Manual merge 5.0->5.1. Post-merge fixes.

client/mysqldump.c:
  A post-merge fix - 'sock' was renamed to 'mysql'
mysql-test/r/events_bugs.result:
  A post merge fix: now we strip rear comments from the query before
  it gets into the log.
mysql-test/r/func_group.result:
  A post merge fix: default clause is now printed uppercase.
mysql-test/r/im_life_cycle.result:
  Fix my mistake in manual resolve.
mysql-test/r/mysqlcheck.result:
  use test; - after we drop client_test_db there is no current database.
  This cleanup is present in 5.1 only, but the test that was added in 
  5.0 assumes there is a current database, test.
mysql-test/r/mysqldump.result:
  Ignore results of execution of mysqldump: we can't rely on 
  MASTER_LOG_POS in test results, it's different for statement
  and row level logging.
mysql-test/r/mysqlshow.result:
  A post-merge fix: information schema contains a few more tables
  in 5.1
mysql-test/r/mysqltest.result:
  A post merge fix: add 5.1 test end separator.
mysql-test/r/ndb_basic.result:
  A post-merge fix: add test end separators.
mysql-test/r/rpl_switch_stm_row_mixed.result:
  A post merge fix: length of varbinary column is now 3 times less.
  Assuming a side effect of some other change. Length of any
  field is not relevant in this test.
mysql-test/r/rpl_view.result:
  Add an end of test marker.
mysql-test/r/show_check.result:
  Remove duplicate results. Add results from a merged test case.
mysql-test/r/sp-error.result:
  Add test end separators.
mysql-test/r/sp-security.result:
  Post-merge fix: use test after the current database is dropped.
mysql-test/r/sp.result:
  Remove a duplicate result (bad merge that left a copy of
  the test case for Bug#19862 in the test suite).
mysql-test/r/strict.result:
  An after-merge fix for a new test case: in 5.1 we issue a more accurate
  error message: "Incorrect value" instead of "Truncated value". I reason
  it so that in case of an error nothing is truncated, really.
  Also found similar changes in other test cases.
mysql-test/r/type_datetime.result:
  Fix the text of an error.
mysql-test/r/union.result:
  A post-merge fix: CHARACTER SET is now uppercase.
mysql-test/t/mysqlcheck.test:
  A post-merge fix: use test, after current database is dropped, there
  is no current database.
mysql-test/t/mysqldump.test:
  Disable result log: it's dependent on binlog position.
mysql-test/t/sp-security.test:
  use test
sql/item_sum.cc:
  Adjust the call to the constructor after the merge.
sql/sp_head.cc:
  Add a missing DBUG_VOID_RETURN, move security checks out of
  execute_trigger to Table_triggers_list: in 5.1 we check for
  TRIGGER privilege, not SUPER privilege to execute triggers, so these
  checks lack table context inside execute_trigger and have to be
  performed when we have table object on hand.
sql/sql_db.cc:
  A post-merge fix: adjust load_db_opt_by_name and check_db_dir_existence
  (new functions added in 5.0) to be tablename-to-filename encoding 
  friendly.
sql/sql_lex.cc:
  A post-merge fix: make skip_rear_comments operate on const uchar *s.
sql/sql_lex.h:
  A post-merge fix.
sql/sql_show.cc:
  A post-merge fix: fix a bad merge, rename orig_sql_command -> sql_command.
sql/sql_trigger.cc:
  A post-merge fix: move security checks to process_triggers
  from execute_trigger.
sql/sql_view.cc:
  Adjust to the new signature of skip_rear_comments.
sql/sql_yacc.yy:
  Adjust to the new signature of init_strings.
