        MWL#17: Table elimination
        - Move eliminate_tables() to before constant table detection, this will allow
          to spare const table reads (at a cost of not being able to take advantage of 
          tables that are constant because they have no records, but this case is of 
          lesser importance)

      - Fix print_join() to work both for EXPLAIN EXTENDED (after table elimination) and for 
        CREATE VIEW (after join->prepare() but without any optimization).

      - Fix the previous cset: take into account that select_lex may be printed when 
       1. There is no select_lex->join at all (in that case, assume that no tables were eliminated)
       2. select_lex->join exists but there was no JOIN::optimize() call yet. handle this by initializing join->eliminated really early.

      - Make elimination work with aggregate functions. The problem was that aggregate functions 
        reported all table bits in used_tables(), and that prevented table elimination. Fixed by 
        making aggregate functions return more correct value from used_tables(). 
      
      mysql-test/r/ps_11bugs.result:
        MWL#17: Table elimination
        - Update test results. The difference is because of Item_ref change: outer references to constants
          are now recognized as constants, too.
      mysql-test/r/subselect.result:
        - Update test results. The difference is because of Item_ref change: outer references to constants

        - Check that elimination works in presense of aggreagate functions
      sql/item.h:
        MWL#17: Table elimination
        - Add Item_ref::const_item() which calls (*ref)->const_item(). Before this diff Item_ref used the 
          default implementation of const_item(){ return used_tables()==0; }. This is no longer true, as 
          COUNT(*) now has used_tables()==0 but const_item()==FALSE.
      sql/item_sum.cc:
        MWL#17: Table elimination
        - Make Item_sum() and it descendants not to return all bits in used_tables(). This is needed 
          because otherwise table elimination can't work in presense of aggregate functions
        - COUNT(*) now has used_tables()==0 and const_item()==FALSE. Had to change 
          Item_ref::const_item() to account for this.

      - First code. Elimination works for simple cases, passes the testsuite.
      - Known issues:
        = No elimination is done for aggregate functions.
        = EXPLAIN EXTENDED shows eliminated tables (I think it better not)
        = No benchmark yet
        = The code needs some polishing.

      We are now using Valgrind rather than purify, and have for quite some time. · b125770a
      unknown authored
      Consequently, rename HAVE_purify to HAVE_valgrind, and related changes.
      Leave some comments about purify when not clear that they apply also to Valgrind.
      Fix redundant IF_VALGRIND declaration.
      
      Misc. small fixes:
       - Fixes for pool-of-threads patch.
       - Fixes for push of PBXT storage engine.
       - mysql-test-run.pl fix.
       - Fix build problem in compile-pentium64-max.
      
      
      BUILD/SETUP.sh:
        Rename purify -> valgrind.
      BUILD/build_mccge.sh:
        Rename purify -> valgrind.
      BUILD/compile-dist:
        Fix that PBXT was missing in source tarball after `BUILD/compile-dist && make dist`
      BUILD/compile-pentium64-max:
        Fix a build problem with BUILD/compile-pentium64-max on CentOS/Fedora Core 10 amd64.
              
        On these systems, there is libz.so but no libz.a. Finding libz.so, ./configure decides
        to use system zlib. But since BUILD/compile-pentium64-max builds a fully static binary
        with -all-static, the link of mysqld fails due to missing libz.a.
              
        Fix by using bundled zlib in the build script.
      BUILD/compile-solaris-sparc-purify:
        Rename purify -> valgrind.
      include/m_string.h:
        Rename purify -> valgrind.
      include/my_global.h:
        Rename purify -> valgrind.
      mysql-test/Makefile.am:
        Fix that PBXT test suite was missing from `make dist` source tarball.
      mysql-test/lib/mtr_unique.pm:
        Better fix to avoid races when chmod'ing the semaphore file.
        (Though using chmod 666 shared files in /tmp/ is still not a very good solution).
      mysql-test/t/pool_of_threads.cnf:
        Fix that test case pool_of_threads fails if run on mysqld with no --with-libevent support.
      mysys/mf_qsort.c:

      Fix Valgrind errors seen in buildbot. · c558b3e0
      unknown authored
      Fix mysql-test-run.pl to not terminate early when warnings in error logs are detected during
      server shutdown. Instead, give a nice summary report at the end of the failures.
      
      Fix code to make 100% sure no failures will go undetected.
      
      Revert earlier wrong change.
      
      Fix race with port allocation semaphore file permissions.
      
      Adjust testsuite to copy with new PBXT engine now in the tree. The PBXT engine causes an
      extra table to appear in the INFORMATION_SCHEMA. This causes different output for a few
      test cases.
      
      dbug/dbug.c:
        If DbugParse() is called multiple times, the stack->keywords for the
        top stack frame could be overwritten without being freed, causing a
        memory leak reported by Valgrind.
      include/my_global.h:
        Add useful macro for different values when Valgrind (HAVE_purify) and not.
      mysql-test/extra/rpl_tests/rpl_auto_increment.test:
        Omit pbxt variables from show variables output.
      mysql-test/include/have_pbxt.inc:
        Add facility to disable test if PBXT engine is not available.
      mysql-test/lib/mtr_report.pm:
        Give a nice summary report at the end of tests of any warnings seen in logs during
        server shutdowns.
      mysql-test/lib/mtr_unique.pm:
        Move chmod 777 to greatly reduce the risk of leaving the port semaphore file unaccessible
        bu other users.
      mysql-test/mysql-test-run.pl:
        Don't abort in case of warnings detected, instead give a nice summary report.
        
        Fix code to make 100% sure no failures will go undetected.
        
        Revert earlier wrong change when master disconnects early.
      mysql-test/r/information_schema.result:
        Omit PBXT INFORMATION_SCHEMA table from output.
        Move part of test to information_schema_all_engines.
      mysql-test/r/information_schema_all_engines.result:
        New file for information_schema tests that depend on which engines are available.
      mysql-test/r/information_schema_db.result:
        Move part of test to information_schema_all_engines.

      mysql-test/t/mysqlshow.test:
        Move part of test to information_schema_all_engines.
      mysql-test/valgrind.supp:
        Add variant suppression (different system library versions).
        Add suppression for problem with inet_ntoa().
      sql/mysqld.cc:
        Fix missing DBUG_RETURN.
        Fix uninitialised thd->connect_utime, likely introduced by pool_of_threads.
      sql/set_var.cc:
        Fix one-byte buffer overflow in several places.
        Fix unsafe use of String::c_ptr() of stack-allocated String buffer.
      sql/sql_select.cc:
        Silence valgrind warning due to GCC bug.
      sql/sql_string.h:
        Document potential problem with String::c_ptr() and String() constructor with caller-supplied buffer.
      storage/archive/azio.c:
        Silence Valgrind false warning for libz.
