Tail fixes after re-applying patches to older version of clone.

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.

Second patch to fix skipping code. Moving relay and binary log 
position changing code from do_apply_event [old exec_event()] into
do_update_pos() and doing other changes necessary to support that.

Fixing a bug that can cause deadlock if rotating binary log when committing
a changes to a transactional table that is not inside a transaction and
cause a rotate log.

Changes to the code are necessary to compile on Windows. Typecasts are needed in several DBUG_DUMP statements. CAB 01 Nov 2006

BUG#23735 Test rpl_row_mysqlbinlog fails on Windows. The errors report a file discrepency on reading a binlog from the command line.

First patch preparing for restructuring the event execution and event
skipping. This patch renames the existing (virtual) function exec_event()
to be a primitive for implementing the real patch. Also, the virtual function
advance_coord_impl() is added to advance the binary/relay log coordinates,
and two non-virtual functions exec_event() [sic] and skip_event() is added
that will contain the business logic for executing and skipping events
respectively.

Not replicating the mysql database *at all* any more. All changes to
mysql tables are replicated by replicating the statements that do
the changes.

sync using replicate-wild-ignore-table
Problem: changes in character set variables
before an action on an replication-ignored table
makes slave to forget new variable values.
Fix: initialize one_shot variables only when
4.1 -> 5.x replication is running.

make code easier to maintain.

should be a separate module (i.e. a class) to make it easier to maintain the 
code, e.g. by having checks within the rli checking sanity of data and making 
member variables private.  This will also ease implementation of multi-source 
and, at least in my fantasies :), make it possible in some future to have 
separate replication servers.

  Problem: SHOW CREATE TABLE printed garbage in table
  name for tables having TURKISH I
  (i.e. LATIN CAPITABLE LETTER I WITH DOT ABOVE)
  when lower-case-table-name=1.
  
  Reason: In some cases during lower/upper conversion in utf8,
  the result string can be shorter the original string
  (including the above letter). Old implementation of caseup_str()
  and casedn_str() didn't handle the result length properly,
  assuming that length cannot change.
  
  This fix changes the result type of cs->cset->casedn_str()
  and cs->cset->caseup_str() from VOID to UINT, to return
  the result length, as well as put '\0' terminator on a 
  proper place.
  
  Also, my_caseup_str_utf8() and my_casedn_str_utf8() were 
  rewritten not to use strlen() for performance purposes.
  It was done with help of adding of new functions - my_utf8_uni_no_range()
  and my_uni_utf8_no_range() - for null terminated strings.

Problem: Too confusing error message when cannot convert
between string and column character sets on INSERT and UPDATE.
Fix: producing a better error message, instead of "Data too long"
in such cases
Additional changes: Adding "DROP TABLE IF EXISTS" into several
tests to be safe against failures in previous tests.

Fix: swap arguments to eq_func() and eq_func_reverse() to provide correct operation result.
