Bug #49324: improved
Bug #51242/52336: reverted, applied a real fix.

Fix a couple of problems in the pack script, and disable a check feature that doesn't work right now

The statistics after a sequence of inserts/deletes are updated asynchronously
in PBXT, causing unpredictable test results. Fix by running the test on a
fresh copy of the table with no deletes performed, to get stable results.

Add a -nobuild argument to the script. Useful for building the zip file release with Express Edition which doesn't have the devenv command

mysql-test/suite/binlog/r/binlog_unsafe.result:
  Updated results (RAND() doesn't require statement based logging anymore for inserts)
mysql-test/t/information_schema_all_engines.test:
  Ensure that InnoDB is used

  (Failure can only happen for corrupted tables, but should be fixed properly at some point)

- INSERT with RAND() doesn't require row based logging again
- Some bugs fixed in opt_range() where we table->key_read was wrongly used



.bzrignore:
  Ignore new xtstat binary

  Added test for when RAND() requires row based logging
scripts/make_binary_distribution.sh:
  Removed type from last commit
sql/item_create.cc:
  Don't require row based logging when using RAND() with INSERT
sql/opt_range.cc:
  Revert wrong patch from Oracle:
  - As QUICK_RANGE_SELECT uses it's own 'file' handler to the tables, one can't use 'table->key_read' as a flag to detect if index only read (keyread) is used or not
  - Don't set keyread if keyread is already enabled
  - Don't disable key read, if we didn't enable it ourselves
  - Simplify code (and ensure that we do proper cleanup of index only read)
sql/opt_range.h:
  Added flags to detect if the range optimizer enabled index only read (key read) or not
sql/opt_sum.cc:
  Use our more optimized macros
sql/sql_lex.h:
  Added 'readable' function to check if we are in a sub query function or not (not normal query or sub query in FROM clause)
sql/sql_select.cc:
  Use our more optimized keyread macros
  Added ASSERTS early
  Simplify code on eliminate_item_equal()
  Fixed that substitute_for_best_equal_field() doesn't core dump in case of out of memory conditions.
  Removed not needed test for 'field->maybe_null()'
  Replaced master_unit()->item with is_subquery_function() (More readable)
sql/sql_update.cc:
  Use our more optimized keyread macros
sql/table.cc:
  Use our more optimized keyread macros
sql/table.h:
  Use separate functions to enable/disable Index only reads
  - Safer, more readable, better logging and faster.

scripts/make_binary_distribution.sh:
  Added copying of xstat
scripts/make_win_bin_dist:
  Added copying of xstat

Result file update for main.subselect (the MySQL 5.1.46 version has buggy output in the .result, see BUG#47904 comments).

Cherry-pick fix for Bug#53371, security hole with bypassing grants using special path in db/table names.
Bump MariaDB version for security fix release.
