- merge_same_index_scans() may put the same SEL_ARG tree in multiple result plans.
  make it call incr_refs() on the SEL_ARG trees that it does key_or() on, because 
  key_or(sel_arg_tree_1, sel_arg_tree_2) call may invalidate SEL_ARG trees pointed 
  by sel_arg_tree_1 and sel_arg_tree_2.

MDEV-4643 MariaDB crashes consistently when trying a SELECT on VIEW with a UNION and an additional JOIN in SELECT

remove emtpty Item_func_match::update_used_tables() method

Fix of nested join parsing of illegal query.

Cleanup: remove TIME_FUZZY_DATE.

Introduce TIME_FUZZY_DATES which means "very fuzzy, the resulting
value is only used for comparison. It can be invalid date, fine, as long as it can be
compared".

Updated many tests results (they're better now).

for field terminators, uchar was compared with char

Item_func_min_max::get_date() did not check the
returned value against the fuzzy_date flags, so
it could return a bad value to the caller that
expects a good date (e.h. CONVERT_TZ).

Do not use x64  assembler implementation in  x32.

fix the code to compile w/o perfomance schema

Also, fixing a bug in STR_TO_DATE(). It erroneously returned
error in strict mode for dates like '0000-01-01'
(zero year, but non-zero month and day).

According to the manual:
- NO_ZERO_DATE disallows 0000-00-00 (all date parts are zeros)
- NO_ZERO_IN_DATE disallows zero month (YYYY-00-DD) or day (YYYY-MM-00).

0000-01-01 is a valid date, even in strict mode.

See also MySQL Bug #39750  and similar ones.

Fix my_delete() on Windows, to safely remvoe files on Windows, including files  that are opened by another threads in the same process, antiviruses and  backup applications. If file to be deleted is  also  opened by another thread, the file is renamed to unique name prior to deletion - this makes it possible to create file with the same name right after deletion.
With this patch my_delete_allow_opened() becomes obsolete and is replaced with my_delete().

This patch is rework of the patch  http://lists.mysql.com/commits/59327  for MySQL bug#39750.

Non-blocking client currently can be build on Windows, GCC on i386 and x64, or any OS wth ucontext.h header. Prior to this patch, build failed if neither of these conditions is true.
Fix to avoid compiler errors in these case - non-blocking API would not be useful on , but otherwise everything will work as before.

Partitioning didn't store the name of default storage engine for partitions
in the frm file - it only store the typecode. Typecodes aren't stable, and
might vary depending on the order in which storage engines are loaded (can
be changed even from my.cnf without recompilation).

As a temporary workaround for 5.5, we hard-code Aria's typecode, to make sure it
never changes.

Add mysql_plugin.1 from mysql-5.5.30.tar.gz

processlist has started. Don't show a negative or huge wrapped-around query execution time.
