Fixed some varnings from valgrind

Set min value of max_allowed_packet to 1024
Fixed problem with UNION's without braces and SQL_CALC_FOUND_ROWS, LIMIT #,#
and ORDER BY...LIMIT


include/m_string.h:
  Added memcpy_overlap() to avoid warnings when using valgrind on memcpy(A,A,...)
myisam/mi_create.c:
  Fixed comment
myisam/mi_search.c:
  Fix warning from valgrind
myisam/mi_write.c:
  Indentation fix
mysql-test/mysql-test-run.sh:
  Add options handled by general skip- option
mysql-test/r/packet.result:
  Update results after change to mysqld (min max_allowed_packet length is now 1024)
mysql-test/r/union.result:
  Added testing of UNION with SQL_CALC_FOUND_ROWS
mysql-test/t/packet.test:
  Update results after change to mysqld (min max_allowed_packet length is now 1024)
mysql-test/t/union.test:
  Added testing of UNION with SQL_CALC_FOUND_ROWS
sql/field.cc:
  Fix to remove waarning from valgrind
sql/ha_innodb.cc:
  Remove wrong include file
sql/item_cmpfunc.cc:
  Safety fix to handle EOM conditions in IN
sql/item_sum.cc:
  Fixed prototype for update_field() (argument was alwys 0)
sql/item_sum.h:
  Fixed prototype for update_field() (argument was alwys 0)
sql/item_uniq.h:
  Fixed prototype for update_field() (argument was alwys 0)
sql/log.cc:
  Indentation fix
sql/mysqld.cc:
  Set min value of max_allowed_packet to 1024 (to avoid it getting set to 0)
sql/net_serv.cc:
  Indentation changes + trivial optimization
sql/sql_select.cc:
  Fixed prototype for update_field() (argument was alwys 0)
sql/sql_union.cc:
  Fixed problem with UNION's without braces and
  - SQL_CALC_FOUND_ROWS
  - LIMIT #,#
