currently Fusion-io SSD drive does not support setting file
size without fysically writing pages with zeroes when fallocate
with PUCH_HOLE is used.
Added additional error message if atomic write setup does not
succeed.
Applied a patch from Philip Hazel implementing the non-standard
syntax for word boundaries in PCRE, for compatibility with the
old Henry Spencer's regex library.

Analysis: In earlier MySQL 5.6 versions this table innodb_index_stats used to have a foreign key referencing to innodb_table_stats. However, in newer MySQL 5.6 versions this foreign key is removed and if you upgrade, your innodb_table_stats is created by the earlier mariadb version, thus a newer version will complain that the table is incorrectly defined.
Added drop foreign key on mysql_system_tables_fix.sql to be executed on mysql_upgrade.
Fixed the following compilation errors and test failures:
- maria SE: "stage_waiting_for_a_resource" wasn't declared w/o PFS
- sql_repl.h: PSI_mutex_key is not available in non-PFS builds
- mysqld.cc: pfs_param is not available in non-PFS builds
- mysqld.cc: init_show_explain_psi_keys() is not available in non-PFS builds
- mysqld.cc: call net_before_header_psi, net_after_header_psi even if PFS
is not available so that thread enters stage_init at proper time. Fixes
sp-threads and a few tests in funcs_1.
- myisam_file_io.opt: added missing loose prefix
restore old innodb get_innobase_type_from_mysql_type() function,
record all mysql_type->innodb_type mapping
(as generated by mysql-5.6).
add safety code to disable online alter when internal types don't match
storage/innobase/dict/dict0stats.cc:
revert to 5.6 state
Apply fix suggested by Igor:
- When eliminate_item_equal() generates pair-wise equalities from a
multi-equality, do generate a "bridge" equality between the first
field inside SJM nest and the field that's first in the overall multi-equality.
and MYSQL CONNECT tables to take care of kewords such as IGNORE.

When setting Item_func_not_all::test_sum_item or Item_func_not_all::test_sub_item,
reset the other one to NULL - they can never be set both. When a PS is reexecuted,
different executions might be optimized differently and a wrong test_su*_item
might stay set from the previous execution.
- MIN/MAX optimizer does a check whether a "field CMP const" comparison uses a constant
that's longer than the field it is compared to. Make this check only for string columns,
also compare character lengths, not byte lengths.
1. Transformation of row IN subquery made the same as single value.
2. replace_where_subcondition() made working on several layers of OR/AND because it called on expression before fix_fields().
(and valgrind warnings)
* move thd userstat initialization to the same function
that was adding thd userstat to global counters.
* initialize thd->start_bytes_received in THD::init
(when thd->userstat_running is set)
Singular Item_equal support added.
The problem was that during constant table substitution Item_equal become containing only one constant which was not supported internally.
A clean-up: removing the code catching collation incompatibilities
from handler::check_collation_compatibility(), as the collation IDs
are already replaced at this point by TABLE_SHARE::init_from_binary_frm_image.
