you the progress of inplace alter table and row log buffer usage

-    (x 100%, it's 4-digit. 10000 means 100.00%)
-    Innodb_onlineddl_rowlog_rows
       Shows how many rows are stored in row log buffer.
-    Innodb_onlineddl_rowlog_pct_used
       Shows row log buffer usage in percent ( *100%, it's 4-digit. 10000 means 100.00% ).
-    Innodb_onlineddl_pct_progress
       Shows the progress of inplace alter table. It might
       be not so accurate because inplace alter is highly
       depend on disk and buffer pool status.
       But still it is useful and better than nothing.

-    Add some log for inplace alter table
       XtraDB/InnoDB will print some message before and
       after doing some task.

Updated 33_scripts__mysql_create_system_tables__no_test.dpatch
to reflect user.default_role.

[re-commit in git]
Second variant of the fix: reduce the scope of 'role' variable

[Re-commit in git]
Don't check the value of 'role' variable in the cases where we don't need
it. (it may be marked as uninitialized and we get a runtime error).

The problem was that the internal temporary table created
for information_schema overflow to MyISAM because it has
a row width of > 3000 characters, which filled the in memory
temporary tables.
Fix was to increase size for the heap table.

result of innodb_sys_index test.

Fixed test failures seen on defragment tests, innodb.innodb-wl5522-debug-zip
and innodb.innodb_bug12902967.

SHOW COLUMNS and SHOW KEYS commands fill IS_table_read_plan
in a special way - they don't set or use lookup_field_vals
member.

Added a "trivial_show_command" flag that signals that
lookup_field_vals has no valid data, made EXPLAIN code honor it.

option.

When ORDER BY ... LIMIT check whether it should switch from index IDX1
to index IDX2, it should not ignore the fact that IDX2 may have a
potential range or ref(const) access.
Istead, it should calculate their costs: there is now a saved range
optimizer cost and code to re-calculate what best_access_path()
calculated for ref(const).

/* in current cost model these two can be very different
numbers unfortunately */

Let range optimizer remove parts of OR-clauses for which range analysis
produced SEL_TREE(IMPOSSIBLE).
There is no need to remove parts of AND-clauses: either they are inside
of OR (and the whole AND-clause will be removed), or the AND-clause is
at the top level, in which case the whole WHERE (or ON) is always FALSE
and this is a degenerate case which receives special treatment.

The removal process takes care not to produce 1-way ORs (in that case
we substitute the OR for its remaining member).

    Merged lp:maria/maria-10.0-galera up to revision 3880.

    Added a new functions to handler API to forcefully abort_transaction,
    producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
    were added for future possiblity to add more storage engines that
    could use galera replication.
