Post-merge patch to handle all the changes to the tree since the tree
was cloned.

Adding new fields Last_{IO,SQL}_Errno and Last_{IO,SQL}_Error to output
of SHOW SLAVE STATUS to hold errors from I/O and SQL thread respectively.
Old fields Last_Error and Last_Errno are aliases for Last_SQL_Error and
Last_SQL_Errno respectively.

Fields are added last to output of SHOW SLAVE STATUS to allow old applications
to use the same positional arguments into the row, while allowing new
application to benefit from the added information.

In addition, some new error codes are added (especially for the I/O
thread) to be able to provide sensible error message.

Third patch of the bug fix where the code for skipping events and for
executing events is factored out into three functions:
- shall_skip() to decide if the event shall be skipped and the
  reason for it;
- do_apply_event(), where the event is applied to the database; and
- do_update_pos(), which updates the actual relay log position and
  group positions.

The final testcase needing new error codes. Really.

Field_bit::set_default() did not check the bit_len, hence used the undefined
bit_ptr, causing a crash. The patch adds a check that bit_len > 0 before
following the bit_ptr.

Incorporating changes from review.
Fixing one bug that surfaced.

Added support for UPDATE.
Some minor fixes.

Extended replication to allow extra columns added last on slave
as compared with table on master.

This includes both code and test cases.
