DISTINCT wasn't optimized away and caused creation of tmp table in wrong
case. This result in integer overrun and running out of memory.
Fix backported from 4.1. Now if optimizer founds that in result be only 1
row it removes distinct.
sql/sql_select.cc:
Fix bug #13855 select distinct with group by caused server crash

field::sort_key() now adds length last for varbinary/blob
VARBINARY/BLOB is now sorted by filesort so that shorter strings comes before longer ones
Fixed issues in test cases from last merge
mysql-test/r/select.result:
Change column name in test to get GROUP BY to use the alias
mysql-test/r/type_blob.result:
Test BLOB and VARCHAR sorting
mysql-test/t/select.test:
Change column name in test to get GROUP BY to use the alias
Drop used tables at start of test
Don't use table names 'a', 'b' or 'c'
mysql-test/t/type_blob.test:
Test BLOB and VARCHAR sorting
sql/field.cc:
Store length last in VARBINARY() and BLOB() columns to get shorter strings sorted before longer onces
sql/field.h:
Added method 'sort_length()' to allow one to have length bytes last for VARBINARY/BLOB to get these to sort properly
sql/filesort.cc:
Use 'sort_length()' instead of 'pack_length()' to get length of field.
Store suffix_length last for varbinary (blob) objects.
The above ensures that BLOB/VARBINARY are correctly sorted (shorter strings before longer ones)
sql/sql_class.h:
Added sort suffix length (to get varbinary/blob to sort correctly)
sql/sql_select.cc:
Use sort_length() instead of pack_lengths()
strings/ctype-bin.c:
Don't let strnxfrm_bin store length last
Better to do it in MySQL field object to ensure it's done properly for all cases

The bug was in JOIN::join_free which was wrongly determining that
all joins have been already executed and therefore all used tables
can be closed.
mysql-test/r/subselect_innodb.result:
- test results fixed (Bug#12736 "Server crash during a select
mysql-test/t/subselect_innodb.test:
- a test case for Bug#12736 "Server crash during a select": test
that ha_index_or_rnd_end and mysql_unlock_tables are called
for all used tables in proper order.
sql/item_subselect.cc:
- implement subselect_union_engine::is_executed
sql/item_subselect.h:
- implement Item_subselect::is_evaluated. This function is used
to check whether we can clean up a non-correlated join of a subquery
when cleaning up the join of the outer query
sql/sql_lex.h:
- declare st_select_lex::cleanup_all_joins
sql/sql_select.cc:
- remove an argument from JOIN::join_free, it's now not used
- reimplement JOIN::join_free to not unlock tables if there
is a subquery that has not yet been evaluated. Make sure that the
new implementation calls ha_index_or_rnd_end for every table in
the join and inner joins, because all table cursors must be closed
before mysql_unlock_tables.
sql/sql_select.h:
- JOIN::join_free signature changed
sql/sql_union.cc:
- implement a helper method st_select_lex::cleanup_all_joins, which
recursively walks over a tree of joins and calls cleanup() for
each join.
Clean application of patch -
- Added --tz-utc to fix issue of dumping timestamp values between
servers with different global time zone settings, particularly
with regard to the day of DST changeover, which without this fix,
would dump duplicate timestamp values.
client/client_priv.h:
BUG# 13052 - clean application of http://lists.mysql.com/internals/30993
client/mysqldump.c:
BUG# 13052
Clean application of patch http://lists.mysql.com/internals/30993
- added new --tz-utc option
- added saving of TIME_ZONE in dump file
- set TIME_ZONE to "+00:00" in dump
mysql-test/r/mysqldump.result:
BUG# 13052 New results
mysql-test/t/mysqldump.test:
BUG# 13052
Added new test to test if the new option --tz-utc places
'SET TIME_ZONE="+00:00" at the top of the file and that this fixes
the problem of ending up with duplicate timestamp values that should
be unique on eve of DST
mysql-test/r/subselect.result:

sql/log_event.cc:
correcting bad manual merge. ZERO_LEN is not needed in 5.0, as ::exec_event() just tell()s the relay log instead
of using get_event_len().
sql/log_event.h:
get_event_len() is not needed in 5.0, ZERO_LEN neither.
sql/slave.cc:
fixes to take into account 5.0 specificities in replication. ZERO_LEN is not needed.
