replaced snippets_udf.cc with the latest version (2.0.8 from sphinxsource.com), fixed trivial errors on Windows.
It will be compiled and installed into plugins directory now.

    Fixing not to use default_character_set->state_map,

  - Fixed that wait_timeout_func and wait_timeout tests works on solaris
  - We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO).
  - Fixed that compile-solaris-amd64-debug works (before that we got a wrong ELF class: ELFCLASS64 on linkage)
- Fixed some compiler warnings
- Fixed some failing tests

        get_mm_leaf function can store all sorts of spatial features in

(The problem is that if $USER is root, then the authentication will log
in with the mysqld user root. And then CURRENT_USER() returns a valid
user, giving .result file difference).

MDEV-4514 After increasing user name length mysql.db is reported broken and event scheduler does not start

because --log-bin sets opt_bin_logname to ""
(same for any OPT_ARG GET_STR (or GET_STR_ALLOC) option)

to match distribution packages better:
  remove "mysql" from server.rpm Provides, add it to the shared.rpm Provides.
  fake provides that "mysql" and "mysql-libs" packages would've had.

cleanup:
  remove auto-generated provides from the manual provides list.

Fixed MDEV-4291: Assertion `trid >= info->s->state.create_trid' failure or data corruption (key points to record
outside datafile) on INSERT into an Aria table.

The isssue was that the check if a table was moved between systems didn't take into account that create_trid could be bigger than the current max trid on the new system.
This could only happen if one tried to move a table that one had just done a 'REPAIR TABLE' on.
Tables that one had run 'aria_chk --zerofill' on worked.

Fixed this by assuming that if create_trid is too big then the table has been moved from one system to another and we have to do an automatic zerofill.

Other fixed:

- Added a check to detect a wrong create_trid in 'check table'.
- aria_chk -dvv will now write out also the create_trid (to make future error finding easier)
- aria_chk --zerofill doesn't anymore require a aria_control_file
- Removed some warnings from safemalloc when using aria_chk, ma_test1 and ma_test2.


include/myisamchk.h:
  Removed wrong 'QQ' flags (the flags are used by myisamchk and aria_chk)
storage/maria/ha_maria.cc:
  maria_chk_status() can now also return an error.
storage/maria/ma_check.c:
  In maria_chk_status() check if create_trid value is too big.
storage/maria/ma_open.c:
  Changed check if table is moved so that we can detect wrong create_trid values.
  Don't set STATE_NOT_MOVABLE flag if we are doing repair/check. This was done so that aria_chk can print out the movable flag.
storage/maria/ma_test1.c:

MDEV-3999: Valgrind errors 'invalid write' or assorted server crashes on concurrent flow with partitioned Aria tables
MDEV-3989: Server crashes on import from MariaDB mysqldump export with partitioned Aria table.

Problem was that bulk insert in aria was not properly protected against concurrent selects.


storage/maria/ha_maria.cc:
  Move settings of file->state to _ma_block_start_trans() to ensure that lock_key_trees is not changed by a concurrent bulk_insert.
storage/maria/ma_check.c:
  Added DBUG_ASSERT()
storage/maria/ma_open.c:
  Set start_trans to ma_start_trans for default behaviour.
storage/maria/ma_pagecrc.c:
  Removed test for 'non_transactional' as a now_transactinal could be reset while a flush was happening.
storage/maria/ma_state.c:
  Moved setting of info->state from external_lock to start_trans to protect against concurrent running bulk inserts.
  This works as the other threads will wait in thr_lock() until bulk_insert is done and keys are re-generated.
storage/maria/ma_state.h:
  Added _ma_start_trans()

Fixed that SHOW PROCESSLIST and information_schema.processlist uses the right length for user names.

MDEV-4280: Assertion `empty_size == empty_size_on_page' failure in ma_blockrec.c or ER_NOT_KEYFILE on query with DISTINCT and GROUP BY
This could happen when using Aria for internal temporary files (default case) and using DISTINCT.
_ma_scan_restore_block_record() didn't work correctly if there was rows inserted, updated or deleted on the handler
between calls to _ma_scan_remember_block_record() and _ma_scan_restore_block_record().
The effect was that some DISTINCT queries that used remove_dup_with_compare() could fail.

  Test case for MDEV-4280

storage/maria/ha_maria.cc:
  scan_restore_pos() can return disk fault error.
storage/maria/ma_blockrec.c:
  _ma_scan_remember_block_record() did incorrectly update scan.dir instead of scan_save.dir .
  _ma_scan_restore_block_record() didn't work correctly if there was rows inserted,updated or deleted on the handler
  between calls to _ma_scan_remember_block_record() and _ma_scan_restore_block_record().
  Fixed by adding counters for row changes and reading the current scan page if changes had been made.

  scan_restore_pos() can return disk fault error.
storage/maria/ma_delete.c:
  Increment row_changes

  scan_restore_pos() can return disk fault error.

Added comment to clearify the code.


storage/maria/ma_blockrec.c:
  Added comment to clearify the code
  In case of out of memory or disk error, mark pages with LSN_IMPOSSIBLE to make it easier to know which pages have wrong information.

- Use lc-messages-dir instead of deprecated --language when running mysqld in bootstrap mode.
- Add some verbosity to mysql_install_db.exe when it runs in course of MSI installation.

avoid divison by zero

MDEV-4489 "Replication of big5, cp932, gbk, sjis strings makes wrong values on slave"
has been fixed.

Problem:
String constants of some Asian charsets (big5,cp932,gbk,sjis)
can have backslash '\' (0x5C) in the second byte of multi-byte characters.
Replicating of such constants using the standard '\'-escaping is dangerous.
Therefore, constants of these charsets are replicated using hex notation:
INSERT INTO t1 (a) VALUES (0x815C);

However, 0xHHHH constants do not work well in some cases,
because they can behave as strings and as numbers, depending on context
(for example, depending on the data type of the column in an INSERT statement).

This SQL script was not replicated correctly with statement-based replication:

SET NAMES gbk;
PREPARE STMT FROM 'INSERT INTO t1 (a) VALUES (?)';
SET @A = '1';
EXECUTE STMT USING @A;

The INSERT statement was replicated as:
INSERT INTO t1 (a) VALUES (0x31);

'1' was correctly converted to the number 1 on master.
But the 0x31 constant was treated as number 49 on slave.

Fix:

1. Binary log now uses X'HHHH' instead of 0xHHHH constants.
2. The X'HHHH' constants now work always as strings, in all contexts.
This is the SQL standard compliant behaviour.

After the fix, the above statement is replicated as:
INSERT INTO t1 (a) VALUES (X'31');
X'31' is treated as string '1' on slave, and is correctly converted to 1.
