plugin info pointer (struct st_mysql_information_schema
instead of ST_FIELD_INFO[]).
i_s_innodb_buffer_page_get_info(): Do not read the buffer block frame
contents of read-fixed blocks, because it may be invalid or
uninitialized. When we are going to decompress or read a block, we
will put it into buf_pool->page_hash and buf_pool->LRU, read-fix the
block and release the mutexes for the duration of the reading or
decompression.

== Analysis ==
Both change buffer pages and on-disk indexes pages are marked as
FIL_PAGE_INDEX. So all ibuf index pages will classify as INDEX with NULL
table_name and index_name.
== Solution ==
A new page type for ibuf data pages named I_S_PAGE_TYPE_IBUF is defined. All
these pages whose index_id equal (DICT_IBUF_ID_MIN + IBUF_SPACE_ID) will
classify as IBUF_DATA instead of INDEX in INNODB_BUFFER_PAGE
and INNODB_BUFFER_PAGE_LRU.
This fix is only for IS reporting, both on-disk and buffer pool structures
keep unchanged.

WITH --SKIP-INNODB
Description
-----------
If the server is started with skip-innodb or InnoDB otherwise fails to
start, any one of these queries will crash the server:
For (5.5)
SELECT * FROM INFORMATION_SCHEMA.INNODB_BUFFER_PAGE;
SELECT * FROM INFORMATION_SCHEMA.INNODB_BUFFER_PAGE_LRU;
SELECT * FROM INFORMATION_SCHEMA.INNODB_BUFFER_POOL_STATS;
In (5.6+) ,following queries will also crash the server.
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_TABLES;
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_INDEXES;
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_COLUMNS;
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_FIELDS;
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_FOREIGN;
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_FOREIGN_COLS;
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_TABLESTATS;
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_DATAFILES;
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_TABLESPACES;
FIX
----
When Innodb is not active we must prevent it from processing
these tables,so we return a warning saying that innodb is not
active.
