- created binlog_encryption test suite and added it to the default list
- moved some tests from rpl, binlog and multisource suites to extra
so that they could be re-used in different suites
- made minor changes in include files

This bug is the result of merging the Oracle MySQL follow-up fix
BUG#22963169 MYSQL CRASHES ON CREATE FULLTEXT INDEX
without merging the base bug fix:
Bug#79475 Insert a token of 84 4-bytes chars into fts index causes
server crash.
Unlike the above mentioned fixes in MySQL, our fix will not change
the storage format of fulltext indexes in InnoDB or XtraDB
when a character encoding with mbmaxlen=2 or mbmaxlen=3
and the length of a word is between 128 and 84*mbmaxlen bytes.
The Oracle fix would allocate 2 length bytes for these cases.
Compatibility with other MySQL and MariaDB releases is ensured by
persisting the used maximum length in the SYS_COLUMNS table in the
InnoDB data dictionary.
This fix also removes some unnecessary strcmp() calls when checking
for the legacy default collation my_charset_latin1
(my_charset_latin1.name=="latin1_swedish_ci").
fts_create_one_index_table(): Store the actual length in bytes.
This metadata will be written to the SYS_COLUMNS table.
fts_zip_initialize(): Initialize only the first byte of the buffer.
Actually the code should not even care about this first byte, because
the length is set as 0.
FTX_MAX_WORD_LEN: Define as HA_FT_MAXCHARLEN * 4 aka 336 bytes,
not as 254 bytes.
row_merge_create_fts_sort_index(): Set the actual maximum length of the
column in bytes, similar to fts_create_one_index_table().
row_merge_fts_doc_tokenize(): Remove the redundant parameter word_dtype.
Use the actual maximum length of the column. Calculate the extra_size
in the same way as row_merge_buf_encode() does.
trx_state_eq(): Add the parameter bool relaxed=false, to
allow trx->state==TRX_STATE_NOT_STARTED where a different
state is expected, if an error has been reported.
trx_release_savepoint_for_mysql(): Pass relaxed=true to
trx_state_eq(). That is, allow the transaction to be idle
when ROLLBACK TO SAVEPOINT is attempted after an error
has been reported to the client.
- Used same fix as for MyISAM: High level collation byte stored in unused
bit_end position.
- Moved language from header to base_info
- Removed unused bit_end part in HA_KEY_SEG
Increase max number of possible table_open_cache instances from 512K
to 1024K. This only affects user who are trying to set the variable over
the old limit.
Delete not used test table_open_cache_instances_basic
(Need to be added back and rewritten in 10.2)
This occured when the SQL thread (but not the IO thread) stops while
GTID and parallel replication are used with multiple domain ids in the
GTID position, and is restarted.
In this case, the SQL needs to start some way back in the relay log,
applying or skipping events within each replication domain as
appropriate.
The SQL threads starts at the beginning of an old relay log file, and
this position may be in the middle of an event group. The bug was that
such partial event group could be re-applied, causing replication
corruption.
This patch fixes the issue, by making sure to skip any initial events
that were part of an earlier (already applied) event group.
Two problems:
(1) When pushing warning to sql-layer we need to check that thd != NULL
to avoid NULL-pointer reference.
(2) At tablespace key rotation if used key_id is not found from
encryption plugin tablespace should not be rotated.
Problem:-
The condition that checks for node readiness is too strict as it does
not allow SELECTs even if these selects do not access any tables.
For example,if we run
SELECT 1;
OR
SELECT @@max_allowed_packet;
Solution:-
We need not to report this error when all_tables(lex->query_tables)
is NULL:

TO MYSQL SERVER
Problem was that test innodb.innodb_stats_fetch_corrupted will post
a error InnoDB: Error: Table "mysql"."innodb_index_stats" not found
to a error log and test ignores that message. However, following tests
might see this error also and they might not ignore this error.
Force a server restart after innodb.innodb_stats_fetch_corrupted
to get clean log.
Analysis: By design InnoDB was reading first page of every .ibd file
at startup to find out is tablespace encrypted or not. This is
because tablespace could have been encrypted always, not
encrypted newer or encrypted based on configuration and this
information can be find realible only from first page of .ibd file.
Fix: Do not read first page of every .ibd file at startup. Instead
whenever tablespace is first time accedded we will read the first
page to find necessary information about tablespace encryption
status.
TODO: Add support for SYS_TABLEOPTIONS where all table options
encryption information included will be stored.
ENOTEMPTY is 247 on hppa, not 39 like on Linux, according to this report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=837369
So add another replacement for this to rpl.rpl_drop_db and
binlog.binlog_databasae tests (there were already a couple similar
replacements for other platforms).

When a deadlock kill is detected inside the storage engine, the kill
is not done immediately, to avoid calling back into the storage engine
kill_query method with various lock subsystem mutexes held. Instead the
kill is queued and done later by a slave background thread.
This patch in preparation for fixing TokuDB optimistic parallel
replication, as well as for removing locking hacks in InnoDB/XtraDB in
10.2.
